Title: Computer-implemented methods and systems for efficient sortation of items based on limited access to item information

Description:
RELATED APPLICATIONS 
     This application is a continuation of U.S. patent application Ser. No. 16/687,756 (now allowed) filed on Nov. 19, 2019, which is hereby incorporated by reference in the present application. 
    
    
     TECHNICAL FIELD 
     The present disclosure generally relates to computerized methods and systems for providing instructions for fast order fulfillment to a user who may be working with a limited scope. In particular, embodiments of the present disclosure relate to inventive and unconventional systems that display a user interface (UI), which expedites order fulfillment by allowing workers to focus on tasks immediately in front of them while the systems optimize the order fulfillment process as a whole and provide only the resources necessary for the workers to complete the tasks. 
     BACKGROUND 
     With proliferation of the Internet, online shopping has become one of the major avenues of commerce. Consumers and businesses are purchasing goods from online vendors more frequently than ever, and the number of transactions and sales revenue are projected to grow year-over-year at a staggering rate. As the scope and volume of e-commerce continue to grow, both a number of different products available online and an average number of purchases made in a given period are growing exponentially. It has thus become very important to optimize processes of fulfilling an order, which starts when a customer places an order and ends when the order is delivered to the customer. 
     Of the different processes that are involved such as retrieving items included in the order, packaging the items, and shipping, various solutions for retrieving the items already exist to make the process more efficient. One common solution is to reorganize items in a group of orders based on their location within a fulfillment center, retrieving the items based on the reorganized groups, and sorting them back to individual orders for packaging. This solution allows efficient retrieval of items from inventory, decreasing distances the workers must travel in order to retrieve the items and making the workers work faster as they gain familiarity with a limited area that they are assigned to. 
     However, this solution introduces new problems when the items must be sorted back to individual orders for packaging. Different items of a single order may have been divided into multiple groups along with items from other orders, where each group may be at different stages of retrieval. Some groups may still be waiting for assignment to a worker for retrieval, some may be in the middle of retrieval, and some may be finished and are ready for sorting. With existing solutions, this mix up is a source of delay, where sorting workers must track where different items of an order are located, prioritize those that are ready for sorting, and the like. Data associated with these information (i.e., status of each item of an order for thousands or millions of orders) may be collected and stored by existing solutions, but the sorting workers often have limited access to such data, and it is impractical to equip every sorting worker with resources to look up necessary information. Even assuming that every sorting worker were provided with the information, it would take too much time for sorting workers to process the enormous amount of data, resulting in decreased productivity. 
     Therefore, there is a need for improved systems and methods for facilitating the sorting process by processing a mountain of data gathered throughout the order fulfillment process and presenting necessary information in a controlled manner, so that workers may be able to focus solely on sorting even with a limited understanding of the overall process. 
     SUMMARY 
     One aspect of the present disclosure is directed to a computer-implemented system for providing instructions to a user. The system may comprise a memory storing operations; and at least one processor configured to execute the operations. The operations may comprise: receiving a first user input of a container identifier, the container identifier corresponding to a physical container comprising one or more items associated with one or more orders; updating, in a networked database, a first container location identifier associated with the container identifier to include a physical location of the computer-implemented system; retrieving, from the networked database, one or more item identifiers associated with the container identifier, the item identifiers corresponding to the items; updating, in the networked database, one or more item location identifiers associated with the item identifiers to include the physical location of the computer-implemented system; receiving a second user input of a first item identifier, the first item identifier corresponding to a first item among the items; based on receiving the second user input, assigning, among one or more locations, a first location to the first item identifier; displaying the instructions to the user for placing the first item at the first location; and updating, in the networked database, a first item location identifier associated with the first item identifier to include the first location. 
     Yet another aspect of the present disclosure is directed to a computer-implemented method for providing instructions to a user. The method may comprise: receiving a first user input of a container identifier, the container identifier corresponding to a physical container comprising one or more items associated with one or more orders; updating, in a networked database, a first container location identifier associated with the container identifier to include a physical location of the computer-implemented system; retrieving, from the networked database, one or more item identifiers associated with the container identifier, the item identifiers corresponding to the items; updating, in the networked database, one or more item location identifiers associated with the item identifiers to include the physical location of the computer-implemented system; receiving a second user input of a first item identifier, the first item identifier corresponding to a first item among the items; based on receiving the second user input, assigning, among one or more locations, a first location to the first item identifier; displaying the instructions to the user for placing the first item at the first location; and updating, in the networked database, a first item location identifier associated with the first item identifier to include the first location. 
     Still further, another aspect of the present disclosure is directed to a computer-implemented system for an efficient sortation of items by a user working under a limited access to information. The system may comprise a memory storing operations; and at least one processor configured to execute the operations. The operations may comprise: receiving a first user input of a container identifier, the container identifier corresponding to a first physical container comprising one or more items associated with one or more orders; updating, in a networked database, a first container location identifier associated with the container identifier to include a physical location of the computer-implemented system; retrieving, from the networked database, one or more item identifiers associated with the container identifier, the item identifiers corresponding to the items; updating, in the networked database, one or more item location identifiers associated with the item identifiers to include the physical location of the computer-implemented system; receiving a second user input of a first item identifier, the first item identifier corresponding to a first item among the items; identifying, among the orders, a first order associated with the first item, wherein the first order comprises a second item associated with a second physical container; based on receiving the second user input, assigning, among one or more locations, a first location to the first item identifier; displaying the instructions to the user for placing the first item at the first location; updating, in the networked database, a first item location identifier associated with the first item identifier to include the first location; receiving, from the networked database, an indication that the second physical container is delayed based on a second container location identifier associated with the second physical container; and displaying the instructions to the user for finalizing the first location without the second item. 
     Other systems, methods, and computer-readable media are also discussed herein.

     DETAILED DESCRIPTION 
     The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar parts. While several illustrative embodiments are described herein, modifications, adaptations and other implementations are possible. For example, substitutions, additions, or modifications may be made to the components and steps illustrated in the drawings, and the illustrative methods described herein may be modified by substituting, reordering, removing, or adding steps to the disclosed methods. Accordingly, the following detailed description is not limited to the disclosed embodiments and examples. Instead, the proper scope of the invention is defined by the appended claims. 
     Embodiments of the present disclosure are directed to a UI that expedites order fulfillment by allowing workers to focus on tasks immediately in front of them while other systems optimize the order fulfillment process as a whole and provide only the resources necessary for the workers to complete the tasks. Specifically, the UI may facilitate a sorting process by processing the mountain of data gathered throughout the order fulfillment process and presenting necessary information in a controlled manner. 
     Referring to  FIG.  1 A , a schematic block diagram  100  illustrating an exemplary embodiment of a system comprising computerized systems for communications enabling shipping, transportation, and logistics operations is shown. As illustrated in  FIG.  1 A , system  100  may include a variety of systems, each of which may be connected to one another via one or more networks. The systems may also be connected to one another via a direct connection, for example, using a cable. The depicted systems include a shipment authority technology (SAT) system  101 , an external front end system  103 , an internal front end system  105 , a transportation system  107 , mobile devices  107 A,  107 B, and  107 C, seller portal  109 , shipment and order tracking (SOT) system  111 , fulfillment optimization (FO) system  113 , fulfillment messaging gateway (FMG)  115 , supply chain management (SCM) system  117 , workforce management system  119 , mobile devices  119 A,  119 B, and  119 C (depicted as being inside of fulfillment center (FC)  200 ), 3 rd  party fulfillment systems  121 A,  121 B, and  121 C, fulfillment center authorization system (FC Auth)  123 , and labor management system (LMS)  125 . 
