Title: Systems and methods for automated delivery worker scheduling

Description:
TECHNICAL FIELD 
     The present disclosure generally relates to computerized systems and methods for automated delivery worker scheduling. In particular, embodiments of the present disclosure relate to inventive and unconventional systems for forecasting a number of sold units, determining a number of parcels required for delivery of the sold units, and automatically determining an optimum delivery worker schedule for delivery of the determined number of parcels. 
     BACKGROUND 
     Numerous computerized inventory management systems and delivery centers exist. These systems and centers are designed to enable efficient distribution of goods in an established delivery area and to utilize available resources for delivering these goods to consumers, for example, at local shipping centers. Traditionally, each delivery center may divide its established delivery area into separate regions, and then these systems may direct delivery workers to deliver the goods to one or more of the regions. 
     Typically, however, each region is only covered by a single delivery worker, who may be unable to keep up with a region&#39;s delivery demands. Further, conventional systems are unable to dynamically adjust regional assignment of delivery workers. Moreover, conventional systems are often not able to flexibly cope with a dynamic or changing delivery or sales forecast. Nor are they equipped to analyze a delivery vehicle&#39;s load limit or consider a delivery worker&#39;s delivery efficiency or skill. 
     Even further, numerous computerized inventory management systems include one or more administrators in charge of manually assigning delivery workers to deliver packages, which may add to an increase in delivery time and may result in delivery inefficiencies. Such administrator-based systems often times fail to accurately account for the required number of packages or parcels that need to be delivered. 
     Therefore, what is needed is a system that is capable of dynamically determining an optimum delivery worker schedule for timely and accurate delivery of a required number of parcels. Further, what is needed is a digital delivery solution that can quickly and flexibly handle unpredictable changes based on changes in sale forecasts and available delivery men resources. Finally, what is needed are improved methods and systems for facilitating reassignment of delivery workers from one area to another in order to accommodate geographic and cyclical changes in sales forecasts. 
     SUMMARY 
     One aspect of the present disclosure is directed to a system for automated delivery worker scheduling. The system may include at least one processor; and at least one non-transitory storage medium comprising instructions that, when executed by the at least one processor, cause the at least one processor to perform steps. The steps may include receiving a forecasted number of sold units for a first period of time; receiving a unit per parcel rate associated with a plurality of camps; determining a number of parcels for the plurality of camps based on the forecasted number of sold units and the respective unit per parcel rate; determining forecasted attendance information for the plurality of camps; determining a number of delivery workers based on the forecasted attendance information and the number of parcels; and assigning a plurality of the parcels to the determined delivery workers. 
     Another aspect of the present disclosure is directed to a method for automated delivery worker scheduling. The method may include receiving a forecasted number of sold units for a first period of time; receiving a unit per parcel rate associated with a plurality of camps; determining a number of parcels for the plurality of camps based on the forecasted number of sold units and the respective unit per parcel rate; determining forecasted attendance information for the plurality of camps; determining a number of delivery workers based on the forecasted attendance information and the number of parcels; and assigning a plurality of the parcels to the determined delivery workers. 
     Yet another aspect of the present disclosure is directed to a system. The system may include a memory storing instructions; and at least one processor configured to execute the instructions to perform operations. The operations may include receiving a forecasted number of sold units for a first period of time; receiving a unit per parcel rate associated with a plurality of camps; determining a number of parcels for the plurality of camps based on the forecasted number of sold units and the respective unit per parcel rate; determining forecasted attendance information for the plurality of camps; determining a number of delivery workers based on the forecasted attendance information and the number of parcels; determining the number of delivery workers is insufficient for delivery of the number of parcels to at least a first camp; reassigning a fixed number of delivery workers from a second camp to the first camp; assigning, based on the reassignment, flex delivery workers to the first camp; and assigning a plurality of the parcels to the reassigned and flex delivery workers. 
     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 systems and methods configured for automating delivery worker scheduling including automatically determining an optimum delivery worker schedule for delivery of a required number of parcels in a particular delivery area. 
