FIG. 1 is a diagram illustrating an example of functional blocks of the production plan support system 1. The production plan support system 1 includes a production plan support device 100 and a plurality of company terminals 300. The production plan support apparatus 100 and each company terminal 300 are communicably connected via the network 200.

The production plan support device 100 is an information processing device such as a PC (Personal Computer) or a server computer, and is a device used by a business operator who provides a production plan support service using the production plan support system 1. The production plan support apparatus 100 includes a storage unit 110, a calculation unit 120, an input unit 130, an output unit 140, and a communication unit 150.

The storage unit 110 stores information necessary for supporting production plan execution. The arithmetic unit 120 controls the entire production plan support apparatus 100 in an integrated manner. The input unit 130 receives input of information to the production plan support apparatus 10 via an input device such as a keyboard or a touch panel. In addition to outputting a display screen to the output device, the output unit 140 transmits information such as an accommodation plan to be described later to the enterprise terminal 300 via the communication unit 150. Communication unit 150 transmits or receives information to / from company terminal 300.

The storage unit 110 stores resource information 111, company information 112, resource value information 113, shipping instruction information 114, and accommodation model information 115. The resource information 111 is information related to resources that support the execution of the production plan in the production plan support service. A resource means a resource necessary for producing and shipping a product. Resources include, for example, products, parts that are components of products, production equipment, production robots, transportation tools, tools such as jigs, production resources such as electricity and water, and human resources such as workers Is included.

The execution of the production plan includes the production plan and the ordering of resources according to the production plan.

The company information 112 is information about a company that uses the company terminal 300. The company information 112 is associated with a team company that can supply resources to the company without request for accommodation. Team companies are, for example, group companies that have a parent-child relationship in capital, or other companies that have concluded an agency contract. Team companies are treated as suppliers in line with the company.

The resource value information 113 is information that associates information that identifies a company that is a supplier that supplies the resource with an index that indicates the value of the resource for the company. A company that supplies resources refers to a company that handles resources. When the resource is a product, for example, the company that supplies the resource is a company that has equipment for producing the resource. Further, when the resource is a human resource, the company that supplies the resource is a company that has contracted with the worker who is the resource. A company that supplies resources is a company that supplies resources. It should be noted that a company included in the resource value information 113 does not necessarily mean that resources can be supplied when the resource value information 113 is referenced. The indicator will be described later.

The shipping instruction information 114 is one of the interchange models described later, and is information constituting a shipping instruction for a company. The shipping instruction information 114 is generated according to the situation in the later-described interchange model generation process.

The interchange model information 115 is information that associates an interchange model to be output for each company. Details will be described later.

The calculation unit 120 includes an accommodation candidate specifying unit 121, an accommodation model generation unit 122, an accommodation planning unit 123, and an ordering unit 124. When the accommodation candidate specifying unit 121 accepts the accommodation request from the company terminal 300, the accommodation candidate identification unit 121 identifies the amount of resources held by the team company, and if the amount held does not satisfy the accommodation request amount, one or more companies other than the team company are identified. Identify candidates for accommodation. The accommodation candidate specifying unit 121 specifies a company that is more easily accommodated as an accommodation candidate. Specifically, the accommodation candidate specifying unit 121 specifies the suppliers related to the resources related to the accommodation request in the resource value information as the accommodation candidates in descending order of value, details of which will be described later.

The accommodation model generation unit 122 generates an accommodation model corresponding to the accommodation candidate company and transmits it to the accommodation candidate company together with the supply request amount specified by the accommodation request amount. The accommodation model includes at least one of a shipping request model that controls conditions for shipping resources, and a management index maintenance constraint model that controls the management index in a candidate company of the accommodation to be equal to or greater than the value before accommodation.

The accommodation plan unit 123 creates an accommodation plan using the answer received from the candidate company that was the transmission destination of the accommodation model. The created accommodation plan is displayed on the output device by the output unit 140. Alternatively, the accommodation plan is transmitted by the output unit 140 to the company that transmitted the accommodation request.

