## Background
PRIORITY CLAIM
This U.S. patent application claims priority under 35 U.S.C. §119 to: Indian Patent Application No. 2339/CHE/2014, filed May 9, 2014. The aforementioned applications are incorporated herein by reference in their entirety.
TECHNICAL FIELD
This disclosure relates generally to systems and methods of operating systems, and more particularly to systems and methods for operating systems for integrating dynamic case management into a process management platform.
BACKGROUND
Conventional business process management (BPM) systems require significant resources to properly implement, manage, and execute BPM initiatives. Current BPM systems model initiatives as an ordered graph of events, which represent the activities performed for the BPM initiative, triggered by an event. This static approach sequesters scarce processing resources and fails to adapt to changing BPM needs. As BPM implementation scales up, the central coordination engine of this approach cannot withstand the increased load.

In another embodiment, a dynamic case management system includes one or more hardware processors and a computer-readable medium that stores instructions. When the instructions are executed by the one or more hardware processors, the one or more hardware processors to perform operations including creating, by one or more hardware processors, a plurality of lightweight stateless computing processes based on process definitions in a configuration file that correspond to an activity; placing the processes in a WAIT state; receiving a request to initiate a process instance corresponding to a lightweight stateless process; placing at least one of the processes in an EXECUTING state; processing the process instance by the processes placed in the EXECUTING state; determining a next process for the process instance; and routing the process instance to the next process.
In another embodiment, a non-transitory computer-readable medium stores instructions. When the instructions are executed by one or more hardware processors, the hardware processors perform operations. The operations include creating, by one or more hardware processors, a plurality of lightweight stateless computing processes based on process definitions in a configuration file that correspond to an activity; placing the processes in a WAIT state; receiving a request to initiate a process instance corresponding to a lightweight stateless process; placing at least one of the processes in an EXECUTING state; processing the process instance by the processes placed in the EXECUTING state; determining a next process for the process instance; and routing the process instance to the next process.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

DETAILED DESCRIPTION
Exemplary embodiments are described with reference to the accompanying drawings. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered as exemplary only, with the true scope and spirit being indicated by the following claims.
FIG. 1 illustrates an exemplary smart operating system according to some embodiments of the present disclosure. Smart operating system 100 may include three different computer hierarchical levels: User level 110, kernel level 120, and hardware level 130. The dichotomy of the levels may allow for each level to function independently while providing services to other levels.
User level 110 may include system call interface 111. User level 110 may allow a user to access smart operating system 100. System call interface 111 may perform standard system call functions, allowing a program to request a service from kernel level 120. System call interface 111 may provide hardware-related service (e.g., hard disk access), process creation services, and access to kernel service (e.g., process scheduling). Further examples of system calls facilitated by system call interface 111 may include read, write, close, wait, fork, exit, and kill. Other system calls are well known in the art and may be supported by system call interface 111. In this regard, system call interface 111 may operate as a membrane between kernel level 120 and user level 110. The specific implementation of system call interface 111 may be dependent upon the underlying hardware. In certain embodiments, system call interface 111 may operate using software interrupts to allow the transfer of control of kernel level 120.
Kernel level 120 may be divided into several subsystems, such as network management subsystem 121, file management subsystem 122, DCM subsystem 123, and hardware control 124. Network management subsystem 121 may allow kernel level 120 to allocate requests from an application to perform input-output operations on peripherals, such as network adapters. This may allow smart operating system 100 to register itself with, and communicate over, a network, such as a packet-switched network. File management subsystem 122 may allow access to the device's memory, accessing data and instructions. File management subsystem may be, for example, a NTFS file system, or another type of file system.
As shown, DCM subsystem 123 may have taken the place of the standard process management subsystem. The specifics of DCM subsystem 123 are discussed in more detail in relation to FIG. 2. Process management subsystems may be responsible for running and executing programs. Further, process management subsystems, such as DCM subsystem 123, may decide which programs should be allocated to the processor hardware and the sequence of the allocations.
Hardware level 130 may include hardware 131. Hardware 131 may include one or more processors, storage (e.g., RAM, ROM, hard disks), chipsets, and peripherals (e.g., network card, video card, mouse, keyboard, camera, microphone, etc.). Hardware 131 may interact with the subsystems of kernel level 120 via hardware control 124. Hardware 131 may include the hardware illustrated in FIG. 7 (e.g., processor 702, RAM 713, ROM 714, input device(s) 704, output device(s) 705, etc.).
