(Configuration of business process simulator 310)
FIG. 3 is a block diagram of business process simulator 310 in the first embodiment. The configuration of the business process simulator 310 will be described with reference to FIG. In FIG. 3, the business process simulator 310 includes a process definition storage unit 311, a process definition input unit 312, a resource definition storage unit 313, a resource instance storage unit 314, a resource instance input unit 315, and a simulation execution unit 316.

(Function of component)
The function of each component of the business process simulator 310 will be described.
(1) The process definition storage unit 311 stores business process definitions. The “business process definition” is information including “business process” and “resource setting information” of resources necessary for executing each task constituting the business process. This “business process definition” will be described later.
(2) The process definition input unit 312 provides a user with a function of inputting “business process” and “resource setting information”. The process definition input unit 312 outputs the “business process definition” generated from the “business process” and “resource setting information” input by the user to the process definition storage unit 311 and stores them.
(3) The resource definition storage unit 313 stores resource definitions that are the types of resources that can be used in the simulation.
(4) The resource instance storage unit 314 stores “resource instances”, which are information on all available resource instances that exist in the simulated world.
(5) The resource instance input unit 315 provides a user with a function of inputting a resource instance. The resource instance input unit 315 stores the “resource instance” input by the user in the resource instance storage unit 314.
(6) The simulation execution unit 316 executes simulation using “business process definition”, “resource definition”, and “resource instance”.
(7) In the business process simulator 310 of FIG. 3, in the input using the process definition input unit 312 and the resource instance input unit 315, the input is performed using the input device of the mouse 815 or the keyboard 814 shown in FIG. The input screen is displayed on the display device 813 (not shown in FIG. 3). The user inputs to the process definition input unit 312 and the resource instance input unit 315 using the input device and the display device. Further, as will be described later, a warning issued by the process definition input unit 312 is displayed on a display device, for example.

  FIG. 4 is a flowchart for explaining the creation of “business process definition” and “resource instance”. Next, with reference to FIG. 4, an operation from creation of “business process definition” and “resource instance” to be simulated to execution of simulation will be described.

(S401)
In step S <b> 401, the user uses the process definition input unit 312 to input a “business process” composed of a chain of a plurality of tasks. The process definition input unit 312 receives an input of “business process” by the user. FIG. 5A is a diagram for explaining the input of the business process. An example will be described with reference to FIG. The process definition input unit 312 receives an input of a “business process” composed of a chain of a plurality of tasks, task A to task E.

(S402)
In S <b> 402, the user refers to the resource defined in the resource definition storage unit 313 using the process definition input unit 312, and inputs “resource setting information” for the tasks constituting the input business process. (S402). “Resource setting information” is information that specifies which task stored in the resource definition storage unit is set for which task of the business process, and sets the resource for that unit in units of task chain This is information including “chain resource setting” that specifies The “resource setting information” will be described with reference to FIG. In FIG. 5A, resource 1 is set for task A, resource 2 is set for task B, and resource 3 is set in this chain in units of task chains of task C and task D ("chain resource setting"). ), And resource 4 is set in task E. The process definition input unit 312 receives input of this “resource setting information” from the user. The process definition input unit 312 generates a “business process definition” including the “business process” input from the user in S401 and the “resource setting information” input from the user in S402, and the process definition storage unit 311 is output. FIG. 5A also shows a business process definition. 6 and 7 are examples of the notation of “business process definition”. In step S402, as described above, the resources necessary for executing each task are set in units of a chain of one or more tasks that require the same type of resource. That is, when a task chain requires the same resource, the resource can be set in the unit of task chain.

(Swimlane notation)
"Chain Resource Settings"
For example, as shown in FIG. 6, a plurality of tasks (task chain) may be specified using “swim lane notation” as shown in FIG. FIG. 6 shows a case where “operator, telephone” is set in the task chain of “question reception”, “survey”, and “answer”. For example, the process definition storage unit 311 displays an input screen of “swim lane notation” on the display device and accepts an input from the user.

(Outline task)
Alternatively, as shown in FIG. 7, “chain resource setting” may be expressed as “general task” and may be associated with the original business process as necessary, as described below. That is, when receiving the input of “chain resource setting”, the process definition input unit 312 receives an input as a “general task” in which the task chain unit is regarded as one task. Then, the process definition input unit 312 generates a “general business process” by replacing the chain of tasks corresponding to the “general task” with the general task among the business processes that have received the input in S401. And a business process definition including resource setting information. For example, as illustrated in FIG. 5B, the process definition input unit 312 receives a “chain resource setting” “set resource 3 for task C and task D” from the input screen of the display device. An input is accepted as “schematic task X” in which the chain unit of task C and task D is regarded as one task. Then, the process definition input unit 312 replaces the chain of tasks C and D corresponding to the “summary task X” with the summary task X among the business processes that have received the input in S401, thereby changing the “schematic business process”. Generate. FIG. 5B shows a “schematic business process”. The process definition input unit 312 generates a business process definition including “rough business process” and resource setting information, that is, information shown in FIG. 5B as a whole, and outputs the generated information to the process definition storage unit 311. FIG. 7 shows a case where the task chain of “question reception”, “survey”, and “answer” in FIG. 6 is changed to a general task “question answer”, and FIG. 7 is also a general business process. .