When the ordering unit 124 receives information indicating the approval of the accommodation plan from the company that has requested the accommodation, the ordering unit 124 transmits ordering information including the resources and the supply amount to the candidate companies included in the accommodation plan. When the ordering unit 124 receives an input of information indicating approval of the accommodation plan via the input unit 130 when a predetermined condition is satisfied, the ordering unit 124 transmits the ordering information to the candidate company for accommodation. For example, when a business operator who uses the production planning support apparatus 100 exchanges a contract for directly placing an order with a company that is a request for accommodation in order to supply resources, the ordering unit 124 uses the input unit 130 to execute the accommodation plan. Approval can be accepted.

The company terminal 300 is an information processing apparatus such as a PC and is used by a resource supplier who subscribes to the production plan support service or a company who is a resource requester. It should be noted that a resource supplier in one situation is not prevented from being a resource requester in another situation.

The enterprise terminal 300 includes a calculation unit 310, an input unit 320, an output unit 330, and a communication unit 340. The arithmetic unit 310 controls the entire enterprise terminal 300 in an integrated manner. The input unit 320 receives input of information via an input device such as a keyboard or a touch panel. The output unit 330 displays a display screen such as an accommodation request input screen, which will be described later, on an output device (not shown) of the company terminal 300. The communication unit 340 transmits or receives information to and from the production plan support apparatus 100.

The calculation unit 310 includes an accommodation request unit 311 and a production planning unit 312. The accommodation request unit 311 generates information indicating an accommodation request using information specifying a resource and information indicating an accommodation request amount, which are input on an accommodation request input screen described later, and transmits the information to the production plan support apparatus 100. To do. The production planning unit 312 drafts a production plan including resources and suppliable quantities. The production planning unit 312 drafts a production plan using, for example, mathematical programming. Further, for example, the production planning unit 312 makes a production plan using dedicated software that the company terminal 300 has. In addition, for example, the production planning unit 312 realizes its function with dedicated software.

The network 200 is, for example, a public communication network such as a LAN (Local Area Network), the Internet, a WAN (Wide Area Network), or a communication network partially or entirely using a general public line such as a VPN (Virtual Private Network). It is.

In the present embodiment, a company that wants to receive resource accommodation inputs the resource to be accommodated and a supply request amount to the company terminal 300. When an accommodation request is received from one of the company terminals 300, the production planning support apparatus 100 determines whether or not resources can be provided from the team company of the company. When the resources provided by the team company are not sufficient, the production plan support apparatus 100 identifies another company as an accommodation candidate, generates an accommodation model suitable for the accommodation candidate company, and transmits it to the accommodation candidate company. .

The enterprise terminal 300 that has received the accommodation model calculates the supplyable amount using the accommodation model. The production plan support apparatus 100 creates the accommodation plan by identifying the resource accommodation source and the supply amount using the reply including the supplyable amount transmitted from the company terminal 300. Based on the created accommodation plan, an order is placed for the accommodation candidate.

This allows you to consult with other companies for flexibility when resources from your company or similar companies are not sufficient. Further, by generating and transmitting the above-described accommodation model, it is possible to supply resources to other companies that do not interfere with management indicators and shipping conditions even for other companies that carry out accommodation. Therefore, it is possible to more reliably procure resources based on the production plan.

FIG. 2 is a diagram illustrating an example of the data structure of the resource information 111. The resource information 111 includes a resource identifier, a type, and a set resource identifier. The resource identifier is identification information that identifies a resource that is a target of the production plan support service. The type is information indicating the type of resource. The type is information indicating a resource mode such as “item (product)”, “facility”, or “worker”.

