The supply chain model generation system is provided with: a resource information generating device including a resource information generating unit that generates resource information on each of a plurality of resources disposed at any one of a plurality of sites, and a position acquiring unit that acquires resource position information indicating a site-internal position of the resource from a positioning device that measures the position of the resource within the site; the local resource management device comprises a local resource storage unit for storing resource information and resource position information in association with date and time information indicating the date and time at which the resource information is generated by the resource information generation device, a 1 st update unit for updating the resource information and the resource position information based on the date and time information, and a flag storage unit for storing flag information indicating whether the resource information and the resource position information stored in the local resource storage unit are updated by the 1 st update unit; the multi-site resource management device comprises a multi-site resource storage unit for storing resource information and resource location information generated for each of a plurality of resources disposed in each of a plurality of sites, a determination unit for determining, based on flag information stored in a flag storage unit of the site resource management device corresponding to each of the plurality of sites, that the resource information and resource location information stored in the site resource storage unit are updated, an acquisition unit for acquiring, from the site resource storage unit included in the site resource management device corresponding to the site determined by the determination unit, the resource information and resource location information updated by the 1 st update unit, and a 2 nd update unit for updating the resource information stored in the multi-site resource storage unit using the resource information and the resource location information acquired by the acquisition unit; and a model generating device having a model generating unit that generates a supply chain model using the resource information and the resource position information stored in the multi-site resource storage unit updated by the 2 nd updating unit.

According to the present invention, a multi-site resource management device identifies a site where resource information and resource location information are updated based on flag information of a site resource management device corresponding to each of a plurality of sites, and acquires updated resource information and resource location information from a site resource storage unit corresponding to the identified site. The multi-site resource management device updates the resource information and the resource location information stored in the multi-site resource storage unit by using the acquired resource information and the resource location information. Then, the model generating device generates a supply chain model using the resource information and the resource position information stored in the multi-point resource storage unit. Thus, when the resource information and the resource location information stored in the local resource storage unit are updated, the resource information and the resource location information stored in the multi-local resource storage unit are updated in response to the update of the resource information and the resource location information stored in the local resource storage unit. Accordingly, the resource information and the resource position information stored in the multi-point resource storage unit are updated as the resource information and the resource position information related to the resource which is the component of the supply chain are changed, and therefore, there is an advantage that a supply chain model conforming to the actual state of the supply chain is generated.

Then, the global resource management device 2 acquires various resource information only from the point where the flag information is set to on. This can prevent the global resource management device 2 from wastefully acquiring various resource information from all the local DBs 331 and 2331 even if the contents of the local DBs 331 and 2331 are not updated. Thus, for example, there are the following advantages: even when the number of points increases, the processing load of the global resource management device 2 is suppressed from increasing.

Next, the resource information generation processing performed by each of the device information generation device 5, the worker information generation device 6, the provider information generation device 7, the transportation information generation device 8, and the transportation information generation device 2008 according to the present embodiment will be described with reference to fig. 19. The resource information generation process starts when the power supply is turned on to the device information generation device 5, the operator information generation device 6, the provider information generation device 7, the transportation information generation device 8, and the transportation information generation device 2008, for example.

First, the device information generating unit 511, the operator information generating unit 611, the provider information generating unit 711, the transportation information generating unit 811, or the transportation information generating unit 2811 determines whether new information is input from the production device 51, the terminal devices 61, 71, 2081, or the transportation control device 81 (step S101). When it is determined by the device information generating unit 511, the operator information generating unit 611, the provider information generating unit 711, the transportation information generating unit 811, or the transportation information generating unit 2811 that no new information is input (step S101: no), the process of step S105 described later is directly executed.

On the other hand, the device information generating unit 511, the operator information generating unit 611, the provider information generating unit 711, the transportation information generating unit 811, or the transportation information generating unit 2811 determines that new information is input (yes in step S101). In this case, the device information generating unit 511, the operator information generating unit 611, the provider information generating unit 711, the transportation information generating unit 811, or the transportation information generating unit 2811 generates various resource information using the input information, and updates various DBs using the generated various resource information (step S102).