(Correspondence information)
In addition, the process definition input unit 312 generates correspondence information indicating the correspondence between the general task and the tasks constituting the general task, and outputs the correspondence relationship information to the process definition storage unit 311. The process definition storage unit 311 inputs and stores this correspondence information.

(Warning 1)
In S <b> 402, the process definition input unit 312 may detect “a chain of two or more tasks that require the same type of resource”, and present and warn the user. For example, in FIG. 5A, when the resource Y is set for the task A and the resource Y is also set for the task B, the process definition input unit 312 issues a warning. In this case, the resource Y can be set with the task A and the task B as a chain unit. For example, this can be notified to the user on the input screen.

(Warning 2)
In S402, the process definition input unit 312 may detect a task that requires two or more resources, display it on the input screen of the display device, and present and warn the user. For example, in FIG. 5C, the process definition input unit 312 issues a warning on the input screen when two resources of resource 4 and resource 5 are set for one task E. This warning allows the user to review the resource settings.

(About resource definition)
The “resource definition” referred to in the resource setting information input step of S402 and the resource instance generation step of S404 described later defines the resource type and the attribute type of each resource type. For example, if there are an operator and a telephone as the “resource type”, the “operator” has “attributes” such as name, skill level, and total work time.

(S403)
In step S <b> 403, the process definition input unit 312 outputs the “business process definition” generated from the “business process” and “resource setting information” input by the user, and stores them in the process definition storage unit 311.

(S404)
In S <b> 404, the user generates an instance of the resource defined in the resource definition storage unit 313 using the resource instance input unit 315. In the resource instance generation step of S404, a “resource instance” that can be used for simulation by the simulation execution unit 316 is set. The user uses the resource instance input unit 315 to generate a resource instance related to the resource specified by the resource setting information (S402). For example, if you want to perform a simulation assuming that three "operators" (resources) and three phones (resources) are available, create three operator instances and three phone instances. Set attributes. For example, in the case of an operator, a name “Mr. Aoki”, a skill level “B”, a total work time “0”, and the like are set as attribute values. The values of these attributes are updated when the simulation is executed. For example, the time required for task execution is added to the total work time, or the skill level increases when the total work time exceeds a certain value.

(Automatic resource instance generation)
When generating a resource instance, the user may specify only the type and number of resource instances in the resource instance input unit 315, and the resource instance input unit 315 may automatically generate attribute values. The value of the attribute to be generated may be the same value, or may be a random number generated by specifying a probability distribution. As described above, when the resource instance input unit 315 receives the input of the type and the number of resources, the resource instance input unit 315 generates the number of resource instances having the predetermined default value that are the resource instances of the type that have received the input. To the resource instance storage unit 314.

(S405: Instance storage)
In step S <b> 405, the resource instance input unit 315 outputs “resource instance” to the resource instance storage unit 314 and stores it.

(S406: Execution of simulation)
In S406, the simulation execution unit 316 executes a business process simulation in the “business process definition” using the “business process definition”, “resource definition”, and “resource instance”.

  Although the business process simulator 310 as an apparatus has been described in the first embodiment, the operation of the business process simulator 310 is considered by processing the operation of each component such as the process definition input unit 312 of the business process simulator 310 as a process. It can also be understood as a business process simulation program to be executed by a computer.

  Since the business process simulator 310 according to the first embodiment includes the process definition input unit 312, it is possible to set necessary resources in units of task chains that require the same type of resource. This makes it possible to simulate a situation where one worker (resource) performs a continuous related work. Therefore, a realistic simulation can be performed.

  The business process simulator 310 according to the first embodiment includes a process definition input unit 312 that can be input using swimlane notation. For this reason, when specifying a plurality of tasks using swimlane notation, resources can be set with detailed granularity. Therefore, there is an effect that a detailed simulation can be performed.

  In the business process simulator 310 according to the first embodiment, the process definition input unit 312 can input a chain of tasks as a “schematic business process”. For this reason, when expressed as “schematic business process”, it is possible to set the coarsest granularity within a range where the resource setting for simulation can be performed. Therefore, there is an effect that model creation and resource setting become easy.