The set resource identifier is identification information for specifying another resource when the resource is a set product with another resource. A set product is a product (resource) composed of a plurality of resources supplied simultaneously. For example, when the resource is a part, the set resource is information indicating a product generated using the part and other parts constituting the product. On the other hand, when the resource is a product composed of a plurality of parts, the set resource is information indicating each part as a component. Set resources are other resources that are associated with a resource and need to be shipped together.

FIG. 3 is information showing an example of the data structure of the company information 112. The company information 112 includes a company identifier and a team company identifier. The company identifier is identification information that identifies the company having the company terminal 300. The team company identifier is information for identifying a company having a relationship between the company and the team company.

FIG. 4 is information showing an example of the data structure of the resource value information 113. The resource value information 113 includes a resource identifier, a reference date, a company identifier, a location, a holding amount, and a value. The resource value information 113 is generated based on information received from each company terminal 300 before starting a production plan execution process described later.

The resource identifier is identification information that identifies a resource that is a target of the production plan support service. The reference date is information indicating a reference date for resource supply. The company identifier is information that identifies a company that supplies the resource. The location is information that identifies a resource supply base on a reference date for a resource supplier company. The holding amount is information for specifying the holding amount when the company holds resources on the reference date.

Value is a value that quantifies the merits of supplying resources to the company that supplies the resources. Value is an index per unit of resource. The value may be, for example, the value of the resource, but in reality, qualitative values such as social contribution are also emphasized. The method for calculating the value is not limited. For example, it is desirable for each company to calculate based on the latent value used in linear programming or a value equivalent thereto. In other words, the value can be said to be an index indicating the importance of the resource to the company that supplies the resource. In general, for the same resource, it can be considered that the lower the value, the more flexible it is.

In the resource value information 113 shown in FIG. 4, for the resource with the resource identifier “PROD2”, “X” is in the “company identifier” column, “8/23” is in the “reference date” column, and “retention amount” column is “100” is associated with “0” in the “value” column. This is because the company specified by “X” holds “100” units in “8/23” for the resource specified by “PROD2,” and the value of the resource is “0” for the company. It is shown that. When the value is “0”, it is considered that the resource is less important for the company “X”. Therefore, it can be considered that the resource is more likely to receive the resource interchange for the company requesting the accommodation than the other company with higher value.

FIG. 5 is a diagram showing an example of the data structure of the shipping instruction information 114. The shipping instruction information 114 includes a company identifier, a resource identifier, a location, a request accommodation time, an amount, and a price. The company identifier is information that identifies a company that is a resource request source. The resource is information that identifies the requested resource. The location is information indicating a base where the resource requester desires to supply the resource. The amount is information indicating the amount of the requested resource. The price is information for specifying the price of the resource desired by the resource requester.

FIG. 6 is a diagram illustrating an example of the data structure of the accommodation model information 115. The accommodation model information 115 includes a company identifier, a plan model type, an accommodation shipment request model, a KPI (Key Performance Indicator) maintenance constraint model, and a program.

The company identifier is information that identifies the company that supplies the resource. The plan model type is information for specifying a production plan model used when a company makes a production plan. For example, the plan model type is information indicating that production planning is performed by mathematical programming, or information that specifies software for performing production planning.

The interchange shipping request model is information that is a condition for shipping a resource. Specifically, the flexible shipping request model is information for adding a condition for shipping a resource in the production plan model specified by the plan model type. The KPI maintenance constraint model is information for adding a condition in the production plan model specified by the plan model type so that the management index in the enterprise is equal to or greater than the value before accommodation. It can be said that the KPI maintenance constraint model is a management index maintenance constraint model.

The program is information for identifying a program that generates a related flexible shipping request model and a KPI maintenance constraint model.

Next, a hardware configuration example of the production plan support apparatus 100 will be described.

FIG. 7 is a diagram illustrating a hardware configuration example of the production plan support apparatus 100. The production plan support apparatus 100 includes an input device 161, an output device 162, an external storage device 163, an arithmetic device 164, a main storage device 165, and a communication device 166, and each component is connected by a bus 167.