Here, the device information generating unit 511 generates device identification information, input component and material identification information, processed product discharge identification information, information indicating a scheduled time before processing, information indicating a scheduled time after processing, information indicating a processing time, and recording date and time information, using various device parameter information input from the PLC51a of the production device 51. Then, the device information generating unit 511 updates the contents of the processing content DB531, the delivery cycle DB532, and the production cycle DB533, respectively, using the generated various information. The worker information generation unit 611 generates worker identification information, income component and material identification information, finished product identification information, information indicating a work preparation time, information indicating a cleaning time, information indicating a work time, and recording date and time information, using the information indicating the work record of the worker input from the terminal device 61. Then, the operator information generating unit 611 updates the contents of the job content DB631, the job preparation time DB632, and the job time DB633, respectively, using the generated various resource information. The supplier information generating unit 711 generates supplier identification information, purchase book identification information, delivery identification information, information indicating a preparation time before manufacturing, information indicating a manufacturing time, information indicating a post-manufacturing delivery time, information indicating a number of available supplies, and recording date-time information, using the information indicating that the parts or materials were purchased from the supplier, which is input from the terminal device 61. The supplier information generator 711 updates the contents of the component and material DB731, the delivery date DB732, and the supply capacity DB733, respectively, using the generated various resource information. The transportation information generating unit 811 generates transportation device identification information, pre-transportation object identification information, post-transportation object identification information, information indicating a pre-transportation schedule time, information indicating a transportation time, information indicating a post-transportation schedule time, and recording date-time information, using parameter information indicating various parameters set in the transportation device 84, which is input from the transportation control device 81. Then, the transportation information generating unit 811 updates the contents of each of the transportation DB831, the transportation time DB832, and the transportation DB833 using the generated various resource information. The conveyance information generating unit 2811 generates conveyance unit identification information, pre-conveyance object identification information, post-conveyance object identification information, information indicating a pre-conveyance schedule, information indicating a conveyance time, information indicating a post-conveyance schedule, information indicating a transportable amount, and date and time information using the information indicating the type of conveyance person and the record of the conveyance schedule input from the terminal device 2081. Then, the transportation information generating unit 2811 updates the contents of the transportation DB2831, the transportation time DB2832, and the transportation DB2833 using the generated various resource information.

Next, the position acquisition units 512, 612, 712, 812, 2812 acquire position information of the corresponding resources (step S103). Here, the position acquisition unit 512 acquires the position information of the production device 51 from the positioning device 52. The position acquisition unit 612 acquires position information of the operator from the positioning device 62. The location acquisition unit 712 acquires location information of the provider from a server owned by the provider. The position acquisition unit 812 acquires the position information of the transport device 84 from the positioning device 82. The position acquisition unit 2812 acquires position information of the conveying unit from a terminal device provided in the conveying unit.

Next, the transmitting units 513, 613, 713, 813, 2813 acquire various resource information from the updated various DBs, generate packets containing the acquired various resource information and location information, and transmit the packets to the local resource management devices 3, 2003 (step S104).

Here, the transmitting unit 513 acquires various pieces of information from the processing content DB531, the delivery cycle DB532, and the production cycle DB533, generates a packet including the acquired various pieces of information and the positional information of the production device 51, and transmits the packet to the local resource management device 3. The transmitter 613 acquires various resource information from the job content DB631, the job preparation time DB632, and the job time DB633, generates a packet including the acquired various resource information and the position information of the operator, and transmits the packet to the local resource management device 3. The transmitter 713 acquires various resource information from the component and material DB731, the delivery date DB732, and the supply capacity DB733, generates a packet including the acquired various resource information and the location information of the provider, and transmits the packet to the local resource management device 3. The transmitting unit 813 acquires various resource information from the shipment DB831, the transportation time DB832, and the transportation amount DB833, generates a packet including the acquired various resource information and the position information of the transportation device 84, and transmits the packet to the local resource management device 3. The transmitting unit 2813 acquires various resource information from the conveyance object DB2831, the conveyance time DB2832, and the conveyance amount DB2833, generates a packet including the acquired various resource information and the position information of the conveyance unit, and transmits the packet to the local resource management device 2003.