     Referring to  FIG. 1A , 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. 1A , 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 , warehouse 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. 1B, 1C, 1D, and 1E , 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. 1B ), a Single Detail Page (SDP) (e.g.,  FIG. 1C ), a Cart page (e.g.,  FIG. 1D ), or an Order page (e.g.,  FIG. 1E ). 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. 1B ) 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. 1C ) 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. 1D ). 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. 1E ) 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 warehouse 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. 
     Warehouse 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  119 B, 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. 1A  is an example only. For example, while  FIG. 1A  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. 1A . 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. 1A  indicating that item  202 A has been stowed at the location by the user using device  1196 . 
     Once a user places an order, a picker may receive an instruction on device  1196  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. 
       FIGS. 3-5  depict diagrammatic illustrations of an exemplary automated delivery worker (DW) process  300 , consistent with the disclosed embodiments. As shown in  FIG. 3 , delivery worker process  300  may be shown in matrix form and may be divided into different stages or phases. Delivery worker (DW) process  300  may include a planning phase  302 , a schedule phase  304 , and an operation phase  306 . As shown in  FIG. 3 , planning phase  302  may include planning for a forecast  308  based on a forecast calculation. 
     Shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS) may generate, based on a received actual number of units, a number of parcels received, and a unit per parcel rate, a forecast calculation for forecast  308 . The forecast calculation may include a first multiplication of a number of parcels received, by the unit per parcel rate to determine a forecast for an anticipated number of units that may be delivered relative to available parcels during a particular time period. The result of the first multiplication may then be compared to the received number of units sold to determine forecast  308 . 
     For example, in an exemplary embodiment, 500 units may be sold and a unit per parcel rate of 5 stock keeping units (SKUs)/1 parcel may be received. Unit per parcel rate may reflect how many items are included in each package (on average). These values may subsequently be multiplied by each other resulting in 100 parcels required for delivery. Subsequently, in other embodiments, systems  101 ,  107 ,  117 , and  125  may next compare a calculated or forecasted number of parcels (e.g. 100 parcels) to a received indication of a number of parcels received during an initial time period for a camp. Where the calculated or forecasted number of parcels (e.g. 100 parcels)exceeds the result of the indication of a number of parcels received during an initial time period for a camp, systems  101 ,  107 ,  117 , and  125  may only deliver the number of parcels received during the initial time period for a camp (e.g. since less than 100 parcels are available for delivery). Alternatively, where the calculated or forecasted number of parcels (e.g. 100 parcels) is determined as less than the result of the indication of a number of parcels received during an initial time period for a camp, systems  101 ,  107 ,  117 , and  125  may deliver the full calculated or forecasted number of parcels (e.g. 100 parcels) for the camp (e.g. since more than the required 100 parcels are available for delivery) s). Other forecast calculation methodologies comparing a received actual number of units, number of parcels received, and unit per parcel rate, may be contemplated 
     Consistent with this disclosure, a forecast calculation may be further based on the camp-level capacity. Camp-level capacity may reflect an upper threshold number of units that may be sold and delivered to a camp during an identified time period. Similarly, a camp may be associated with a camp-level capacity. Further, a camp may be associated with a first set of postal codes, and an actual number of units sold may comprise a number of units associated with a plurality of camps. While a forecast of a number of parcels may be generated based on three factors: units sold, units per parcel (e.g. how many boxes will be needed), and camp coverage (how many boxes arrived at a camp), additional factors may be included in a forecast calculation. For example, each camp team may further input a forecast value at a graphical user interface (GUI), and any of systems  101 ,  107 ,  117 , and  122  may receive volume related information. Other forecast calculation methodologies may be contemplated in order to generate delivery worker (DW) process  300  and forecast  308  as shown in  FIG. 3 . 
     As further shown in  FIG. 3 , planning phase  302  of delivery worker (DW) process  300  may include planning for forecast  308 , forwarding forecast  308  at time  310 , and forwarding forecast  308  at time  312 . As shown in  FIG. 3 , delivery worker process  300  may be based on a weekly calculation of delivery worker schedules. However, other embodiments based on other time periods are possible as well. Forecast  308  may constitute an exemplary 6-week forecast  314 . Exemplary 6-week forecast  314  may begin on a Tuesday, but other starting days during the week may be contemplated. Forecast  308  may also include an input forecast which may include a sales forecast, an inbound forecast, and an outbound forecast. Forecast  308  may also be a fixed forecast  316  or a dynamic forecast  318 . A fixed forecast may remain static and a dynamic forecast may be changed based on input values, such as a preferred starting day or a preference in forecast duration. 