Note that the processing of each component of the production plan support apparatus 100 may be executed by one hardware or a plurality of hardware. The processing of each component of the production plan support apparatus 100 may be realized by one program or may be realized by a plurality of programs.

Also, the company terminal 300 has the same hardware configuration as that of the production plan support apparatus 100, and thus the description thereof is omitted.

FIG. 8 is a flowchart (part 1) showing an example of the production plan execution process. This process is performed in the production plan support apparatus 100. Before starting this processing, information is input to the interchange request input screen at the company terminal 300. The accommodation request unit 311 of the enterprise terminal 300 generates information indicating the accommodation request using the information input on the accommodation request input screen, and transmits the information to the production plan support apparatus 100. For example, when the production plan support apparatus 100 receives an accommodation request, it starts the processing of this flowchart.

FIG. 10 is a diagram illustrating an example of the accommodation request input screen 350. The accommodation request input screen 350 receives a resource input area 351 that accepts input of information for specifying resources, an input area 352 that accepts input when requesting accommodation is desired, and an input of the requested amount of accommodation. It includes an accommodation request amount input area 353, a desired price input area 354 for accepting input of a desired exchange price, a send button 355, and a cancel button 356. Note that the requested accommodation is time information such as date and time.

The accommodation request input screen 350 includes a place input area for receiving an input of a base serving as an accommodation destination, and a set number input area that is information for identifying a set product when the resource is a set product. Also good.

When the transmission button 355 is selected, the accommodation request unit 311 of the company terminal 300 receives information specifying the resource, request accommodation time, accommodation request amount, desired exchange price, and the like, which are input to the accommodation request input screen 350. The information indicating the accommodation request including the information for identifying the enterprise terminal 300 is generated and transmitted to the production planning support apparatus 100 including the information for identifying the company terminal 300.

Return the explanation to FIG. First, the accommodation candidate specifying unit 121 of the production plan support apparatus 100 specifies the accommodation request received from the company terminal 300 (step S1).

Next, the accommodation candidate specifying unit 121 specifies the input resource (step S2). Specifically, the accommodation candidate specifying unit 121 specifies a resource included in the accommodation request specified in step S1.

Next, the accommodation candidate specifying unit 121 determines whether or not the resource is a set product (step S3). Specifically, the accommodation candidate specifying unit 121 refers to the resource information 111 using the resource specified in step S2, and determines that the resource is a set product when there is a set resource related to the resource.

When the accommodation candidate specifying unit 121 determines that the resource is not a set product (“NO” in step S3), the accommodation candidate specifying unit 121 allocates the amount owned by the team company to the requested amount of accommodation (step S4). Specifically, the accommodation candidate specifying unit 121 refers to the company information 112 using information for specifying the company terminal 300 that has transmitted the accommodation request included in the accommodation request, and relates to the company having the company terminal 300. Extract team companies. The accommodation candidate specifying unit 121 refers to the resource value information 113 and extracts one or a plurality of records including a combination of the extracted team company and the resource specified in the accommodation request. The accommodation candidate specifying unit 121 extracts the holding amount by adding the holding amounts included in the extracted records.

Next, the accommodation candidate specifying unit 121 determines whether or not the supply request amount is 0 (step S5). Specifically, the accommodation candidate specifying unit 121 determines that the supply request amount is not 0 when the possessed amount extracted in step S4 is less than the accommodation request amount specified in the accommodation request.

More specifically, the accommodation candidate specifying unit 121 specifies the supply request amount by subtracting the holding amount extracted in step S4 from the accommodation request amount specified in the accommodation request. The accommodation candidate specifying unit 121 determines that the supply request amount is not 0 when the supply request amount is a positive value.