After that, the device information generating unit 511, the operator information generating unit 611, the provider information generating unit 711, the transportation information generating unit 811, or the transportation information generating unit 2811 determines whether or not there is an end instruction for instructing to end the resource information generating process (step S105). The end instruction is generated, for example, when an operation for stopping the device information generating device 5, the worker information generating device 6, the provider information generating device 7, the transportation information generating device 8, and the transportation information generating device 2008 is performed by the user. When it is determined by the device information generating unit 511, the operator information generating unit 611, the provider information generating unit 711, the transportation information generating unit 811, or the transportation information generating unit 2811 that there is no end instruction (no in step S105), the process of step S101 is executed again. On the other hand, when the device information generating unit 511, the operator information generating unit 611, the provider information generating unit 711, the transportation information generating unit 811, or the transportation information generating unit 2811 determines that there is an end instruction (yes in step S105), the resource information generating process ends.

Next, the local DB updating process executed by the local resource management device 3 or 2003 according to the present embodiment will be described with reference to fig. 20. The local DB update processing starts, for example, when the local resource management device 3 or 2003 is powered on.

First, the acquisition units 311 and 2311 determine whether or not various resource information is received from the device information generating device 5, the worker information generating device 6, the provider information generating device 7, the transportation information generating device 8, or the transportation information generating device 2008 (step S201). When the acquisition units 311 and 2311 determine that the various resource information is not received (no in step S201), the processing in step S207 described later is executed.

On the other hand, the acquisition units 311 and 2311 determine that various resource information is received (yes in step S201). In this case, the 1 st updating units 312 and 2312 update the contents of the local DBs 331 and 2331 using the various resource information acquired by the acquiring units 311 and 2311 (step S202). Here, the 1 st updating sections 312 and 2312 determine whether or not various resource information corresponding to the same resource identification information as the resource identification information among the newly acquired various resource information has been stored in the local DB331. Then, when various resource information is stored in which the resource identification information matches the newly acquired various resource information, the 1 st updating unit 312 compares the recording date and time information corresponding to the resource identification information of the two, and deletes the resource information having the earlier recording date and time indicated by the recording date and time information from the local DB331.

Next, the flag setting sections 313 and 2313 set the flag information stored in the flag DBs 332 and 2332 to on (step S203).

Next, the transmitting units 314 and 2314 determine whether or not the transmission request information is received from the global resource management device 2 (step S204). When the transmission units 314 and 2314 determine that the transmission request information has not been received (no in step S204), the processing in step S207 described later is executed.

On the other hand, when the transmission units 314 and 2314 determine that the transmission request information is received (yes in step S204), the transmission units transmit the updated various resource information stored in the local DB331 to the global resource management device 2 (step S205). Thereafter, the flag setting sections 313 and 2313 set the flag information stored in the flag DBs 332 and 2332 to off (step S206).

Next, the transmitting units 314 and 2314 determine whether or not flag request information for requesting transmission of the flag information is received from the global resource management device 2 (step S207). When the transmitting units 314 and 2314 determine that the flag request information has not been received (no in step S207), the process in step S209 described later is directly executed again. On the other hand, when the transmitting units 314 and 2314 determine that the flag request information is received (yes in step S207), the flag information is acquired from the flag DBs 332 and 2332 and transmitted to the global resource management device 2 (step S208).

Next, the acquisition units 311 and 2311 determine whether or not there is an end instruction to end the local DB updating process (step S209). The end instruction is generated, for example, when an operation for stopping the local resource management device 3, 2003 is performed by the user. When the acquisition units 311 and 2311 determine that there is no end instruction (no in step S209), the process of step S201 is executed again. On the other hand, when the acquisition units 311 and 2311 determine that there is an end instruction (yes in step S209), the local DB updating process ends.

Next, the global DB updating process executed by the global resource management device 2 according to the present embodiment will be described with reference to fig. 21. The global DB update process starts when the global resource management device 2 is powered on.