     In some embodiments, as shown in  FIG. 3 , SCM  117  may forward the forecast  308  at time  310 . SCM  117  may incorporate sales and operation planning (S&amp;OP) data at step  320  and include forecast integration data to SAT  101  at time  312 . At step  322 , SCM  117  may also forward other sales planning data  322  relating to fixed forecast  316  as well as other sales planning data  324  relating to dynamic forecast  318  at time  312 . At time  312 , SAT  101  may calculate an estimate 326 of camp parcels for fixed forecast  316  and may also calculate an estimate 328 of camp parcels for dynamic forecast  318 . Estimate 326 may include a number of camp parcels estimated on Wednesday and Friday. Estimate 328 may also include a number of camp parcels estimated 334 on Monday and Wednesday. Other estimated days may be used for forecasting. S&amp;OP planning information and manufacturing information including unit per parcel (for example, for an exemplary time period of 2 weeks) and camp coverage information (relating to each camp forecast, fixed and dynamic) may be contemplated. 
     As shown in  FIG. 4 , delivery worker (DW) process  300  may further include transportation system (TDM)  107  for executing an algorithm to perform forecasting and scheduling operations. TDM  107  may receive information from SCM  117  and SAT  101  and may perform an algorithm to further refine forecast calculation for forecast  308 . At time  402 , TDM  107  may include DW schedule planning based on an input from one or more delivery workers. An algorithm (as further discussed below with reference to  FIGS. 8-10 ) may also conduct a DW Resource and parcels forecast  406  as part of scheduling  304  and may also determine a DW working schedule  410 , both of which may be provided as inputs  408  and  412  to TDM  107  for enhancing scheduling  304 . As shown in  FIG. 4 , TDM  107  may also provide as an input schedule status  414  and insert values relating to delivery worker days off  416 . 
     In some embodiments, an algorithm may be optimal handling of a specific volume arrival pattern for camps, where the volume may be highest on Tuesdays and Wednesdays, while being lowest on Saturdays and Sundays. In some scenarios, a volume may be highest at the start of the month. In other scenarios, there may also be unfair delivery worker day off scheduling, where day offs may be scheduled manually at the individual or group level. Weekend days may be typically preferred by most delivery workers and day offs may be assigned based on priority. Therefore, an algorithm (as discussed with reference to  FIGS. 8-10  below) may be used. Furthermore, promised Delivery Date (PDD) misses may also be caused by delivery capacity shortage, and PDD misses may be caused on days where the volume spikes when there are not enough delivery resources available. A waste of unused delivery workers or deliver resources may also be generated on days with low volumes. Accordingly, in view of the changes in volume, an algorithm may be used to assign delivery work days off in line with a volume forecast and/or to calculate a delivery capacity based on a delivery worker count scheduled to work in order to help respond to potential issues ahead of time (as further discussed with reference to  FIGS. 8-10 ). 
     As shown in  FIG. 5 , LMS  125 , HR (a Human Resources process, also performed by LMS  125 ), and an operation (performed by device  107 A) may perform further processes. At time  502 , operation  107 A may input schedule information at subsystem  502  where a user could use a device (e.g.,  107 A) to input a desired work schedule, including holidays. At subsystem  508 , employment information and camp information may send at step  510 . DW Management information including DW schedule information, attendance management information, and HR employee information may also be inputted by LMS  125 . Attendance management information may include a delivery worker&#39;s schedule, clock-in and clock-out time information, and employee information (e.g., name, phone number, employee records). At subsystem  512 , leave information and reinstatement information may also be sent at time  516  to HR subsystem  514 . At subsystem  518 , LMS  125  may perform updating a DW working schedule. To update, LMS  125  may force a periodic “push” or “pull” responsive to update(s) made at  518 , and/or any other known means of communication or synchronization. LMS  125  may also act as a data source that operation ( 107 A) may periodically receive data from. In other embodiments, LMS  125  may send a day on/off  522  command to subsystem  524  which may update the DW working schedule. In other embodiments, subsystem  524  may further provide a DW mobile application which may allow for manual control for updating a DW working schedule and which may allow for a manual input update of delivery worker off days (according to day on/off command  522 ). At subsystem  520 , operation performed by device  107 A may further provide a DW working schedule update for administering a schedule. Other steps and operations now shown for updating a DW working schedule may be contemplated consistent with this disclosure. 