When the accommodation candidate specifying unit 121 determines that the supply request amount is 0 (in the case of “YES” in step S5), the resource relating to the accommodation request can be supplied within the team company, and to other companies Since there is no need to consult for accommodation, the calculation unit 120 of the production plan support apparatus 100 ends the processing of this flowchart. After that, the accommodation planning unit 123 may allocate resources of the requested amount of accommodation to each team company, and the ordering unit 124 may generate order information and transmit it to each team company.

When the accommodation candidate specifying unit 121 determines that the supply request amount is not 0 (in the case of “NO” in step S5), that is, when the supply request amount is a positive value, the accommodation candidate specifying unit 121 determines whether the supply request amount is Value information is acquired (step S6). Specifically, the accommodation candidate specifying unit 121 refers to the resource value information 113 using the resource specified by the accommodation request, and extracts one or a plurality of records including the resource.

Next, the accommodation candidate specifying unit 121 specifies a low-value company among companies that have not yet been specified (step S7). Specifically, the accommodation candidate specifying unit 121 extracts, from the records extracted in step S6, a record that includes a company that is not yet specified as an accommodation candidate and is not a company that has transmitted the accommodation request. The accommodation candidate specifying unit 121 specifies the record having the lowest value from the extracted records. The accommodation candidate specifying unit 121 specifies a company included in the specified record as an accommodation candidate.

Next, the accommodation model generation unit 122 generates and transmits an accommodation model (step S8). Specifically, the accommodation model generation unit 122 refers to the accommodation model information 115 using the company specified in step S7, and generates an accommodation model by executing a program related to the company.

An example of an accommodation model will be described. When the production plan model used when the enterprise that is the candidate for accommodation performs the production plan is the mathematical programming method, the accommodation model generation unit 122 includes information including, for example, the following constraint condition and objective function as the accommodation shipment request model: Is generated.

The quantity that can be shipped is defined as variable Z. Restriction: Z ≤ Supply requirement Quantity objective function (The solution to be maximized is the optimal solution): Price x Z

Also, the interchange model generation unit 122 generates information including the following constraint conditions, for example, as a KPI maintenance constraint model in mathematical programming.

The objective function value when the accommodation candidate does not make the accommodation is defined as the variable G1, and the objective function value when the accommodation candidate performs the accommodation is defined as the variable G2. Restriction condition: G2 ≧ G1

Next, when the production plan model used by a company that is a candidate for accommodation is dedicated software possessed by the company, the accommodation model generation unit 122 generates, for example, shipping instruction information 114 illustrated in FIG. 5 as an interchange shipping request model. . The accommodation model information 115 includes information for identifying the company that has transmitted the accommodation request, information for identifying the resource, location, request, and request included in the accommodation request by executing the program specified by the accommodation model information 115. The shipping instruction information 114 is generated by associating the accommodation time, the quantity, and the price.

Also, the interchange model generation unit 122 generates, for example, a setting file for the dedicated software as a KPI maintenance constraint model for the dedicated software. The production planning unit 312 of the enterprise terminal 300 calculates the supplyable amount when maintaining the KPI using dedicated software, but since a general method is used as the calculation method, detailed description thereof is omitted. For example, the KPI can be calculated using software having the technique disclosed in Japanese Patent Application Laid-Open No. 2007-213519. In this case, the accommodation model generation unit 122 generates a setting file that includes information for specifying resources, supply request amount, request accommodation time, and price. The setting file may include a constraint condition indicating that the KPI is maintained.

The accommodation model generation unit 122 generates an accommodation model including at least one of an accommodation shipment request model and a KPI maintenance constraint model by using a program associated with the candidate company in the accommodation model information 115, and the accommodation model is generated. Send to candidate. Note that the candidate company terminal 300 that has received the accommodation model is drafted by the production planning unit 312 to calculate the resource supply capability within a range that does not impair the management index.

Also, the accommodation model generation unit 122 transmits the screen information of the accommodation reply input screen to the accommodation candidate company terminal 300 together with the accommodation model.