First, the determination unit 211 determines whether or not the flag checking period has come (step S301). Here, the flag checking time managed by the local resource management device 3, 2003 is synchronized within a predetermined delay time range from the flag checking time managed by the local resource management device 3, 2003. When the determination unit 211 determines that the flag checking time has not come (no in step S301), the process in step S310 described later is directly executed.

On the other hand, when it is determined that the flag checking time has come (yes in step S301), the determination unit 211 transmits flag request information requesting transmission of the flag information stored in the flag DB332, 2332 of each of the local resource management devices 3, 2003 (step S302). Next, when receiving the flag information from the local resource management device 3, 2003, the determination unit 211 causes the flag information to be stored in the local list DB232 (step S303). Next, the determination section 211 retrieves flag information set to on with respect to the flag information stored in the local list DB232 (step S304). Then, the determination unit 211 determines whether or not flag information set to on is included in the flag information stored in the local list DB232 (step S305). When the determination unit 211 determines that the flag information set to on is not set (no in step S305), the process in step S310 described later is directly executed.

On the other hand, when determining that the flag information set to on is present (yes in step S305), the determination unit 211 determines the data point A, B corresponding to the flag information set to on (step S306). Next, the acquisition unit 212 transmits transmission request information requesting transmission of various resource information stored in the local DB331, 2331 to the local resource management device 3, 2003 corresponding to the point A, B specified by the specification unit 211 (step S307). Next, when the acquisition unit 212 receives various resource information from the local resource management device 3, 2003 (step S308), the 2 nd updating unit 213 updates the content of the global DB231 using the received various resource information (step S309).

Then, the determination unit 211 determines whether or not there is an end instruction to end the global DB updating process (step S310). The end instruction is generated, for example, when an operation for stopping the global resource management device 2 is performed by the user. When the determination unit 211 determines that there is no end instruction (no in step S310), the process in step S301 is executed again. On the other hand, when the determination unit 211 determines that there is an end instruction (yes in step S310), the global DB updating process ends.

Next, the model generation process performed by the model generation device 1 of the present embodiment will be described with reference to fig. 22. The model generation process starts, for example, when the model generation device 1 is powered on.

First, the reception unit 111 determines whether or not model generation request information is received from the user interface 104 (step S401). When the reception unit 111 determines that the model generation request information is not received (no in step S401), the process in step S406 described later is directly executed.

On the other hand, when the receiving unit 111 receives the model generation request information (yes in step S401), the selecting unit 112 transmits transmission request information requesting transmission of the various resource information stored in the global DB231 to the global resource management device 2 (step S402), and acquires the various resource information stored in the global DB231 (step S403). The selection unit 112 temporarily stores the acquired various resource information in the main storage unit 102, for example.

Next, the selection unit 112 selects resources as candidates of a plurality of resources necessary for realizing the optimal supply chain based on the model generation request information and the acquired various resource information (step S404). The selection unit 112 causes the selection resource DB131 to store various resource information corresponding to the selected resource.

Next, the model generating unit 113 generates a supply chain model of the final product to be produced, which is the most suitable for the production of the required prediction amount, using the various resource information corresponding to the plurality of resources selected by the selecting unit 112 (step S405). Then, the model generating unit 113 causes the model DB132 to store information indicating the generated supply chain model.

Then, the reception unit 111 determines whether or not there is an end instruction for instructing to end the model generation process (step S406). The end instruction is generated, for example, when an operation for stopping the model generating apparatus 1 is performed by the user. When the reception unit 111 determines that there is no end instruction (no in step S406), the process in step S401 is executed again. On the other hand, when the reception unit 111 determines that there is an end instruction (yes in step S406), the model generation process ends.