     SAT system  101 , in some embodiments, may be implemented as a computer system that monitors order status and delivery status. For example, SAT system  101  may determine whether an order is past its Promised Delivery Date (PDD) and may take appropriate action, including initiating a new order, reshipping the items in the non-delivered order, canceling the non-delivered order, initiating contact with the ordering customer, or the like. SAT system  101  may also monitor other data, including output (such as a number of packages shipped during a particular time period) and input (such as the number of empty cardboard boxes received for use in shipping). SAT system  101  may also act as a gateway between different devices in system  100 , enabling communication (e.g., using store-and-forward or other techniques) between devices such as external front end system  103  and FO system  113 . 
     External front end system  103 , in some embodiments, may be implemented as a computer system that enables external users to interact with one or more systems in system  100 . For example, in embodiments where system  100  enables the presentation of systems to enable users to place an order for an item, external front end system  103  may be implemented as a web server that receives search requests, presents item pages, and solicits payment information. For example, external front end system  103  may be implemented as a computer or computers running software such as the Apache HTTP Server, Microsoft Internet Information Services (IIS), NGINX, or the like. In other embodiments, external front end system  103  may run custom web server software designed to receive and process requests from external devices (e.g., mobile device  102 A or computer  102 B), acquire information from databases and other data stores based on those requests, and provide responses to the received requests based on acquired information. 
     In some embodiments, external front end system  103  may include one or more of a web caching system, a database, a search system, or a payment system. In one aspect, external front end system  103  may comprise one or more of these systems, while in another aspect, external front end system  103  may comprise interfaces (e.g., server-to-server, database-to-database, or other network connections) connected to one or more of these systems. 
     An illustrative set of steps, illustrated by  FIGS.  1 B,  1 C,  1 D, and  1 E , will help to describe some operations of external front end system  103 . External front end system  103  may receive information from systems or devices in system  100  for presentation and/or display. For example, external front end system  103  may host or provide one or more web pages, including a Search Result Page (SRP) (e.g.,  FIG.  1 B ), a Single Detail Page (SDP) (e.g.,  FIG.  1 C ), a Cart page (e.g.,  FIG.  1 D ), or an Order page (e.g.,  FIG.  1 E ). A user device (e.g., using mobile device  102 A or computer  102 B) may navigate to external front end system  103  and request a search by entering information into a search box. External front end system  103  may request information from one or more systems in system  100 . For example, external front end system  103  may request information from FO System  113  that satisfies the search request. External front end system  103  may also request and receive (from FO System  113 ) a Promised Delivery Date or “PDD” for each product included in the search results. The PDD, in some embodiments, may represent an estimate of when a package containing the product will arrive at the user&#39;s desired location or a date by which the product is promised to be delivered at the user&#39;s desired location if ordered within a particular period of time, for example, by the end of the day (11:59 PM). (PDD is discussed further below with respect to FO System  113 .) 
     External front end system  103  may prepare an SRP (e.g.,  FIG.  1 B ) based on the information. The SRP may include information that satisfies the search request. For example, this may include pictures of products that satisfy the search request. The SRP may also include respective prices for each product, or information relating to enhanced delivery options for each product, PDD, weight, size, offers, discounts, or the like. External front end system  103  may send the SRP to the requesting user device (e.g., via a network). 
     A user device may then select a product from the SRP, e.g., by clicking or tapping a user interface, or using another input device, to select a product represented on the SRP. The user device may formulate a request for information on the selected product and send it to external front end system  103 . In response, external front end system  103  may request information related to the selected product. For example, the information may include additional information beyond that presented for a product on the respective SRP. This could include, for example, shelf life, country of origin, weight, size, number of items in package, handling instructions, or other information about the product. The information could also include recommendations for similar products (based on, for example, big data and/or machine learning analysis of customers who bought this product and at least one other product), answers to frequently asked questions, reviews from customers, manufacturer information, pictures, or the like. 
     External front end system  103  may prepare an SDP (Single Detail Page) (e.g.,  FIG.  1 C ) based on the received product information. The SDP may also include other interactive elements such as a “Buy Now” button, a “Add to Cart” button, a quantity field, a picture of the item, or the like. The SDP may further include a list of sellers that offer the product. The list may be ordered based on the price each seller offers such that the seller that offers to sell the product at the lowest price may be listed at the top. The list may also be ordered based on the seller ranking such that the highest ranked seller may be listed at the top. The seller ranking may be formulated based on multiple factors, including, for example, the seller&#39;s past track record of meeting a promised PDD. External front end system  103  may deliver the SDP to the requesting user device (e.g., via a network). 
     The requesting user device may receive the SDP which lists the product information. Upon receiving the SDP, the user device may then interact with the SDP. For example, a user of the requesting user device may click or otherwise interact with a “Place in Cart” button on the SDP. This adds the product to a shopping cart associated with the user. The user device may transmit this request to add the product to the shopping cart to external front end system  103 . 
     External front end system  103  may generate a Cart page (e.g.,  FIG.  1 D ). The Cart page, in some embodiments, lists the products that the user has added to a virtual “shopping cart.” A user device may request the Cart page by clicking on or otherwise interacting with an icon on the SRP, SDP, or other pages. The Cart page may, in some embodiments, list all products that the user has added to the shopping cart, as well as information about the products in the cart such as a quantity of each product, a price for each product per item, a price for each product based on an associated quantity, information regarding PDD, a delivery method, a shipping cost, user interface elements for modifying the products in the shopping cart (e.g., deletion or modification of a quantity), options for ordering other product or setting up periodic delivery of products, options for setting up interest payments, user interface elements for proceeding to purchase, or the like. A user at a user device may click on or otherwise interact with a user interface element (e.g., a button that reads “Buy Now”) to initiate the purchase of the product in the shopping cart. Upon doing so, the user device may transmit this request to initiate the purchase to external front end system  103 . 
     External front end system  103  may generate an Order page (e.g.,  FIG.  1 E ) in response to receiving the request to initiate a purchase. The Order page, in some embodiments, re-lists the items from the shopping cart and requests input of payment and shipping information. For example, the Order page may include a section requesting information about the purchaser of the items in the shopping cart (e.g., name, address, e-mail address, phone number), information about the recipient (e.g., name, address, phone number, delivery information), shipping information (e.g., speed/method of delivery and/or pickup), payment information (e.g., credit card, bank transfer, check, stored credit), user interface elements to request a cash receipt (e.g., for tax purposes), or the like. External front end system  103  may send the Order page to the user device. 
     The user device may enter information on the Order page and click or otherwise interact with a user interface element that sends the information to external front end system  103 . From there, external front end system  103  may send the information to different systems in system  100  to enable the creation and processing of a new order with the products in the shopping cart. 
     In some embodiments, external front end system  103  may be further configured to enable sellers to transmit and receive information relating to orders. 
     Internal front-end system  105 , in some embodiments, may be implemented as a computer system that enables internal users (e.g., employees of an organization that owns, operates, or leases system  100 ) to interact with one or more systems in system  100 . For example, in embodiments where network  101  enables the presentation of systems to enable users to place an order for an item, internal front end system  105  may be implemented as a web server that enables internal users to view diagnostic and statistical information about orders, modify item information, or review statistics relating to orders. For example, internal front-end system  105  may be implemented as a computer or computers running software such as the Apache HTTP Server, Microsoft Internet Information Services (IIS), NGINX, or the like. In other embodiments, internal front end system  105  may run custom web server software designed to receive and process requests from systems or devices depicted in system  100  (as well as other devices not depicted), acquire information from databases and other data stores based on those requests, and provide responses to the received requests based on acquired information. 
     In some embodiments, internal front-end system  105  may include one or more of a web caching system, a database, a search system, a payment system, an analytics system, an order monitoring system, or the like. In one aspect, internal front end system  105  may comprise one or more of these systems, while in another aspect, internal front end system  105  may comprise interfaces (e.g., server-to-server, database-to-database, or other network connections) connected to one or more of these systems. 