       FIG. 6  depicts a diagrammatic illustration of the overall performance of the entire forecast calculation  600 , consistent with the disclosed embodiments. As shown in  FIG. 6 , an exemplary calendar for the month of October 2018 is displayed and shows the overall performance of the entire forecast calculation  600 . On a daily basis  602 , numerous metrics are tabulated. These metrics include a number of boxes (i.e. how many parcels went through the forecast calculation on that day), a number of delivery workers (DW) in attendance, a number of walking delivery workers (DW) in attendance, a number of overtime workers (i.e. a number of hours that were worked overtime in the forecast calculation) and a rate of delivery worker (DW) attendance. Walking delivery workers may include only delivery workers that walk to make deliveries as opposed to driving delivery workers that drive to a location to make a delivery. Often times, walking delivery workers may be paired with driving delivery workers for a particular delivery. 
     As shown in  FIG. 6 , these metrics may vary on a daily basis or may stay the same over time. Weekly Total 604 aggregates may be calculated for the week. Other metrics and statistics may be calculated and displayed on a calendar. 
       FIG. 7  is a flow chart illustrating an exemplary process for automating delivery worker scheduling, consistent with the disclosed embodiments. While the exemplary method  700  is described herein as a series of steps, it is to be understood that the order of the steps may vary in other implementations. In particular, steps may be performed in any order, or in parallel. Moreover, while shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may perform the following steps, it is to be understood that systems  101 ,  107 ,  117 , and  125  may operate separately or may work together collectively in any manner to perform the following steps. 
     At step  702 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may receive a forecasted number of sold units for a first period of time. Shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may include determining forecasted attendance information for a set of delivery workers and may assign the plurality of the parcels to the determined delivery workers. This may include assigning the plurality of parcels based on the determined historical attendance information. Historical attendance information may be stored in a database or in memory. In an exemplary embodiment, transportation system  107  may search a database or memory for attendance information and may compare attendance information between a plurality of delivery workers. Transportation system  107  may also compare attendance information against a predetermined threshold value. Where transportation system  107  determines the attendance of a particular worker fails to exceed a predetermined threshold, system  107  may not assign a plurality of the parcels to the delivery worker. However, where transportation system  107  determines the attendance of a particular worker exceeds a predetermined threshold, transportation system  107  may assign a plurality of the parcels to a delivery worker. Multiple predetermined threshold values may be contemplated for evaluating delivery worker attendance. 
     At step  704 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may receive a unit per parcel rate associated with a plurality of camps. At of the plurality of camps may be associated with a camp-level capacity and a camp-level efficiency. A unit per parcel rate may be stored in any of shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  and may further determined by dividing the received number of units sold by the received number of parcels. At step  706 , any of systems  101 ,  107 ,  117 , and  125  may determine a number of parcels for the plurality of camps based on a forecasted number of sold units and the respective unit per parcel rate. A number of parcels for the first camp may further based on the associated camp-level capacity and camp-level efficiency. Other methods for determining a number of parcels for a plurality of camps may be contemplated. 
     At step  708 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may determine forecasted attendance information for a plurality of camps. Any of systems  101 ,  107 ,  117 , and  125  may determine the forecasted attendance rate based on receiving, from a mobile device associated with at least one delivery worker, vacation or absence information for the first time period. This data may be compared against other attendance data where a delivery worker was not on vacation or absent. 
     At step  710 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may determine a number of delivery workers based on the forecasted attendance information and the number of parcels. The determined delivery workers may include permanent delivery workers. The plurality of delivery workers may comprise delivery workers, walking delivery workers, and driving delivery workers. 