As described above, in the supply chain model generation system according to the present embodiment, the multi-site resource management device identifies a site where resource information is updated based on the flag information of the site resource management device corresponding to each of the plurality of sites, and acquires updated resource information from the site resource storage unit corresponding to the identified site. The multi-site resource management device updates the resource information stored in the multi-site resource storage unit by using the acquired resource information. Then, the model generating device generates a supply chain model using the resource information and the resource location information stored in the multi-point resource storage unit. Thus, each time the resource information stored in the local resource storage unit is updated, the resource information stored in the multi-local resource storage unit is updated so as to follow the update. Accordingly, the resource information stored in the multi-point resource storage unit is updated as the resource information related to the resource that is the component of the supply chain changes, and therefore, there is an advantage in that a supply chain model that matches the actual state of the supply chain is generated.

In the local resource management devices 3 and 2003 according to the present embodiment, the 1 st updating units 312 and 2312 update the resource information stored in the local DBs 331 and 2331 based on the date and time information and the resource identification information of each of the plurality of resources. Specifically, regarding the 1 st updating section 312, when various resource information is newly acquired, the 1 st updating sections 312, 2312 determine whether various resource information corresponding to the same resource identification information as the resource identification information among the newly acquired various resource information has been stored in the local DBs 331, 2331. Then, when various resource information is stored in which the resource identification information matches the newly acquired various resource information, the 1 st updating units 312 and 2312 compare the record date and time information corresponding to the resource identification information of both, and delete the resource information having the earlier record date and time indicated by the record date and time information from the local DB 331. Accordingly, since only the latest various resource information is always stored in the local DBs 331 and 2331, the storage capacity requested by the local DBs 331 and 2331 can be reduced in accordance with the latest various resource information.

The embodiments of the present invention have been described above, but the present invention is not limited to the configurations of the foregoing embodiments. For example, the global resource management device 2 may update the global DB231 in accordance with the update request information received from the local resource management device 3 or 2003 to update the global DB231. That is, the local resource management device 3 or 2003 may send update request information to the global resource management device 2, thereby updating the contents of the global DB231. The update request information includes, for example, command information for updating the global DB231 and various resource information stored in the updated local DBs 331, 2331.

For example, as shown in fig. 23, the global resource management device 3002 of the present modification example includes a permitted point list DB3233, an extraction unit 3214, and a comparison unit 3215. In fig. 23, the same reference numerals as in fig. 14 are given to the same structures as in the embodiment. The supply chain model generation system according to the present modification example corresponds to the supply chain model generation system according to the embodiment shown in fig. 1, in which the global resource management device 2 is replaced with the global resource management device 3002 according to the present modification example. The permitted site list DB3233 is a permitted site list storage unit that stores permitted site list information, which is identification information of a local resource management device, for example, the local resource device 3, corresponding to a site, for example, a site a, for which updating of the contents of the global DB231 is permitted by transmitting update request information.

The extraction unit 3214 extracts command information included in the update request information received from the local resource management device 3 or 2003 and the point identification information of the local resource management device 3 or 2003 of the source. The extraction unit 3214 extracts various resource information included in the update request information. The comparing unit 3215 compares the permitted site list information including the site identification information of the local resource management device stored in the permitted site list DB3233, for example, the local resource management device 3, with the site identification information of the source of the update request information extracted from the update request information by the extracting unit 3214. Then, the comparing unit 3215 determines whether or not the point identification information of the transmission source extracted from the update request information is included in the permitted point list information.

Next, the global DB updating process executed by the global resource management device 3002 according to the present modification will be described with reference to fig. 24. In fig. 24, the same processing as the global DB updating processing in the embodiment is given the same reference numerals as in fig. 21. After performing the series of processing of steps S301 to S309, the acquisition section 212 determines whether update request information is received from the local resource management device 3, 2003 (step S3001). When the acquisition unit 212 determines that the update request information has not been received (no in step S3001), the processing in step S310 and subsequent steps is directly executed.

On the other hand, when the acquisition unit 212 determines that the update request information is received (yes in step S3001), the extraction unit 3214 extracts the point identification information from the update request information (step S3002). Next, the comparing unit 3215 compares the point identification information stored in the permitted point list DB3233 with the point identification information of the transmission source extracted from the update request information (step S3003). Next, the comparing unit 3215 determines whether or not the point identification information of the transmission source extracted from the update request information is included in the permitted point list information (step S3004). The comparison unit 3215 determines that the point identification information of the source of the update request information is not included in the permitted point list information (step S3004: no). In this case, the 2 nd updating unit 213 discards the received update request information (step S3005), and thereafter, executes the processing of step S310 and thereafter.