     Transportation system  107 , in some embodiments, may be implemented as a computer system that enables communication between systems or devices in system  100  and mobile devices  107 A- 107 C. Transportation system  107 , in some embodiments, may receive information from one or more mobile devices  107 A- 107 C (e.g., mobile phones, smart phones, PDAs, or the like). For example, in some embodiments, mobile devices  107 A- 107 C may comprise devices operated by delivery workers. The delivery workers, who may be permanent, temporary, or shift employees, may utilize mobile devices  107 A- 107 C to effect delivery of packages containing the products ordered by users. For example, to deliver a package, the delivery worker may receive a notification on a mobile device indicating which package to deliver and where to deliver it. Upon arriving at the delivery location, the delivery worker may locate the package (e.g., in the back of a truck or in a crate of packages), scan or otherwise capture data associated with an identifier on the package (e.g., a barcode, an image, a text string, an RFID tag, or the like) using the mobile device, and deliver the package (e.g., by leaving it at a front door, leaving it with a security guard, handing it to the recipient, or the like). In some embodiments, the delivery worker may capture photo(s) of the package and/or may obtain a signature using the mobile device. The mobile device may send information to transportation system  107  including information about the delivery, including, for example, time, date, GPS location, photo(s), an identifier associated with the delivery worker, an identifier associated with the mobile device, or the like. Transportation system  107  may store this information in a database (not pictured) for access by other systems in system  100 . Transportation system  107  may, in some embodiments, use this information to prepare and send tracking data to other systems indicating the location of a particular package. 
     In some embodiments, certain users may use one kind of mobile device (e.g., permanent workers may use a specialized PDA with custom hardware such as a barcode scanner, stylus, and other devices) while other users may use other kinds of mobile devices (e.g., temporary or shift workers may utilize off-the-shelf mobile phones and/or smartphones). 
     In some embodiments, transportation system  107  may associate a user with each device. For example, transportation system  107  may store an association between a user (represented by, e.g., a user identifier, an employee identifier, or a phone number) and a mobile device (represented by, e.g., an International Mobile Equipment Identity (IMEI), an International Mobile Subscription Identifier (IMSI), a phone number, a Universal Unique Identifier (UUID), or a Globally Unique Identifier (GUID)). Transportation system  107  may use this association in conjunction with data received on deliveries to analyze data stored in the database in order to determine, among other things, a location of the worker, an efficiency of the worker, or a speed of the worker. 
     Seller portal  109 , in some embodiments, may be implemented as a computer system that enables sellers or other external entities to electronically communicate with one or more systems in system  100 . For example, a seller may utilize a computer system (not pictured) to upload or provide product information, order information, contact information, or the like, for products that the seller wishes to sell through system  100  using seller portal  109 . 
     Shipment and order tracking system  111 , in some embodiments, may be implemented as a computer system that receives, stores, and forwards information regarding the location of packages containing products ordered by customers (e.g., by a user using devices  102 A- 102 B). In some embodiments, shipment and order tracking system  111  may request or store information from web servers (not pictured) operated by shipping companies that deliver packages containing products ordered by customers. 
     In some embodiments, shipment and order tracking system  111  may request and store information from systems depicted in system  100 . For example, shipment and order tracking system  111  may request information from transportation system  107 . As discussed above, transportation system  107  may receive information from one or more mobile devices  107 A- 107 C (e.g., mobile phones, smart phones, PDAs, or the like) that are associated with one or more of a user (e.g., a delivery worker) or a vehicle (e.g., a delivery truck). In some embodiments, shipment and order tracking system  111  may also request information from workforce management system (WMS)  119  to determine the location of individual products inside of a fulfillment center (e.g., fulfillment center  200 ). Shipment and order tracking system  111  may request data from one or more of transportation system  107  or WMS  119 , process it, and present it to a device (e.g., user devices  102 A and  102 B) upon request. 
     Fulfillment optimization (FO) system  113 , in some embodiments, may be implemented as a computer system that stores information for customer orders from other systems (e.g., external front end system  103  and/or shipment and order tracking system  111 ). FO system  113  may also store information describing where particular items are held or stored. For example, certain items may be stored only in one fulfillment center, while certain other items may be stored in multiple fulfillment centers. In still other embodiments, certain fulfilment centers may be designed to store only a particular set of items (e.g., fresh produce or frozen products). FO system  113  stores this information as well as associated information (e.g., quantity, size, date of receipt, expiration date, etc.). 
     FO system  113  may also calculate a corresponding PDD (promised delivery date) for each product. The PDD, in some embodiments, may be based on one or more factors. For example, FO system  113  may calculate a PDD for a product based on a past demand for a product (e.g., how many times that product was ordered during a period of time), an expected demand for a product (e.g., how many customers are forecast to order the product during an upcoming period of time), a network-wide past demand indicating how many products were ordered during a period of time, a network-wide expected demand indicating how many products are expected to be ordered during an upcoming period of time, one or more counts of the product stored in each fulfillment center  200 , which fulfillment center stores each product, expected or current orders for that product, or the like. 
     In some embodiments, FO system  113  may determine a PDD for each product on a periodic basis (e.g., hourly) and store it in a database for retrieval or sending to other systems (e.g., external front end system  103 , SAT system  101 , shipment and order tracking system  111 ). In other embodiments, FO system  113  may receive electronic requests from one or more systems (e.g., external front end system  103 , SAT system  101 , shipment and order tracking system  111 ) and calculate the PDD on demand. 
     Fulfilment messaging gateway (FMG)  115 , in some embodiments, may be implemented as a computer system that receives a request or response in one format or protocol from one or more systems in system  100 , such as FO system  113 , converts it to another format or protocol, and forward it in the converted format or protocol to other systems, such as WMS  119  or 3 rd  party fulfillment systems  121 A,  121 B, or  121 C, and vice versa. 
     Supply chain management (SCM) system  117 , in some embodiments, may be implemented as a computer system that performs forecasting functions. For example, SCM system  117  may forecast a level of demand for a particular product based on, for example, based on a past demand for products, an expected demand for a product, a network-wide past demand, a network-wide expected demand, a count products stored in each fulfillment center  200 , expected or current orders for each product, or the like. In response to this forecasted level and the amount of each product across all fulfillment centers, SCM system  117  may generate one or more purchase orders to purchase and stock a sufficient quantity to satisfy the forecasted demand for a particular product. 
     Workforce management system (WMS)  119 , in some embodiments, may be implemented as a computer system that monitors workflow. For example, WMS  119  may receive event data from individual devices (e.g., devices  107 A- 107 C or  119 A- 119 C) indicating discrete events. For example, WMS  119  may receive event data indicating the use of one of these devices to scan a package. As discussed below with respect to fulfillment center  200  and  FIG.  2   , during the fulfillment process, a package identifier (e.g., a barcode or RFID tag data) may be scanned or read by machines at particular stages (e.g., automated or handheld barcode scanners, RFID readers, high-speed cameras, devices such as tablet  119 A, mobile device/PDA  1198 , computer  119 C, or the like). WMS  119  may store each event indicating a scan or a read of a package identifier in a corresponding database (not pictured) along with the package identifier, a time, date, location, user identifier, or other information, and may provide this information to other systems (e.g., shipment and order tracking system  111 ). 
     WMS  119 , in some embodiments, may store information associating one or more devices (e.g., devices  107 A- 107 C or  119 A- 119 C) with one or more users associated with system  100 . For example, in some situations, a user (such as a part- or full-time employee) may be associated with a mobile device in that the user owns the mobile device (e.g., the mobile device is a smartphone). In other situations, a user may be associated with a mobile device in that the user is temporarily in custody of the mobile device (e.g., the user checked the mobile device out at the start of the day, will use it during the day, and will return it at the end of the day). 