  In the business process simulator 310 according to the first embodiment, the process definition input unit 312 generates correspondence information about the general task, so that the “general business process” can be associated with the original business process as necessary. . As a result, resource setting can be simplified and a detailed simulation can be performed.

  In the business process simulator 310 of the first embodiment, the process definition input unit 312 detects a user by detecting a chain of two or more tasks that require the same type of resource or a task that requires two or more resources. Present and warn. This has the effect of prompting the user to reconsider resource settings.

  In the business process simulator 310 of the first embodiment, the resource instance input unit 315 generates the specified number of instances of the same type of resource. Thereby, the effect of facilitating resource instance generation when there is no need to distinguish individual resource instances can be obtained.

Embodiment 2. FIG.
Next, Embodiment 2 will be described with reference to FIGS. In the first embodiment, resources defined in advance are stored in the resource definition storage unit 313. Then, the user created an instance by using this pre-defined resource, and a simulation was performed. On the other hand, Embodiment 2 shows a case where the user himself creates a new resource definition.

  FIG. 8 is a block diagram of the business process simulator 310 according to the second embodiment. The business process simulator 310 according to the second embodiment further includes a resource definition input unit 317 as compared with the business process simulator 310 according to the first embodiment. Other than that is the same as FIG.

  In FIG. 8, a resource definition input unit 317 provides a user with a function of inputting a resource definition. The resource definition input unit 317 stores “resource definition” input by the user in the resource definition storage unit 313.

Next, an operation in which a user inputs a resource definition will be described with reference to FIG.
(1) The user inputs a resource definition using the resource definition input unit 317 (S801).
(2) The resource definition input unit 317 stores the resource definition in the resource definition storage unit 313 (S802). The resource input from the resource definition input unit 317 can be used in the simulation (S406) in the same manner as the resource defined in advance.

  The operation in which the user creates “business process definition” and “resource instance” to be simulated and executes the simulation is the same as in FIG. The timing for performing the operation of defining and storing the resource in FIG. 9 is not limited to before performing FIG. 4, but may be any time after S401, S402, and S404, which are user operations in FIG.

(Resource definition notation)
As the notation of the resource definition, for example, an ER (Entity-Relationship) diagram or a UML (Unified Modeling Language) class diagram may be used.

(Example of resource definition)
10, FIG. 11, and FIG. 16 are examples of resource definitions represented by class diagrams. In FIG. 10, a resource called an operator having an attribute of a model in charge is defined.

  FIG. 11 is a business process definition expressed in swim lanes using the resources defined in FIG. The upper and lower swim lanes represent operators of which the attributes of the model in charge are “A model” and “B model”, respectively. The middle swimlane indicates that it can be performed regardless of whether it is in charge of the A model or B model by not specifying the model in charge.

  FIG. 12 shows the business process definition of FIG. 11 as a schematic business process.

(Example of resource definition: inheritance)
In FIG. 13, three types of resources are defined: a resource called an operator, and an operator in charge of A model and an operator in charge of B model who “inherit” it. That is, the resource definition input unit 317 receives the input of the “inheritance relationship” (hierarchical relationship) between resources, generates the inheritance relationship information for the resource in accordance with the received “inheritance relationship” (hierarchical relationship), and generates The inheritance relationship information is stored in the resource definition storage unit 313. FIG. 14 shows a business process definition expressed in swim lanes using the resources defined in FIG. The upper and lower swim lanes respectively represent the operator in charge of model A and the operator in charge of model B. The middle swimlane indicates that it can be performed regardless of whether it is in charge of the A model or B model by designating a parent class called an operator. FIG. 15 represents the business process definition of FIG. 14 as “schematic business process”.

(Create new resources)
In FIG. 16, three types of resources are defined: a resource such as an operator and a telephone, and a call operator that aggregates them. That is, the resource definition input unit 317 receives an input of a combination of a plurality of types of resources, for example, an operator and a telephone, and generates a new resource “call operator” indicated by the combination of “operator and telephone” that has received the input. Output to the resource definition storage unit 313. The resource definition storage unit 313 stores the new resource “call operator” output from the resource definition input unit 317. FIG. 17 shows a business process definition expressed in swim lanes using the resources defined in FIG. FIG. 18 shows the business process definition of FIG. 16 as a schematic business process. 17 and 18 correspond to FIGS. 6 and 7.

  As described above, by using the resource definition input unit 317, the user can define a resource specific to the business process to be simulated.

  An effect that a resource having a common role can be defined can be obtained by enabling the inheritance relationship to be defined between two resource types.

  By combining two or more resource types so that a new resource type can be defined, there is an effect that it is not necessary to assign multiple resources when setting a resource required for business process definition Can do.