On the other hand, when the comparing unit 3215 determines that the point identification information of the source of the update request information is included in the permitted point list information (yes in step S3004), the extracting unit 3214 extracts the command information and the various resource information from the update request information (step S3006). Next, the 2 nd updating section 213 updates the contents of the global DB231 using various kinds of resource information in accordance with the command information included in the received update request information (step S3007). Next, the processing of step S310 and subsequent steps is performed.

According to the present configuration, for example, a user at a site other than the site where the global resource management device 3002 is disposed can update the content of the global DB231 using the local resource management device 2003. Thus, maintainability of the global DB231 can be improved.

The local resource management device 3 or 2003 according to the embodiment may have a function of selecting the received information according to the source of the information transmitted to the local resource management device 3 or 2003.

For example, as shown in fig. 25, the local resource management device 4003 of the present modification includes a transmission source list DB4333, an extracting unit 4315, and a comparing unit 4316. In fig. 25, the same reference numerals as those in fig. 12A are given to the same structures as those in the embodiment. The supply chain model generation system according to the present modification example corresponds to the supply chain model generation system according to the embodiment shown in fig. 1, in which the local resource management device 3 is replaced with the local resource management device 4003 according to the present modification example, for example. The source list DB4333 stores source list information, which is a list of identification information of sources of various information such as production apparatus information and operator information that can be used to generate various resource information. The transmission source is the device information generating device 5, the operator information generating device 6, the provider information generating device 7, or the transportation information generating device 8.

The extraction unit 4315 extracts identification information of a transmission source included in various information received from the device information generating device 5, the operator information generating device 6, the provider information generating device 7, or the transportation information generating device 8. The comparing unit 4316 compares the transmission source list information stored in the transmission source list DB4333 with the identification information of the transmission source extracted by the extracting unit 4315. Then, the comparing unit 4316 determines whether or not the extracted identification information of the transmission source is included in the transmission source list information.

Next, the local DB updating process executed by the local resource management device 4003 according to the present modification will be described with reference to fig. 26. In fig. 26, the same reference numerals as those in fig. 20 are given to the same processes as those in the local DB updating process according to the embodiment. First, when it is determined in step S201 that the acquisition unit 311 has received various resource information (yes in step S201), the extraction unit 4315 extracts identification information of the transmission source of the various resource information from the header of the packet including the various resource information (step S4001).

Next, the comparing section 4316 compares the employed transmission source list information stored in the employed transmission source list DB4333 with the identification information of the transmission source extracted by the extracting section 4315 (step S4002). Next, the comparing unit 4316 determines whether or not the extracted identification information of the transmission source is included in the transmission source list information (step S4003). The comparison unit 4316 determines that the identification information of the transmission source is not included in the transmission source list information (step S4003: no). In this case, the 1 st updating unit 312 discards the received various resource information (step S4004), and thereafter, executes the processing of step S207 and thereafter.

On the other hand, the comparison unit 4316 determines that the identification information of the transmission source is included in the transmission source list information (yes in step S4003). In this case, the 1 st updating section 312 updates the content of the local DB331 using the received various resource information (step S202). After that, the processing of step S203 and thereafter is performed.

According to this configuration, for example, updating of the contents of the local DB331 using various resource information received from the masquerading apparatus information generating apparatus 5, the operator information generating apparatus 6, the provider information generating apparatus 7, or the transportation information generating apparatus 8 is suppressed. Thus, the security performance of the local DB331 can be improved.