     At step  712 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may assign a plurality of the parcels to delivery workers. The assigning may include assigning fewer than the plurality of parcels to the permanent delivery workers, determining a difference between the plurality of the parcels and the assigned plurality of parcels to determine a number of deliverable parcels, determining a number of temporary delivery workers, and assigning the deliverable parcels to the temporary delivery workers. Assigning a plurality of the delivery workers may further comprise assigning based on individual target efficiency values for each delivery worker. Further, assigning based on individual target efficiency values may include assigning to reduce overtime or comply with a rule. 
       FIGS. 8-10  are flow charts illustrating exemplary processes for a scheduling algorithm, consistent with the disclosed embodiments. While the exemplary methods  800 ,  900 , and  1000  are described herein as a series of steps, it is to be understood that the order of the steps may vary in other implementations. In particular, in certain embodiments, steps may be performed in any order, or in parallel. Moreover, while shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may perform one or more of the steps depicted in  FIGS. 8-10 , it is to be understood that systems  101 ,  107 ,  117 , and  125  may operate separately or may work together collectively in any manner to perform the following steps. 
     At step  802 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may begin an algorithm process that starts scheduling for a delivery worker. As shown in  FIG. 4 , delivery worker (DW) process  300  may include transportation system (TDM)  107  executing an algorithm to perform forecasting and scheduling operations. TDM  107  may receive information from SCM  117  and SAT  101  and may perform the algorithm process that starts scheduling for a delivery worker to further refine forecast calculation for forecast  308 . TDM  107  may perform DW schedule planning based on an input from one or more delivery workers. 
     At step  804 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may collect forecast parcel data (as shown in  FIG. 9 ). 
     At step  902 , systems  101 ,  107 , or  125  may start to collect forecast parcel data, and at step  904 , may receive a units sold forecast from SCM  117 . The unit sold forecast may be calculated based on historical data and may be adjusted manually for products whose sales volume is projected to increase following a sales promotion. At step  906 , in some embodiments, systems  101 ,  107 ,  117 , and  125  may receive and calculate a unit per parcel (UPP). UPP may be calculated based on historical data and may be changed frequently as forecasts may changed once every 2-3 weeks. At step  908 , in some embodiments, systems  101 ,  107 ,  117 , and  125  may calculate each camp&#39;s parcel coverage based on a share of zipcodes covered by the camp. Coverage may be defined as the number of zipcodes assigned to each camp divided by the number of all zip codes in a certain geographical area. At step  910 , in other embodiments, systems  101 ,  107 ,  117 , and  125  may calculate each camp&#39;s parcel coverage by a shift or a time period of work. Shift-level parcel coverage may be defined by the percentage of volume covered by a shift (or working time period) at each camp. All camps may have their own shift (or working time period) schedule (e.g. 9 am to 5 pm). Shift-level parcel coverage may be calculated based on historical data. At step  912 , in some embodiments, systems  101 ,  107 ,  117 , and  125  may calculate an estimated parcel count according to a formula where a camp&#39;s shift parcels=forecasted number of units sold ( 904 )/unit per parcel rate ( 906 )*camp parcel coverage ( 908 )*shift parcel coverage of camp ( 910 ); in other embodiments, the parcel count may be based on any of the foregoing values (units sold, UPP, a camp parcel coverage, coverage by shift, etc.). 
     At step  806 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may collect metadata for delivery capacity calculation. In some embodiments, delivery capacity may refer to an amount of volume that can be delivered. In some embodiments, delivery capacity may equal a target parcel per day (PPD) multiplied by a personal weight. In some embodiments, target PPD may refer to a number of parcels that 1 delivery worker may aim to deliver in a day. In other embodiments, a target PPD may differ by day, camp, and camp shift. In some embodiments, a personal weight of 1.0 may apply if a delivery worker with more than 6 weeks experience makes deliveries the whole day. In other embodiments, different personal weights may be assigned to individuals depending on the number of weeks into the job. For example, new hires who have are 0-1 weeks experience onto the job may be assigned a weight of 0.0. Delivery work may not be assigned to new hires in their 1St week as the week is for new employee orientation including training sessions for delivery operations. In another example, new hires who are in weeks 1-2 may be assigned a weight of 0.5. However, on other embodiments, new hires in their second week may deliver only half of the target volume. In other embodiments, personal weights may vary based on work type. For example, weight assigned to delivery worker may be normalized at a value of 1.0. As another example, weight assigned to delivery workers delivering after sorting according to categories of morning, lifter, or sorter may be assigned at 0.5 weight. Weight assigned at delivery workers delivering to support another camp aside one&#39;s own may be assigned a value of 0.7 weight. Other weight value assignments may be used in some embodiments. 