     WMS  119 , in some embodiments, may maintain a work log for each user associated with system  100 . For example, WMS  119  may store information associated with each employee, including any assigned processes (e.g., unloading trucks, picking items from a pick zone, rebin wall work, packing items), a user identifier, a location (e.g., a floor or zone in a fulfillment center  200 ), a number of units moved through the system by the employee (e.g., number of items picked, number of items packed), an identifier associated with a device (e.g., devices  119 A- 119 C), or the like. In some embodiments, WMS  119  may receive check-in and check-out information from a timekeeping system, such as a timekeeping system operated on a device  119 A- 119 C. 
     3 rd  party fulfillment (3PL) systems  121 A- 121 C, in some embodiments, represent computer systems associated with third-party providers of logistics and products. For example, while some products are stored in fulfillment center  200  (as discussed below with respect to  FIG.  2   ), other products may be stored off-site, may be produced on demand, or may be otherwise unavailable for storage in fulfillment center  200 . 3PL systems  121 A- 121 C may be configured to receive orders from FO system  113  (e.g., through FMG  115 ) and may provide products and/or services (e.g., delivery or installation) to customers directly. In some embodiments, one or more of 3PL systems  121 A- 121 C may be part of system  100 , while in other embodiments, one or more of 3PL systems  121 A- 121 C may be outside of system  100  (e.g., owned or operated by a third-party provider). 
     Fulfillment Center Auth system (FC Auth)  123 , in some embodiments, may be implemented as a computer system with a variety of functions. For example, in some embodiments, FC Auth  123  may act as a single sign on (SSO) service for one or more other systems in system  100 . For example, FC Auth  123  may enable a user to log in via internal front end system  105 , determine that the user has similar privileges to access resources at shipment and order tracking system  111 , and enable the user to access those privileges without requiring a second log in process. FC Auth  123 , in other embodiments, may enable users (e.g., employees) to associate themselves with a particular task. For example, some employees may not have an electronic device (such as devices  119 A- 119 C) and may instead move from task to task, and zone to zone, within a fulfillment center  200 , during the course of a day. FC Auth  123  may be configured to enable those employees to indicate what task they are performing and what zone they are in at different times of day. 
     Labor management system (LMS)  125 , in some embodiments, may be implemented as a computer system that stores attendance and overtime information for employees (including full-time and part-time employees). For example, LMS  125  may receive information from FC Auth  123 , WMA  119 , devices  119 A- 119 C, transportation system  107 , and/or devices  107 A- 107 C. 
     The particular configuration depicted in  FIG.  1 A  is an example only. For example, while  FIG.  1 A  depicts FC Auth system  123  connected to FO system  113 , not all embodiments require this particular configuration. Indeed, in some embodiments, the systems in system  100  may be connected to one another through one or more public or private networks, including the Internet, an Intranet, a WAN (Wide-Area Network), a MAN (Metropolitan-Area Network), a wireless network compliant with the IEEE 802.11a/b/g/n Standards, a leased line, or the like. In some embodiments, one or more of the systems in system  100  may be implemented as one or more virtual servers implemented at a data center, server farm, or the like. 
       FIG.  2    depicts a fulfillment center  200 . Fulfillment center  200  is an example of a physical location that stores items for shipping to customers when ordered. Fulfillment center (FC)  200  may be divided into multiple zones, each of which are depicted in  FIG.  2   . These “zones,” in some embodiments, may be thought of as virtual divisions between different stages of a process of receiving items, storing the items, retrieving the items, and shipping the items. So while the “zones” are depicted in  FIG.  2   , other divisions of zones are possible, and the zones in  FIG.  2    may be omitted, duplicated, or modified in some embodiments. 
     Inbound zone  203  represents an area of FC  200  where items are received from sellers who wish to sell products using system  100  from  FIG.  1 A . For example, a seller may deliver items  202 A and  202 B using truck  201 . Item  202 A may represent a single item large enough to occupy its own shipping pallet, while item  202 B may represent a set of items that are stacked together on the same pallet to save space. 
     A worker will receive the items in inbound zone  203  and may optionally check the items for damage and correctness using a computer system (not pictured). For example, the worker may use a computer system to compare the quantity of items  202 A and  202 B to an ordered quantity of items. If the quantity does not match, that worker may refuse one or more of items  202 A or  202 B. If the quantity does match, the worker may move those items (using, e.g., a dolly, a handtruck, a forklift, or manually) to buffer zone  205 . Buffer zone  205  may be a temporary storage area for items that are not currently needed in the picking zone, for example, because there is a high enough quantity of that item in the picking zone to satisfy forecasted demand. In some embodiments, forklifts  206  operate to move items around buffer zone  205  and between inbound zone  203  and drop zone  207 . If there is a need for items  202 A or  202 B in the picking zone (e.g., because of forecasted demand), a forklift may move items  202 A or  202 B to drop zone  207 . 
     Drop zone  207  may be an area of FC  200  that stores items before they are moved to picking zone  209 . A worker assigned to the picking task (a “picker”) may approach items  202 A and  202 B in the picking zone, scan a barcode for the picking zone, and scan barcodes associated with items  202 A and  202 B using a mobile device (e.g., device  119 B). The picker may then take the item to picking zone  209  (e.g., by placing it on a cart or carrying it). 
     Picking zone  209  may be an area of FC  200  where items  208  are stored on storage units  210 . In some embodiments, storage units  210  may comprise one or more of physical shelving, bookshelves, boxes, totes, refrigerators, freezers, cold stores, or the like. In some embodiments, picking zone  209  may be organized into multiple floors. In some embodiments, workers or machines may move items into picking zone  209  in multiple ways, including, for example, a forklift, an elevator, a conveyor belt, a cart, a handtruck, a dolly, an automated robot or device, or manually. For example, a picker may place items  202 A and  202 B on a handtruck or cart in drop zone  207  and walk items  202 A and  202 B to picking zone  209 . 
     A picker may receive an instruction to place (or “stow”) the items in particular spots in picking zone  209 , such as a particular space on a storage unit  210 . For example, a picker may scan item  202 A using a mobile device (e.g., device  119 B). The device may indicate where the picker should stow item  202 A, for example, using a system that indicate an aisle, shelf, and location. The device may then prompt the picker to scan a barcode at that location before stowing item  202 A in that location. The device may send (e.g., via a wireless network) data to a computer system such as WMS  119  in  FIG.  1 A  indicating that item  202 A has been stowed at the location by the user using device  1198 . 
     Once a user places an order, a picker may receive an instruction on device  1198  to retrieve one or more items  208  from storage unit  210 . The picker may retrieve item  208 , scan a barcode on item  208 , and place it on transport mechanism  214 . While transport mechanism  214  is represented as a slide, in some embodiments, transport mechanism may be implemented as one or more of a conveyor belt, an elevator, a cart, a forklift, a handtruck, a dolly, a cart, or the like. Item  208  may then arrive at packing zone  211 . 
     Packing zone  211  may be an area of FC  200  where items are received from picking zone  209  and packed into boxes or bags for eventual shipping to customers. In packing zone  211 , a worker assigned to receiving items (a “rebin worker”) will receive item  208  from picking zone  209  and determine what order it corresponds to. For example, the rebin worker may use a device, such as computer  119 C, to scan a barcode on item  208 . Computer  119 C may indicate visually which order item  208  is associated with. This may include, for example, a space or “cell” on a wall  216  that corresponds to an order. Once the order is complete (e.g., because the cell contains all items for the order), the rebin worker may indicate to a packing worker (or “packer”) that the order is complete. The packer may retrieve the items from the cell and place them in a box or bag for shipping. The packer may then send the box or bag to a hub zone  213 , e.g., via forklift, cart, dolly, handtruck, conveyor belt, manually, or otherwise. 