FIG. 11 is a diagram showing an example of an accommodation reply input screen 360. The accommodation answer input screen 360 includes an accommodation request display area 361 and an accommodation answer input area 362. In the accommodation request display area 361, the requested company name, the set information, the information for identifying the resource, the location, the requested accommodation time, the accommodation request amount, and the desired exchange price are displayed.

For example, the accommodation model generation unit 122 of the production planning support apparatus 100 identifies the company that transmitted the accommodation request as the requested company name, using information included in the accommodation request. The accommodation model generation unit 122 identifies set information using information for identifying a set product when the resource identified by the accommodation request is a set product. The accommodation model generation unit 122 identifies the resource specified by the accommodation request, the base serving as the accommodation destination, the requested accommodation, the requested amount of accommodation, and the desired exchange price. The accommodation model generation unit 122 generates display information of the accommodation answer input screen 360 and transmits it to the company terminal 300 as a candidate for accommodation together with the accommodation model.

In the interchange response input area 362, an interchange company name, a suppliable amount, and a supply price are displayed so as to be inputable. When the production plan is drafted at the company terminal 300 and the available supply amount is determined, the input unit 320 accepts the input of the accepted company name, the available supply amount, and the supply price to the accommodation answer input area 362. Note that the production planning unit 312 may automatically acquire such information by executing the production planning model. The production planning unit 312 creates an answer including the information input in the interchange answer input area 362 and transmits it to the production planning support apparatus 100 via the communication unit 340.

Return the explanation to FIG. Next, the accommodation planning unit 123 updates the supply request amount (step S9). Specifically, the accommodation planning unit 123 assigns the supplyable amount included in the answer received from the accommodation candidate to the supply request amount. That is, the accommodation planning unit 123 specifies the supplyable amount as the supply amount when the supplyable amount is equal to or less than the supply request amount. When the supplyable amount exceeds the supply request amount, the accommodation planning unit 123 specifies the supply request amount as the supply amount. The accommodation planning unit 123 creates an accommodation plan by associating information for identifying a candidate company for which an answer has been transmitted, a supply amount, and a supply price.

Further, the accommodation planning unit 123 specifies a value obtained by subtracting the supply amount from the supply request amount as a new supply request amount.

In addition, in the enterprise terminal 300 that performs production planning using the production planning model of the mathematical programming method, when the above-mentioned interchange model is incorporated into the production planning model, the suppliable amount becomes a value equal to or less than the supply requirement amount.

Next, the accommodation planning unit 123 determines whether or not the supply request amount is 0 (step S10). Specifically, the accommodation planning unit 123 determines whether or not the new supply request amount specified in step S9 is zero.

If the accommodation planning unit 123 determines that the requested supply amount is not 0 (“NO” in step S10), the accommodation planning unit 123 moves the process to step S7 because there is a resource for which accommodation has not yet been determined. return. As a result, the processing from step S7 to step S10 is repeated until the total supply amount satisfies the accommodation requirement amount.

When the accommodation planning unit 123 determines that the requested supply amount is 0 (“YES” in step S10), the accommodation planning unit 123 determines the accommodation plan because the accommodation source of resources for the requested amount of accommodation has been determined. Confirm and output the result (step S11). Specifically, the accommodation planning unit 123 transmits the accommodation plan created in step S9 to the company terminal 300 that has transmitted the accommodation request. Note that the output unit 330 of the company terminal 300 displays an accommodation plan result screen indicating the accommodation plan, for example, based on an input operation via the input unit 320.

FIG. 12 is a diagram illustrating an example of the accommodation plan result screen 370. The accommodation plan result screen 370 has an accommodation request display area 371, an accommodation plan display area 372, and an approval button 373. In the accommodation request display area 371, information indicating the accommodation request is displayed. For example, in the accommodation request display area, the name of the requested company having the company terminal 300 that has transmitted the accommodation request, set information when the resource is a set product, information for identifying the resource, and a location serving as a supply base The requested accommodation time, the requested accommodation amount, and the desired exchange price are displayed.