     At step  808 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may collect delivery worker base schedules. In some embodiments, base schedules pertain to annual leave, other leave types (maternity leave, alternative leave, reward vacation, official leave), and leave of absence (paid leave, unpaid leave, suspension). In some embodiments, delivery workers to whom off-days are to be assigned may be determined based on a base schedule that is collected and delivery capacity may be calculated according to the base schedules. 
     At step  810 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may collect a delivery worker&#39;s preferred day off. In some embodiments, systems  101 ,  107 ,  117 , and  125  may collect the preferred days off from the delivery workers. A preferred off-day is a value referred to when assigning days off to a delivery worker. The delivery worker&#39;s preference may be a factor in the algorithm but is not a requirement. In some embodiments, systems  101 ,  107 ,  117 , or  125  may check whether delivery workers have been assigned off days on days of their preference in the most recent four weeks and may prioritize assigning off-days on preferred days for delivery workers who were least likely to be assigned a day off on the days of their preference. 
     At step  812 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may calculate camp delivery capacity. In some embodiments, camp delivery capacity may equal the sum of each active delivery worker&#39;s delivery capacity. In some embodiments, active delivery workers may pertain to available manpower, specifically to those delivery workers who report to work at a camp and make deliveries. In some embodiments, systems  101 ,  107 ,  117 , and  125  may calculate the delivery capacity by camp and by group within each camp and estimate any shortage or excess in delivery worker resources against a parcel count forecast. 
     At step  814 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may assign a delivery work schedule  1000 . As shown in  FIG. 10 , at step  1002 , systems  101 ,  107 ,  117 , and  125  may start to assign a delivery work schedule. At step  1004 , systems  101 ,  107 ,  117 , and  125  may assign 2 days off per week. From the 2 days off, systems  101 ,  107 ,  117 , and  125  may assign 1 day off to a preferred day and may assign the other day off randomly. In some embodiments, for delivery workers working 6 days a week, systems  101 ,  107 ,  117 , and  125  may schedule a day off based on preference. At step  1006 , in other embodiments, systems  101 ,  107 ,  117 , and  125  may calculate a camp&#39;s delivery capacity for each day including for an assigned off day. At step  1008 , in other embodiments, systems  101 ,  107 ,  117 , and  125  may find the day with the lowest and highest delivery capacity against a forecasted parcel count. The days with the lowest and highest delivery capacities may be calculated by subtracting the delivery capacity from the parcel count forecast. At step  1010  other embodiments, systems  101 ,  107 ,  117 , and  125  may find delivery workers who are off on the day when the delivery capacity is lowest while they are scheduled to work on the day when the delivery capacity is highest. This may be performed to find delivery workers who are off on days when there are not enough delivery workers and to have them report to work on those days. At step  1012 , in some embodiments, systems  101 ,  107 ,  117 , and  125  may switch the day off schedule of the delivery worker. This may include swapping the delivery worker schedule on the day with the lower delivery capacity with the schedule on the day with the highest delivery capacity. At step  1014 , i other embodiments, systems  101 ,  107 ,  117 , and  125  may remove the day with the lowest delivery capacity from the target days for delivery schedule assignment. At step  1016 , in other embodiments, systems  101 ,  107 ,  117 , and  125  may determine if all days are removed from the target days for delivery schedule assignment, and if so, may terminate at step  1018  the scheduling program performed by the processor. 
     At step  816 , shipment authority technology system (SAT)  101 , transportation system  107 , supply chain management system (SCM)  117 , and/or labor management system (LMS)  125  may notify a schedule to a delivery worker&#39;s punch application. The notification may take the form of an alert, email, or electronic message to communication to an application, consistent with this disclosure