FIG. 2 is a functional block diagram according to some embodiments of the present disclosure. System 200 includes DCM subsystem 210, which interacts with adaptive routing system (ARS) 230. DCM subsystem 210 includes process management system 211, state management system 213, observer 216, and network management system 217. These systems may interact to perform the objects of this disclosure.
Process management system 211 may include and manage lightweight autonomous processes 212. Lightweight autonomous processes 212 may be stateless processes that perform predefined operations independently. Process management system 211 may initiate lightweight processes based on previously defined process definitions which correspond to specific activities to be performed on different process instances. Process instances may be business process instances, corresponding to specific business procedures for business initiatives.
State management system 213 may include intelligent micro registries 214 and metadata store 215. Metadata store 215 may be a local or remote database. In an exemplary embodiment, metadata store 215 may include boot configuration data, which may provide process definitions for lightweight autonomous processes 212. For example, a process definition may specify a process type, process algorithms, failure handling mechanisms, input operations, output operations, triggers, or other rules. The boot configuration data may further provide default configurations to be initiated during system boot, such as how many lightweight autonomous processes to initiate for each type of activity. Other boot configuration data may include to put all lightweight autonomous processes 212 in a WAIT state or another state during boot. The boot configuration data of metadata store 215 may be managed by administrators using a configuration interface (e.g., a GUI).
Intelligent micro registries 214 may each correspond to an individual one of lightweight autonomous processes 212. Intelligent micro registries 214 may track and maintain the state of each lightweight autonomous process instance of lightweight autonomous processes 212. State management system 213 may maintain intelligent micro registries 214, which may also interact with observer 216 for runtime monitoring of each process and to determine the status of each process instance associate with each process, as well as any data used or produced by a process instance. In an exemplary embodiment, intelligent micro registries may be databases that are compatible with JavaScript Object Notation (JSON).
Observer 216 may track the state of various process including various process instances associated with them and the various activities that are performed at runtime. The tracking may be accomplished by querying intelligent micro registries 214 maintained by state management system 213 for each of the lightweight autonomous processes 212.
Network management system 217 may correspond to network management subsystem 121. Network management system 217 may include REST drivers 218 to enable each DCM node to connect and communicate with a central coordination system, such as Apache ZooKeeper, for example. REST drivers 218 may provide a flexible interface between applications and hardware. For example, applications or clients and the REST drivers may negotiate the communication protocol (e.g., HTTP, FTP, SOCKS, etc.) or the message format (e.g., XML, JSON, etc.). The application may communicate with REST drivers 218 during runtime. For example, applications may query REST drivers 218 for details of the functions that may be available in the underlying hardware. Network management system 217 may further connect with clusters of DCM nodes to scale horizontally or vertically based on the transactional load. By scaling DCM nodes in a decentralized manner, the core may be insulated from an individual node failure by transferring processes of the failed node to alternate nodes. Additional nodes may be added to address surges in demand.
Adaptive Routing System (ARS) 230 may connect to DCM subsystem 210 to provide routing services for each process instance, which may run on different nodes. ARS 230 may determine and route the process instances from one autonomous light weight process to another, based on the activity that corresponds to the lightweight autonomous process. To determine the next activity or lightweight autonomous process to route a process instance to, ARS 230 may use route-determination resources, such as artificial intelligence 231, complete event processing 232, rules engine 233, user interface 234, historic decision path analyzer 235, or pattern matching 236, for example. In an embodiment, multiple of the route-determination may be used in combination.
Artificial intelligence 231 may statistical methods and computational intelligence to mimic human perception and manipulation of the process instances. Complex event processing 232 may track and analyze data from multiple sources about past events to infer patterns for various process instances and activities or lightweight autonomous processes. Complex event processing 232 may gather information from intelligent micro registries 214, observer 216, metadata database 251, runtime database 252, archive database 253, or from sources over the Internet, such as the cloud and public databases. Rules engine 233 may utilize pre-defined rules to determine where to route a process instance. These rules may be simple, such as basic logic statements, or more complex derivations including numerous variables.