     Hub zone  213  may be an area of FC  200  that receives all boxes or bags (“packages”) from packing zone  211 . Workers and/or machines in hub zone  213  may retrieve package  218  and determine which portion of a delivery area each package is intended to go to, and route the package to an appropriate camp zone  215 . For example, if the delivery area has two smaller sub-areas, packages will go to one of two camp zones  215 . In some embodiments, a worker or machine may scan a package (e.g., using one of devices  119 A- 119 C) to determine its eventual destination. Routing the package to camp zone  215  may comprise, for example, determining a portion of a geographical area that the package is destined for (e.g., based on a postal code) and determining a camp zone  215  associated with the portion of the geographical area. 
     Camp zone  215 , in some embodiments, may comprise one or more buildings, one or more physical spaces, or one or more areas, where packages are received from hub zone  213  for sorting into routes and/or sub-routes. In some embodiments, camp zone  215  is physically separate from FC  200  while in other embodiments camp zone  215  may form a part of FC  200 . 
     Workers and/or machines in camp zone  215  may determine which route and/or sub-route a package  220  should be associated with, for example, based on a comparison of the destination to an existing route and/or sub-route, a calculation of workload for each route and/or sub-route, the time of day, a shipping method, the cost to ship the package  220 , a PDD associated with the items in package  220 , or the like. In some embodiments, a worker or machine may scan a package (e.g., using one of devices  119 A- 119 C) to determine its eventual destination. Once package  220  is assigned to a particular route and/or sub-route, a worker and/or machine may move package  220  to be shipped. In exemplary  FIG.  2   , camp zone  215  includes a truck  222 , a car  226 , and delivery workers  224 A and  224 B. In some embodiments, truck  222  may be driven by delivery worker  224 A, where delivery worker  224 A is a full-time employee that delivers packages for FC  200  and truck  222  is owned, leased, or operated by the same company that owns, leases, or operates FC  200 . In some embodiments, car  226  may be driven by delivery worker  224 B, where delivery worker  224 B is a “flex” or occasional worker that is delivering on an as-needed basis (e.g., seasonally). Car  226  may be owned, leased, or operated by delivery worker  224 B. 
       FIG.  3    is a diagrammatic illustration of an exemplary order fulfillment process  300 . Order fulfillment process  300  may begin when customers places orders via external front-end system  103 . In some embodiments, FO system  113  may aggregate the orders for a predetermined period of time until an order set  310  is created, comprising of orders  311 - 316 . Each of the orders  311 - 316  may include any combination of items (e.g., items a-k). For example in  FIG.  3   , order  311  includes items a, b, and c; order  312  includes items a, h, and i; order  313  includes items a, d, g, and k; order  314  includes items e and f; order  315  includes items a, a, b, and j (i.e., two of item a and one each of items b and j); and order  316  includes two of item e. 
     In order to expedite the picking process described above, FO system  113 , in some embodiments, may reorganize the purchased items in orders  311 - 316  into one or more batches  321 - 323  based on, for example, each item&#39;s location within FC  200 . For example in  FIG.  3   , batch  321  includes five of item a, two of item b, and one each of items c and d; batch  322  includes three of item  3  and one each of items f and g; and batch  323  includes one each of items h, i, j, and k. In some embodiments, FO system  113  may assign each batch to different workers (e.g., pickers), who may then pick each item in their respective batch from picking zone  209 . Although pickers are described as human, it should be noted that pickers may be implemented as automated machines and not limited to the examples described herein. For ease of explanation without causing ambiguity, pickers are described as individuals hereinafter unless specifically stated otherwise. 
     In further embodiments, items in each batch may be divided into one or more subgroups based on a capacity of containers  321 A,  321 B,  322 A,  323 A, and  323 B. For example in  FIG.  3   , items assigned to batch  321  are split between containers  321 A and  321 B, which contain five of item a; and two of item b and one each of items c and d, respectively. Similarly, items assigned to batch  323  are split between containers  323 A and  323 B, which contain each of items h, i, and j; and one of item k, respectively. On the other hand, all of the items assigned to batch  322  are contained in container  322 A, which indicates that combined weight and volume of the items are within a weight capacity and a volume capacity of container  322 A. Although items in each batch are divided into one or two containers, the number is only exemplary and a batch may contain more than two containers. 
     Once all of the items in a container are picked, the picker may transfer the container to packing zone  211  via transport mechanism  214  as described above with respect to  FIG.  2   . It should be noted, however, that because items in each container may be picked by different pickers, each container may arrive packing zone  211  at different times. 
     In packing zone  211 , rebin workers will receive the containers and sort the items therein onto one or more sorting apparatuses  330 A-C. Although rebin workers are described as human, it should be noted that rebin workers may be implemented as automated machines and not limited to the examples described herein. For example, rebin workers may be implemented as a complex network of conveyor belts or robots configured to sort individual items. For ease of explanation without causing ambiguity, rebin workers are described as individuals hereinafter unless specifically stated otherwise. 
     In some embodiments, sorting apparatuses  330 A-C may comprise one or more of a physical shelving, bookshelves, or an area, where multiple spaces or “cells” are arranged. For example in  FIG.  3   , sorting apparatuses  330 A-C may comprise multiple cells in a grid marked by rows A, B, and C and columns  01 ,  02 , and  03 . Other arrangements of spaces and means of identification are also within the scope of the current disclosure. In some embodiments, each space or cell in sorting apparatus  330  may correspond to a particular order. Once rebin workers sort all purchased items for a particular order into a cell, the rebin worker may finalize the cell, which signals a packer to package the items in the cell into a box and send it out for delivery. 
     Sorting apparatuses  330 A-C depict different states of a same sorting apparatus as rebin workers sort items in containers  321 B,  323 A, and  321 A onto the sorting apparatus. For example, at the first stage, sorting apparatus  330 A may contain items p and s in cell A 02  and item q in cell C 01 . Items p, s, and q may be portions of other orders that were sorted onto sorting apparatus  330 A from other containers. The other cells in sorting apparatus  330 A: cells A 01 , A 03 , B 01 , B 02 , B 03 , C 02 , and C 03  may be empty and not associated with any order. 
     As rebin workers receive container  321 B and  323 A and begin sorting them into sorting apparatus  330 A, FO system  113  may assign associated orders to different cells. For example, FO system  113  may assign: order  312 , which correspond to items h and i of container  323 A, to cell A 03 ; order  311 , which correspond to items b and c of container  321 B, to cell B 01 ; order  315 , which correspond to items b and j of containers  321 B and  323 A, to cell B 03 ; and order  313 , which correspond to item d of container  321 B, to cell C 03 . Sorting apparatus  330 B depicts a state of sorting apparatus  330 A after the rebin workers have finished sorting all items from containers  321 B and  323 A. 
     As rebin workers receive container  321 A and begin sorting again, FO system  113  may assign each item a from container  321 A to different orders already on sorting apparatus  330 B. And as depicted in sorting apparatus  330 C once the sorting is complete, cells A 03 , B 01 , and B 03  may contain all items associated with the corresponding orders  312 ,  311 , and  315 , respectively, while cell C 03  is still missing items g and k. Containers  322 A and  323 B will need to arrive at packing zone  211  in order for rebin workers to finish sorting all items of order  313  and order  313  is ready for packaging. In some embodiments, rebin workers may not know where other containers are, whether cells A 03 , B 01 , or B 03  are complete, when cells A 02 , C 01 , and C 03  may be complete, how many items need to be sorted into any of the cells, or the like. 