In the accommodation plan display area 372, information indicating the accommodation plan is displayed. For example, in the accommodation plan display area 372, the name of the accommodation company, which is the company that is the accommodation source, the available supply amount, and the supply amount are displayed in association with the resource relating to the accommodation request. The accommodation planning unit 123 generates display information of the accommodation plan result screen 370 using the information included in the accommodation plan created in step S9, and transmits it to the company terminal 300 that has made the accommodation request.

Next, the accommodation plan unit 123 accepts approval of the accommodation plan (step S12). Specifically, when the approval button 373 on the accommodation plan result screen 370 displayed on the company terminal 300 is selected, the production planning unit 312 transmits information indicating approval to the production plan support apparatus 100. The accommodation planning unit 123 of the production plan support apparatus 100 receives information indicating that it has been approved.

Next, the ordering unit 124 transmits the ordering information to the flexible company (step S13). Specifically, the ordering unit 124 includes an order including information for specifying a resource for requesting accommodation and a supply amount with respect to the enterprise terminal 300 of one or a plurality of companies which are included in the accommodation plan and which is a resource accommodation source. Send information. Thereafter, the calculation unit 120 of the production plan support apparatus 100 ends the process of this flowchart.

If the company that transmitted the accommodation request wishes to place the order by itself, the company requesting the accommodation request may directly place the order from the company requesting the accommodation without going through the production planning support apparatus 100. Good.

If the predetermined condition is satisfied, the accommodation plan result screen 370 may be displayed on the output device 162 of the production plan support device 100 by the processing of the output unit 140. For example, in a region (not shown) of the storage unit 110, a flag indicating that a contract is concluded with a company that provides a production plan support service is associated with a company that has transmitted an accommodation request. In addition, the accommodation plan result screen 370 may be displayed on the production planning apparatus 100. In that case, when the input unit 130 accepts the selection of the approval button 373 on the accommodation plan result screen 370, the ordering unit 124 transmits the ordering information to each company of the accommodation source included in the accommodation plan.

In addition, when all companies included in the record extracted in step S6 are specified as accommodation candidates in step S7 described above, the supplyable amount of all companies that handle the resources requested for accommodation. Is considered to be less than the required capacity. Therefore, the accommodation planning unit 123 may display a screen indicating an error on the output device.

When the accommodation candidate specifying unit 121 determines that the resource is a set product (“YES” in step S3), the processing illustrated in FIG. 9 is performed.

FIG. 9 is a flowchart (part 2) illustrating an example of the production plan execution process.

Next, the accommodation candidate specifying unit 121 specifies one of the configuration resources that have not been specified yet (step S14). Specifically, the accommodation candidate specifying unit 121 extracts one or a plurality of set resources related in the resource information 111 with the resource specified in step S2, and again from the resources specified in step S2 and the extracted set resources. Identify one resource that has not been identified.

Since the processing performed from step S15 to step S21 is the same as the processing performed from step S4 to step S10, description thereof is omitted.

In step S16, the accommodation planning unit 123 determines that the supply request amount is 0 (in the case of “YES” in step S16), or in step S21, the accommodation planning unit 123 indicates that the supply request amount is 0. When it is determined that there is a resource (when “YES” in step S21), the accommodation candidate specifying unit 121 determines whether there is an unspecified configuration resource (step S24). Specifically, the accommodation candidate specifying unit 121 determines whether all of the resources specified in step S2 and the set resources extracted in step S14 have been specified in step S14.

When the accommodation candidate specifying unit 121 determines that there is an unspecified configuration resource (in the case of “YES” in step S24), the arithmetic unit 120 returns the process to step S14.

In step S21, when the accommodation planning unit 123 determines that the requested supply amount is not 0 (“NO” in step S21), the accommodation candidate specifying unit 121 determines whether all companies have been specified ( Step S22). Specifically, the accommodation candidate specifying unit 121 determines whether all of the companies included in the record extracted in step S18 have been specified.