User interface 234 may utilize human input via a runtime execution graphical user interface (GUI) to manipulate routing decisions. A runtime execution GUI may enable a user or a group of users to view the runtime state of each lightweight autonomous process and each process instance. Runtime execution GUI may also receive input from a user or group of users, translate the input, and transmit the input to ARS 230. For example, a runtime execution GUI may show a list of the lightweight autonomous processes and relevant information, such as the queue size, status, and the type of activity that the lightweight autonomous process corresponds to. Further, a runtime execution GUI may sort a list of lightweight autonomous processes by queue size. A runtime execution GUI may also receive input for a user directing process management system 211 to create additional lightweight autonomous processes to perform the activity of the lightweight autonomous process with the largest queue. In other embodiments, user interface 234 may simply be a prompt that receives a confirmation for a specific course of action previous calculation using other route-determination resources. In other embodiments, the user may be presented with multiple options to pick from, or may directly decide how individual process instances may be routed. In other embodiments, user interface 234 may include a human user's ability to override current routing functions to correct erroneous routing or prioritize process instances of high importance.
Historic decision path analyzer 235 utilizes past data to derive what routing decision was most utilized in previous routing determinations. Historic decision path analyzer may utilize information from intelligent micro registries 214, observer 216, metadata database 251, runtime database 252, archive database 253, or from sources over the Internet. Pattern matching 236 may utilize tree structures or sequences to determine if a perceived sequence or routing decision constitutes a pattern. Pattern matching 236 may identify patterns of activities that are heavily used by processes to determine improved routing and resource balancing of lightweight autonomous processes.
Metadata database 251 may be a persistence unit, such as a database or file system, that stores all the core lightweight autonomous process definitions, associated rules, tasks, jobs, scheduling information, security, and other associated context information. Metadata database 251 may assist in managing and executing the processes and managing the DCM scenarios.
Runtime database 252 may be a main persistence unit, such as a database, that stores the dataset for various process instances. It may include all of the instance data for various processes.
Archive database 253 may be a persistence unit, such as a database, that stores all of the archived datasets for various processes. In an embodiment, when runtime database 252 exceeds a limit in size or when data in runtime database 252 exceeds an age limit, the data of runtime database 252 may be transferred from runtime database 252 to archive database 253, to maintain historical data, which may be used for future reference or compliance reasons. The size limit may be pre-defined based on user preferences or compliance regulations. In other embodiments, the size limit may be derived from the available storage in runtime database 252. The age limit may also be set based off of user preferences or compliance regulations.
FIG. 3 depicts a flow diagram illustrating an exemplary dynamic case management (DCM) subsystem process in accordance with some embodiments of the present disclosure. Process 300 may begin with step 301, which may spawn lightweight autonomous processes based on process definitions during boot up. Step 301 may be described in more detail in FIG. 4.
FIG. 4 is a flow diagram illustrating an exemplary lightweight process management process in accordance with some embodiments of the present disclosure. Process 400 may begin with step 402, during which process management system 211 may request process definitions, stored in metadata store 215, from state management system 213. At step 404, process management system 211 may receive the boot configuration file or the associated data, which includes process definitions from state management system 213. The process definitions may express the activity associated with the process, including the quantity of lightweight autonomous process that should be spawned for each type of activity. At step 406, process management system 211 may create the lightweight autonomous process according the boot configuration data received in step 404. At step 408, process management system 211 may place the lightweight autonomous processes 212 in a WAIT state. This may happen as each lightweight autonomous process is created or all at once when all the lightweight autonomous processes have been created.
At step 410, each lightweight autonomous process may listen for PI data. In certain embodiments, after a predetermined amount of time has passed without receiving any PI data, a lightweight autonomous process may be placed in a hibernation state. Further, a lightweight autonomous process may be shut down based on a predetermined about of time spend in a hibernation state or in a WAIT state. This may allow process management system 211 to allocate processing resources based on the demands of the active process instances.
At step 412, a lightweight autonomous process may receive PI data. The PI data may correspond to the activity that the lightweight autonomous process performs. At step 414, the lightweight autonomous process may transition to an EXECUTING state, responsive to receiving the PI data in step 412.