     As described above, however, currently disclosed embodiments allow rebin workers to focus solely on sorting items from one container to a cell designated by FO system  113 , while FO system  113  gathers data associated with each item, order, batch, and container generated throughout order fulfillment process  300  and within FC  200 , make necessary determinations to facilitate fulfillment of each order, and present appropriate instructions to rebin workers. 
     In some embodiments, various systems and UI described herein may be configured to receive user inputs of different identifiers such as an order identifier, item identifier, container identifier, and the like. When a user input of a particular identifier is received, however, the systems and UI must be able to parse the identifier, recognize which type of identifier it is, and take appropriate actions.  FIG.  4    is a flowchart of an exemplary computerized process  400  for recognizing the type of an identifier received through a user input. Process  400  may be performed by any of processors associated with any systems described above in  FIG.  1 A . 
     In some embodiments, step  401  of process  400  may comprise receiving a user input, via an input device (e.g., a camera, a scanner, or a keyboard) configured to read or capture a physical identifier (e.g., a barcode, a Quick Response (QR) code, or an image) of an unknown identifier. In some embodiments, the user input may be an optical reading of a barcode, an image of a QR code, a text input of a series of characters, or an image of a series of characters. 
     At step  402 , process  400  may comprise parsing the unknown identifier to extract a series of characters such as a universal product code (UPC), a stock keeping unit (SKU), or a series of characters formatted in a predetermined pattern. The characters may include alphanumeric characters, special characters, or foreign-language characters. Such parsing may involve decoding a barcode, decoding a QR code, performing an optical character recognition (OCR) or the like. 
     Process  400  may further comprise, at step  403  recognizing a pattern in the extracted series of characters, where each pattern is predefined to indicate the type of identifier. Recognizing the pattern, at step  403 , allows process  400  to identify a type for the unknown identifier, at step  404 . For example, the pattern may comprise first three characters of the extracted series of characters, where “WKS” indicates that the unknown identifier is a workstation identifier while “STA” indicates that the unknown identifier is a sorting apparatus identifier. 
     Once the identifier&#39;s type is recognized, the processor, at step  405 , may query any of the networked systems such as WMS  119 , LMS  125 , a database of orders within FO system  113 , and a database of items within FO system  113  as appropriate to obtain corresponding information. 
     At step  406 , the queried system or the processor may identify a matching identifier from its records based on a search function or an index. 
     At step  407 , the processor may retrieve an information corresponding to the matching identifier. 
       FIG.  5    is a flowchart of an exemplary computerized process  500  for providing instructions for sorting items. In one aspect, process  500  may be performed by FO system  113  and communicated to a rebin worker via computer  119 C. In another aspect, process  500  may be performed by computer  119 C based on data from FO system  113  and communicated to a rebin worker. Furthermore, in some embodiments, process  500  may be repeated multiple times as a rebin worker sorts each container, wherein steps  503 - 506  may be repeated multiple time for each container as the rebin worker scans each item in the container. It should be noted that any step in process  500  that involves receiving any type of identifier (e.g., step  501 ) may involve recognizing the type of the received identifier described above with respect to  FIG.  4   . 
     At step  501 , computer  119 C may receive a user input of a container identifier. In response, at step  502 , computer  119 C may retrieve, from FO system  113 , one or more item identifiers associated with the container identifier, wherein each of the item identifiers are also associated with an order. In some embodiments, the container identifier may correspond to a container (e.g., container  321 B of  FIG.  3   ) that arrived at packing zone  211  with one or more items contained therein. As described above, the user (e.g., a rebin worker) is then instructed to scan each item in the container and place the item at a particular location on a sorting apparatus as assigned by computer  119 C. In some embodiments, the sequence in which the user scans the items may not affect process  500 . 
     At step  503 , computer  119 C may receive another user input of an item identifier corresponding to an item in the container that the rebin worker currently scanned. In response, computer  119 C may identify, at step  504 , an order associated with the current item so that computer  119 C may assign, at step  505 , a location on the sorting apparatus to the item identifier of the current item. In some embodiments, computer  119 C may also transmit a signal to FO system  113 , which updates an order information associated with the identified order to reflect that the item is being sorted at packing zone  211 . 
     Assigning a location at step  505 , in some embodiments, may involve a consideration of a number of factors. In one aspect, computer  119 C may determine whether the identified order matches any of the orders already assigned to a location on the sorting apparatus. Computer  119 C may use an order identifier corresponding to the identified order as a key to search through a database in FO system  113  or a database in computer  119 C that stores association data between order identifiers and locations on the sorting apparatus. 
     When a match is found, computer  119 C may assign the same location to the item identifier of the current item. When no match is found, however, indicating that the current item is the first item of the identified order to be sorted, computer  119 C may assign a new location among any location on the sorting apparatus that is not currently assigned to an order (i.e., the location is empty) by adding a database entry to the database in FO system  113  or the database in computer  119 C, associating the new location with the identified order identifier. 
     In some embodiments when more than one locations are empty, computer  119 C may assign the new location based on at least one of a total weight of the items associated with the identified order, total weights of items associated with orders assigned to other locations on the sorting apparatus, or total weight of items associated with orders to be assigned to the sorting apparatus as determined by the items held in the currently scanned container. In some embodiments, computer  119 C may rank the total weights of the orders already assigned or will be assigned to the sorting apparatus, including the total weight of the identified order, and assign a location to the identified order so that the heavier orders are assigned to lower rows of the sorting apparatus while lighter orders are assigned to the upper rows. Other processes of assigning new locations are also described in U.S. patent application Ser. No. 16/276,722, entitled “System and Method of Sorting Apparatus Cell Allocation for Fast E-Commerce Order Fulfillment,” which is incorporated herein by reference in its entirety. 
     At step  506 , computer  119 C may display instructions for the rebin worker to place the current item at the assigned location by generating an indicator for presentation to the rebin worker for placing the current item at the assigned location. The indicator may be any combination of any number of a visual indicator (e.g., an icon, a text, or a blinking screen), an acoustic indicator (e.g., a beep, a voice, or a ring), or a tactile indicator (e.g., a vibration). In some embodiments, as an indicator, computer  119 C may display a location identifier (e.g., text “B 02 ” which corresponds to cell B 02  on sorting apparatuses  330 A-C) on its screen to indicate that the current item a should be placed at the location associated with the location identifier (i.e., cell B 02 ). 
       FIGS.  6 A-C ,  7 A-H, and  8 A-B are exemplary embodiments of UI consistent with performing any of the disclosed processes. It should be noted that any function described with respect to  FIGS.  6 A-C ,  7 A-H, and  8 A-B that involves receiving any type of identifier (e.g., for workstation ID textbox  605 ) may involve recognizing the type of the received identifier described above with respect to  FIG.  4   . In some embodiments, the UI elements described herein may be displayed, for example, on a display device connected to computer  119 C. 
       FIG.  6 A  is an exemplary embodiment of an initialization UI  600 A from which a user (e.g., a rebin worker) may setup his or her work environment (i.e., where the user will work for a given period of time). In some embodiments, initialization UI  600 A may comprise GUI elements such as buttons, textboxes, or images configured to receive user input or display information. In particular, initialization UI  600 A includes a location ID textbox  601  that indicates the location of computer  119 C (e.g., a name of FC  200 , a floor or a zone within FC  200 ); a user ID textbox  602  that indicates an identity of the user; and a log out button  603  that allows the user to log out of computer  119 C. In some embodiments, the textboxes may be configured to serve also as a button that can perform certain actions in response to a user input. 