When the accommodation candidate specifying unit 121 determines that all companies are not specified (in the case of “NO” in step S22), the calculation unit 120 returns the process to step S18. As a result, the processing from step S18 to step S21 is repeated for all companies that handle resources related to the accommodation request.

When the accommodation candidate specifying unit 121 determines that all companies have been specified (in the case of “YES” in step S22), the accommodation candidate specifying unit 121 outputs error information (step S23). Regarding the resources that make up a set product, even if all companies are specified, the supply requirement amount does not become zero. This means that the total supplyable amount of the resource does not satisfy the accommodation requirement amount, and the set product including the resource is not available. Indicates that is impossible. Accordingly, the accommodation candidate specifying unit 121 causes the output device 162 to display error information indicating that the accommodation of the set product is impossible in order to cancel the accommodation of the set product.

Note that the accommodation candidate specifying unit 121 may transmit error information indicating that the accommodation of the set product is impossible to the company terminal 300 that has transmitted the accommodation request.

When the accommodation candidate specifying unit 121 determines that there is no unspecified configuration resource (in the case of “NO” in step S24), the accommodation planning unit 123 performs the process of step 25. The processing performed from step S25 to step S27 is the same as the processing performed from step S11 to step S13, and thus description thereof is omitted.

According to the present embodiment, it is possible to efficiently request interchange with other companies that are not normally resource suppliers. In addition, the production plan support apparatus 100 used by a business operator that is neutral with respect to the resource supplier and the requester of the accommodation request performs the production plan execution process, so that each company is in a competitive state. Even so, it is possible to realize flexibility while keeping the status of each company secret. Even in other companies that can supply resources, it is possible to specify an amount that can be supplied in a range that does not impair management indicators. This contributes to improvement of productivity at the production site.

In addition, on the interchange request input screen 350 shown in FIG. 10, input of information indicating other companies that do not desire interchange may be accepted. When this information is received, in step S7 shown in FIG. 8 and step S18 shown in FIG. 9, the accommodation candidate specifying unit 121 performs an accommodation candidate specifying process so as to exclude the input company from the accommodation candidates. As a result, it is possible to execute a production plan that meets the needs of the company requesting the accommodation, such as excluding other companies with insufficient resource supply from the candidates for accommodation.

Further, in the present embodiment, the ordering unit 124 transmits ordering information to the company terminal 300 of the supply source using the created production plan. However, when the accommodation plan is approved, the ordering unit 124 may transmit forecast information including the resources and the supply amount included in the accommodation plan to the company terminal 300 that is the supply source. In that case, the ordering unit 124 transmits information indicating an order availability inquiry regarding the resource for which the forecast has been performed, for a predetermined period before request accommodation included in the accommodation plan. When the ordering unit 124 receives information indicating that ordering is possible, the ordering unit 124 transmits ordering information to each interchange candidate. As a result, for example, when it is a long time from when the request for accommodation is made until when the request is made available, the production plan can be efficiently executed by providing information to the accommodation source in advance.

If the resource is a part or product, the resource supply is completed by sending the resource from the supply source to the base of the supply destination. Information necessary for supply of resources is notified to a company that is a supply source or a supply destination as appropriate in accordance with, for example, an input to an input area (not shown) of an accommodation request input screen 350 or an accommodation response input screen 360.

For example, if the resource is a non-portable facility, the supply of the resource can be completed by operating the facility if the material and work procedure manual are sent to the supplier. Similarly, when the resource is a worker, the work procedure manual and the material may be transmitted to the supplier, and the worker performing the work may be handled as the resource supply completion. Even in such a case, for example, the resource type may be specified on the accommodation request input screen 350, and the work procedure manual may be attached on the accommodation plan result screen 370 to place an order with the supplier.