At step 416, consecutive requests, including data for additional PIs, may be queued for subsequent processing. In an exemplary embodiment, process management system 211 may track the status of the queue for each of the lightweight autonomous processes and may create additional lightweight autonomous processes based on the process definition of a particular activity, when the queues for processes of that activity are all full or overburdened. In an exemplary embodiment, the queue may function as a first-in-first-out (FIFO) queue. Other queuing techniques, such as last-in-first-out (LIFO), may be used to carry out the objects of this disclosure depending upon the user preferences.
At step 418, the lightweight autonomous, which may now be in the EXECUTING state, may process the PI data. For example, the lightweight autonomous process may perform the corresponding activity on the PI using the PI data. At step 420, once the processing is complete, the PI may be routed to another lightweight autonomous to perform a different activity for the PI, based on the routing information from ARS 230.
At step 422, the lightweight autonomous process may check to see if its queue is empty. If there are pending requests in its queue, the lightweight autonomous process may receive the PI from its queue and, at step 418, process the PI. When there are no pending requests in its queue, the lightweight autonomous process may revert to the WAIT state, at step 408. In other embodiments, the lightweight autonomous process may be placed in a hibernation state or be shut down when its queue is empty.
Returning to FIG. 3, at step 302, the PI may be transitioned from one lightweight autonomous process to another. An embodiment of step 302 is described in more detail in FIG. 5.
FIG. 5 is a flow diagram illustrating an exemplary Process Initiative (PI) routing process in accordance with some embodiments of the present disclosure. At step 502, ARS 230 may determine an initial path for a PI through various lightweight autonomous processes. This path may be based on the objects of the PI and may utilize the same lightweight autonomous process multiple times.
Next, at step 504, ARS 230 may modify the path based on runtime data. This may take place when a PI has completed a particular lightweight autonomous process, such as in step 420. However, in certain embodiments the path may be modified based on other activity in a particular node or demand levels for various activities of the lightweight autonomous processes. For instance, the sequence of activities for a particular PI may be altered when the next activity the initial process path has an overburdened queue. In other embodiments, the path of the PI may be altered to route the PI to a lightweight autonomous process that has an empty queue, is in a WAIT state, or is in a hibernation state. Other modifications to the PI process path based on load balancing, efficiency, and user priorities.
At step 506, the PI may be transitioned to the next lightweight autonomous process on the modified path. This may occur as described in step 420. Then at step 508, ARS 230 may determine whether the process path for the PI is complete. In certain embodiments, if all processing necessary for a PI is completed, the routing process may end for the PI. Otherwise, process 500 may revert to step 504, where the path may be modified from further runtime data. In certain embodiments, PIs may have pre-determined lifespans, or may be ongoing and never end.
Returning to FIG. 3, following step 302, at step 303, state management system 213 may monitor the activity of each PI. State management system 213 may further record the process history of each PI, such as each lightweight autonomous process that acts on the PI. Step 303 is described in more detail with regard to FIG. 6.
FIG. 6 depicts a flow diagram illustrating an exemplary PI tracking process in accordance with some embodiments of the present disclosure. At step 602, process 600 may begin with state management system 213 creating intelligent micro registries 214 for each PI. The intelligent micro registry creation may be performed responsive to the PI being first received at the node. In other embodiments, an intelligent micro registry may be created when a PI is first acted on by a lightweight autonomous process.
At step 604, the intelligent micro registry for a PI may determine that the PI has transitioned between lightweight autonomous processes, such as in step 420 or step 506, for example. At step 606, the intelligent micro registry may be updated based on the transition to include the lightweight autonomous process history, including, for example, the activities performed on the PI, a timestamp, a state of the PI, any variables of the PI that may have been altered, an identifier of the lightweight autonomous process, and an identifier of the node. Other events may trigger intelligent micro registry updates, such as errors that may occur when certain processes are performed or routing changes that may significantly alter the process path. For example, intelligent micro registries may note that a certain activity was performed out of conventional order because the process path was altered due to an overwhelming demand for the otherwise conventional activity at that time.
At step 608, state management system 213 or the corresponding one of intelligent micro registries 214 may determine whether the PI is still active. If the PI has completed and no longer is being processed or pending processing by a light weight autonomous process, such as if the PI process path is complete in step 508, process 600 may end, and the intelligent micro registry for the PI may stop monitoring the PI. In certain embodiments, the intelligent micro registry data may be archived as well. However, when it is determined that the PI is still active at step 608, process 600 may revert to step 604, determining if the PI has transitioned between lightweight autonomous processes.