     In some embodiments, initialization UI  600 A further comprises a workstation ID input box  605  configured to receive a user input of a workstation identifier (ID) of a particular workstation (e.g., computer  119 C) for his or her use. The user may input the workstation ID by scanning an identifier (e.g., a barcode, an image, a Quick Response (QR) code, a text string, an RFID tag) on computer  119 C using an input device (e.g., RFID reader, camera, or scanner) or entering the same using a manual input device (e.g., keyboard, mouse, virtual keyboard on a touchscreen). Having the user scan or enter a workstation ID of computer  119 C at the beginning of each work session as disclosed may allow a greater flexibility in assigning different workers to different locations or tasks based on need. For example, a worker may be initially assigned to work at computer  119 C in packing zone  211  but get transferred to picking zone  209  at a later time due to a shifting demand. 
     In some embodiments, initialization UI  600 A may also comprise a message box  604  configured to display a message to the user from time to time; a task list button  607  configured to display a consolidated task list for the user; a finalized cell status button  608  configured to display a summary screen of finalized cells; an auto assign text box  609  and an auto assign toggle button  610  configured to select and indicate whether computer  119 C may assign a new container to the user. Each of these UI elements of initialization UI  600 A and their associated functions are described below in more detail with respect to  FIGS.  6 B,  7 A,  8 A, and  8 B . 
     In some embodiments, initialization UI  600 A may also comprise a container pane  620  configured to display at least one of information on a currently scanned container or an item therein, or an instruction for the user. In the embodiment shown in  FIG.  6 A , for example, container pane  620  is configured to display an instruction for the user to scan a workstation ID. Alternatively or additionally, initialization UI  600 A may comprise an item pane  630  configured to display information on at least one of a currently scanned item, a location assigned to the item, other items associated with the same order as the currently scanned item, or the like. Container pane  620  and item pane  630  are described below in more detail with respect to  FIGS.  7 A- 7 H . 
     Upon a successful identification of a workstation ID based on a user input received in response to the instruction displayed in container pane  620  of  FIG.  6 A , computer  119 C may display initialization UI  600 B of  FIG.  6 B , a version of initialization UI  600 A with a workstation ID displayed in workstation ID input box  605 . In some embodiments, container pane  620  may now display an instruction to scan a sorting apparatus ID. 
     In some embodiments, initialization UI  600 B may comprise a sorting apparatus ID input box  606  configured to receive a user input of a sorting apparatus ID of a particular sorting apparatus. The user may input the sorting apparatus ID by scanning an identifier (e.g., a barcode, an image, a Quick Response (QR) code, a text string, an RFID tag) on a sorting apparatus using an input device (e.g., RFID reader, camera, or scanner) or entering the same using a manual input device (e.g., keyboard, mouse, virtual keyboard on a touchscreen). In some embodiments, FO system  113  may store location information of one or more sorting apparatuses and available computers, and automatically assign a sorting apparatus to located nearest to computer  119 C. In this case, FO system  113  may transmit a signal to computer  119 C configured to input the sorting apparatus ID of the automatically assigned sorting apparatus. to sorting apparatus ID input box  606 . 
     In some embodiments, FO system  113  may associate the locations of computer  119 C and the sorting apparatus in order to determine location of a particular item or container. For example, scanning a container at computer  119 C as described below will signal to FO system  113  that the container has made it through picking zone  209  and now is physically located at the location of computer  119 C. In another example, scanning an item as described below will signal to FO system  113  that the item is at the location of computer  119 C and will be placed at the sorting apparatus shortly. In some embodiments, FO system  113  can use this information to trace movements of containers and the items therein through fulfillment center  200 . 
     Upon a successful identification of a sorting apparatus ID based on a user input or a signal from FO system  113 , computer  119 C may display initialization UI  600 C of  FIG.  6 C , another version of initialization UI  600 A with a workstation ID displayed in workstation ID input box  605  and a sorting apparatus ID displayed in sorting apparatus ID input box  606 . 
     In some embodiments, container pane  620  may now display an instruction to scan a container ID. In further embodiments, initialization UI  600 C may comprise a container/item ID input box  621  configured to receive a user input of a particular container ID of a container (e.g., container  323 A) or a particular item ID of an item from a container (e.g., container  323 A). The user may input the container or item ID by scanning an identifier (e.g., a barcode, an image, a Quick Response (QR) code, a text string, an RFID tag) on a container or an item using an input device (e.g., RFID reader, camera, or scanner) or entering the same using a manual input device (e.g., keyboard, mouse, virtual keyboard on a touchscreen). In some embodiments where the user inputted an item ID of an item from a container, computer  119 C may identify a container ID of the container by querying a database in FO system  113  that stores correspondence information between items and containers. 
     In some embodiments, auto assign toggle button  610  of  FIG.  6 C  may switch to an on-state, indicating that computer  119 C may assign a new container to the user. In one aspect, computer  119 C may assign the new container when the user completes sorting every item included in a container. Additionally or alternatively, computer  119 C may assign the new container when another worker (e.g., a manager of packing zone  211 ) transmits a signal to computer  119 C, via a networked system, in order to facilitate order fulfillment as a whole such as prioritizing a container that had been delayed. The user may opt to block such assignments by toggling the auto assign toggle button  610  to an off-state. 
       FIG.  7 A  is an exemplary embodiment of a sorting UI  700 A where the worker may begin a new sorting task. In some embodiments, sorting UI may be a version of initialization UI  600 A with a workstation ID and a sorting apparatus ID displayed in workstation ID input box  605  and sorting apparatus ID input box  606 , respectively, as well as information about a currently scanned container displayed in container pane  620 . Additionally or alternatively, message box  604  may be modified to display a message related to performance statistic of the user such as a number of units the user has scanned per hour (UPH), a total number of containers the user has scanned over a certain period of time, or the like. 
     In some embodiments, the information displayed in container pane  620  may comprise a container ID  722  corresponding to the current container, a batch ID  723  associated with the current container, and a remaining items text box  724  configured to display a number of items contained in the current container that remain to be scanned by the user. In some embodiments, container/item ID input box  621  of  FIG.  6 C  may be modified to container/item ID input box  721  of  FIG.  7 A , configured to display an instruction to scan an item ID of an item from the current container. The user may input the item ID by scanning an identifier (e.g., a barcode, an image, a Quick Response (QR) code, a text string, an RFID tag) on an item using an input device (e.g., RFID reader, camera, or scanner) or entering the same using a manual input device (e.g., keyboard, mouse, virtual keyboard on a touchscreen). 
     Upon a successful input of an item ID, computer  119 C may display sorting UI  700 B of  FIG.  7 B , which may be a version of sorting UI  700 A displaying item information related to the current container in container pane  620  and item information related to the current sorting apparatus in item pane  630 . 
     In some embodiments, container/item ID input box  721  may display an item ID associated with the currently scanned item input by the user. Some embodiments may display a full series of characters of the item ID in container/item ID input box  721 , but other embodiments may only display the last three digits of the item ID in order to allow quick visual comparison of the displayed item ID and the actual ID printed on the current item. Alternatively or additionally, container pane  620  may display a related item count  725 , which may be configured to display a number of the current item scanned thus far out of a number of the current item originally held in the current container. For example, “1/3” displayed in related item count  725  of  FIG.  7 B  indicates that there are three items in the current container corresponding to item ID “*************272” and that the currently scanned item is the first of the three. 
     In some embodiments, item pane  630  may display information related to the current item and its assigned location on the current sorting apparatus. The information may comprise a photo  731 , details  732  (e.g., name, SKU, and ID), and an assigned location  733  of the current item. Computer  119 C may determine assigned location  733  through the process described above with respect to  FIG.  5   . In some embodiments, displaying assigned location  733  as in  FIG.  7 B  may serve as an instruction for the user to place the current item at the assigned location. Alternatively or additionally, sorting UI  700 B may display or audibly announce an explicit message prompting the user to place the current item at the assigned location. 