In the supply chain generation system according to the embodiment, for example, the model generation device 1 may calculate a theoretical value of a time required from when the final product is ordered to when the final product is supplied according to the supply chain model. The supply chain system may further include a required time calculation device that calculates an average required time, which is an average of actual result values of required time from when the final product is ordered until when the final product is supplied to the order source in accordance with the supply chain model, and a route stability index value, which is a ratio of the average required time to a theoretical value of the required time. The required time calculation device is disposed in, for example, the production management department of the site a together with the model generation device 1. The required time calculation device may be provided with a user interface. In this case, the required time calculation means may present the average required time and the route stability index value to the user in response to the operation of inquiring the required time from when the final product is ordered to when the final product is supplied according to 1 supply chain model, via the user interface, by the user belonging to the production management department of, for example, the site a.

For example, as shown in fig. 27, the model generating device 4001 according to the present modification includes a CPU101, a main storage unit 102, an auxiliary storage unit 103, a user interface 104, a network communication unit 106, and a bus 109 connecting these units. In fig. 27, the same reference numerals as in fig. 16 are given to the same structures as in the embodiment. The CPU101 reads out the program stored in the auxiliary storage unit 103 to the main storage unit 102 and executes the program, thereby functioning as the reception unit 111, the selection unit 112, the model generation unit 113, and the required time theoretical value calculation unit 4114. The auxiliary storage unit 103 includes a selection resource DB131, a model DB132, and a required time theoretical value DB4133 storing required time theoretical value information indicating a theoretical value of required time corresponding to each of the generated supply chain models. The required time theoretical value DB4133 stores required time theoretical value information corresponding to each supply chain model in association with model identification information for identifying the supply chain model.

The required time theoretical value calculation unit 4114 calculates a required time theoretical value corresponding to each supply chain model based on the various resource information on the resource selected by the selection unit 112 stored in the selection resource DB131 and the supply chain model stored in the model DB 132. The required time theoretical value calculation unit 4114 calculates, for each supply chain model, a required time theoretical value from the order of the final product to the supply of the final product to the order source in accordance with the supply chain model, based on the pre-operation time, the post-operation time, the operation time, and the number of processes, which correspond to the plurality of resources constituting the supply chain model. The required time theoretical value calculation unit 4114 associates the required time theoretical value information indicating the calculated required time theoretical value with the model identification information and stores the information in the required time theoretical value DB4113.

When receiving theoretical value request information requesting transmission of the theoretical value of the required time from the required time calculation device 4009, the required time theoretical value transmission unit 4115 determines the required time theoretical value information corresponding to the supply chain model indicated by the model identification information included in the theoretical value request information. Then, the required time theoretical value transmitting section 4115 transmits the determined required time theoretical value information to the required time calculating device 4009.

The required time calculation device 4009 includes, for example, a general-purpose personal computer, and includes, for example, as shown in fig. 28, a CPU4901, a main storage 4902, an auxiliary storage 4903, a user interface 4904, a network communication unit 4906, and a bus 4909 that connects these units. The auxiliary storage 4903 stores programs for realizing various functions of the required time calculation device 4009. The user interface 4904 is the same as the user interface 104 described in the embodiment. The network communication unit 4906 is connected to, for example, a network NT1 laid on the site a.

The CPU4901 reads out the program stored in the auxiliary storage 4903 to the main storage 4902 and executes it, thereby functioning as the actual result value acquisition unit 4911, the theoretical value acquisition unit 4912, the average required time calculation unit 4913, the stability index value calculation unit 4914, the inquiry reception unit 4915, and the required time presentation unit 4916 for acquiring the required time actual result value information indicating the required time actual result value corresponding to the required time of the supply chain model. The auxiliary storage 4903 includes an actual result DB4931 and a required time DB4932. For example, as shown in fig. 29A, the actual performance DB4931 stores, in association with actual performance identification information for identifying the actual performance of the supply of the corresponding final product, actual performance date and time information indicating the date and time at which the actual performance of the supply was generated, model identification information of the supply chain model to be used, and desired time theoretical value information indicating the desired time theoretical value corresponding to the supply chain model to be applied, the desired time actual performance value information indicating the actual time required from when the final product was ordered until the final product was supplied to the order source in accordance with the supply chain model. The required time DB4932 is stored by distinguishing, for each month of application of the supply chain model, average required time information indicating the average required time of the aforementioned actual required times from route stability index value information indicating the route stability of the flow route according to the supply chain model. For example, as shown in fig. 29B, the required time DB4932 stores average required time information and path stability index value information in association with application month information indicating the month of application of the supply chain model, application time period information indicating the time period of application of the supply chain model, and model identification information.