     In some embodiments, item pane  630  may also display items in the current container that belong to the same order as the current item, as displayed in related item panes  734 A and  734 B. Related item panes  734 A and  734 B may be marked with the same location “A 02 ” as assigned location  733  of the current item, indicating that they belong to the same location. In some embodiments, one of the related item panes may correspond to the current item and be indicated as such by the emphasized border around related item pane  734 A. Although only two related item panes  734 A and  734 B are shown, the number is only exemplary and more or less item panes may be shown as appropriate. In some embodiments where there are too many related items to display, item pane  630  may also comprise navigation buttons  735 A and  735 B so that the user may browse other related items as desired. In the exemplary embodiment shown in  FIG.  7 B , however, related item panes  734 A and  734 B show only two of identical items, indicating that the order assigned to location A 02  comprises only two of the same items from the current container. It should be noted, however, that there may be other containers containing one or more items from the current order. 
     In some embodiments, computer  119 C may display the items in related item panes  734 A-B based on the item ID of the current item. More specifically, using the order ID identified as part of assigning a location for the current item, computer  119 C may retrieve a list of purchased item ID that correspond to items purchased as part of the current order. Computer  119 C may then retrieve container ID associated with each of the purchased item ID and extract any purchased item ID with an associated container ID that matches the current container ID. Once one or more matching purchased item ID are found, computer  119 C may assign assigned location  733  of the current item to the matching purchased item ID and display them in a corresponding number of related item panes  734 . 
     After the user has placed the current item at the assigned location, the user may scan another item in the current container, which would cause computer  119 C to display an updated set of information such as remaining items text box  724  displaying one less count (depicted in  FIG.  7 C ), a new item ID in container/item ID input box  721 , a new related item count  725 , a new set of photo  731 , details  732 , assigned location  733 , and related item pane(s)  734 . When the new item is a last item of an order, however, computer  119 C may display additional elements as shown in  FIG.  7 C . 
       FIG.  7 C  is an exemplary embodiment of sorting UI  700 C where the user has scanned all of the items included in an order. Sorting UI  700 C may be another version of sorting UI  700 B displaying updated information as well as the additional elements for indicating that the user has scanned all of the items included in an order. 
     In a first aspect, sorting UI  700 C shows a version of sorting UI  700 B where a next item scanned by the user is identical to the previous item. In some embodiments, this may be indicated by the same information shown in container/item ID input box  721  and item pane  630 , and updated information shown in remaining items text box  724  (one less) and related item count  725  (one more). 
     In a second aspect, sorting UI  700 C also shows a version of sorting UI  700 B where the second item is the last item of the order. In some embodiments, this may be noted by a completion mark  736 , indicating that the location assigned to the current item and the associated order, location A 02 , is complete (i.e., all purchased items of the order have been scanned and there is no other container holding an item associated with the order). 
     In other embodiments, sorting UI  700 D may display an announcement box  740 , as shown in  FIG.  7 D , announcing that the location assigned to the current item and the associated order, location A 02 , is complete and instructing the user to finalize the location. 
     In some embodiments, finalizing a location may comprise switching the location from an unfinalized state to a finalized state, which may comprise, for example, toggling a button on a sorting apparatus corresponding to the location, transmitting a signal via computer  119 C to change a state of an indicator associated with the location, manually moving the items placed at the location to another location, or the like. Regardless of the method, a finalized state may transmit a signal to a networked system to begin another operation on the items placed at the location. More specifically, switching the location to a finalized state may comprise modifying an automated indicator (e.g., an indicator light, a toggle switch, a lever) that signals another group of workers for packing the items (packers) or workstations associated with the packers to package the items placed at the location. 
       FIG.  7 E  is an exemplary embodiment of sorting UI  700 E where the user is instructed to finalize a particular group of locations. Sorting UI  700 E may be another version of sorting UI  700 D displaying announcement box  740 . In sorting UI  700 E, however, announcement box  740  may comprise a warning message  741 , communicating to the user that a particular group of locations need to be finalized because they will be closed; pending locations grid  742 , showing a group of locations that must be finalized; and a confirmation button  743 , prompting for the user&#39;s confirmation that he or she has finalized all of the locations shown in pending locations grid  742 . 
     In some embodiments, computer  119 C may display an announcement such as that shown in sorting UI  700 E when one or more orders assigned to one or more locations are determined to be substantially delayed. Such determination of substantial delay may be made by computer  119 C based on a period of time an order has been assigned to a location without being finalized by the user, by FO system  113  based on data gathered from other networked systems, or by a decision of another worker (e.g., a manager in charge of packing zone  211 ). In some embodiments, this determination may be based substantially on the location information collected every time a container or an item is scanned as discussed above. By gathering location information from each scan of an identifier and updating an associated location identifier with the location, FO system  113  may determine location of the scanned container or item. When collected and processed over time, this may allow FO system  113  to determine which containers (and items therein) are currently being sorted, which containers are on their way via transport mechanism  214 , and which are still being picked at picking zone  209 . In some embodiments, FO system  113  may use this information to determine that one or more containers are being delayed. Such processes of identifying delayed containers are described in U.S. patent application Ser. No. 16/299,619, entitled “System and Method for Computer-Implemented Split Shipping Communication Processes,” which is incorporated herein by reference in its entirety. 
       FIG.  7 F  is an exemplary embodiment of sorting UI  700 F where the user is instructed to continue scanning items after finalizing the orders. Sorting UI  700 F may be yet another version of sorting UI  700 D displaying announcement box  740 . In sorting UI  700 F, however, announcement box  740  may comprise an instruction prompting the user to continue sorting. 
     Furthermore,  FIG.  7 G  is an exemplary embodiment of sorting UI  700 G where the user is shown a notification that a particular location will be closed soon. Sorting UI  700 G may be yet another version of sorting UI  700 D displaying announcement box  740 . In sorting UI  700 G, however, announcement box  740  may comprise a notification that the location will be closed soon and an instruction to finalize the location as soon as possible. In some embodiments, closing a location soon may indicate that the order placed in the location is approaching a deadline or a time limit, after which the order will be considered delayed and ordered to be finalized as shown in  FIG.  7 E . Additionally or alternatively, item pane  630  may display an urgency mark  737  indicating that the particular location shown in assigned location  733  will close soon. 
     Similar to how the particular group of locations were determined to be substantially delayed in  FIG.  7 E , a determination that a particular location is approaching its deadline may be made by computer  119 C based on a period of time an order has been assigned to a location without being finalized by the user, by FO system  113  based on data gathered from other networked systems, or by a decision of another worker (e.g., a manager in charge of packing zone  211 ). 
     A version of sorting UI  700 G without announcement box  740  but with urgency mark  737  is shown in  FIG.  7 H  as sorting UI  700 H. As shown in  FIG.  7 H , completion mark  736  may appear simultaneously with urgency mark  737  in embodiments where, for example, the order assigned to the location shown in assigned location  733  is completed when the location had been determined to be approaching its deadline or time limit. 
       FIG.  8 A  is an exemplary embodiment of sorting UI  800 A displaying a consolidated list of tasks assigned to the user. Sorting UI  800 A may be a version of sorting UI  700 A when the user has selected task list button  607 . In some embodiments, sorting UI  800 A may display a consolidated list of tasks  810  comprising a table of information showing location (i.e., cell), batch ID, item name, item ID, container ID, and indications of the number of items processed currently and whether the location has been finalized. 
       FIG.  8 B  is an exemplary embodiment of sorting UI  800 B displaying a status of different locations on a sorting apparatus. Sorting UI  800 A may be a version of sorting UI  700 A when the user has selected finalized cell status button  608 . In some embodiments, sorting UI  800 B may display a finalized locations grid  820  showing a group of locations that has been finalized. In some embodiments, the user may refer to finalized locations grid  820  to confirm whether a location has been finalized yet.