Returning to fig. 28, the actual performance value acquiring unit 4911 acquires, for example, actual performance value information indicating the actual performance value of the required time input by the user belonging to the production management department via the user interface 4904 or the actual performance value of the required time managed by the global resource management device 2. The required time actual performance value information includes model identification information for identifying a corresponding supply chain model. The actual result value obtaining unit 4911 stores the obtained required time actual result value information in the actual result DB4931.

The theoretical value acquisition unit 4912 transmits theoretical value request information requesting transmission of the required time theoretical value information to the model generation apparatus 4001, thereby acquiring the required time theoretical value information from the model generation apparatus 4001. Here, the theoretical value acquisition unit 4912 extracts the model identification information from the required time performance value information, generates theoretical value request information including the extracted model identification information, and transmits the theoretical value request information to the model generation apparatus 4001. The theoretical value acquisition unit 4912 associates the acquired required time theoretical value information with the required time actual result value information acquired by the actual result value acquisition unit 4911, and stores the information in the actual result DB4931.

The average required time calculation unit 4913 is a representative value calculation unit that calculates an average required time, which is an average value of the required time actual result values, from the required time actual result values as a representative value of the required time actual result values. The average required time calculation unit 4913 classifies the required time actual performance value information according to the combination of the month and the time zone to which the corresponding supply chain model is applied. Then, the average required time calculation unit 4913 calculates an average required time, which is an average value of the required time actual performance values indicated by the required time actual performance value information, for each combination of the month and the time zone in which the supply chain model is applied. Then, the average required time calculation unit 4913 associates the average required time information indicating the calculated average required time with the model identification information, month, and time, and stores the information in the required time DB4932.

The stability index value calculation unit 4914 calculates a path stability index value corresponding to a ratio of the average required time to the required time theoretical value for each combination of the month and the time zone in which the supply chain model is applied. The closer the path stability index value is to 100% of the average required time, the closer the required time theoretical value is to, indicating that the flow path according to the supply chain model is more stable. The stability index value calculation unit 4914 associates route stability index value information indicating the calculated route stability index value with model identification information, month, and time slot, and stores the information in the required time DB.

The inquiry reception unit 4915 determines whether or not the user interface 4904 receives the required time inquiry information for inquiring about the required time corresponding to the supply chain model. Here, the inquiry reception unit 4915 receives the required time inquiry information when the user performs an operation for inquiring about the required time via the user interface 4904. The required time inquiry information contains model identification information of a supply chain model related to an inquiry from a user and information indicating the month and time of application of the supply chain model.

The required time presentation unit 4916 determines whether or not there is average required time information corresponding to a combination of the model identification information included in the required time inquiry information and the month of application of the supply chain model, among the average required time information stored in the required time DB 4932. When it is determined that the average required time information is included in the average required time information stored in the required time DB4932, the required time presentation unit 4916 presents, via the user interface 4904, the average required time indicated by the average required time information and the route stability index value indicated by the route stability index value information corresponding thereto. When it is determined that the average required time information does not exist in the average required time information stored in the required time DB4932, the required time presenting unit 4916 presents the required time theoretical value indicated by the required time theoretical value information acquired from the model generating apparatus 4001 via the user interface 4904.

Next, a part of the operation of the supply chain model generation system according to the present modification will be described with reference to fig. 30. In fig. 30, the same reference numerals as those in fig. 18 are given to the same processes as those in the supply chain model generation system described in the embodiment. After executing the series of processes up to step S41, the model generating device 4001 calculates a required time theoretical value corresponding to the generated supply chain model, and stores the calculated theoretical value in the required time theoretical value DB4133 (step S4001).

Next, when the required time calculation device 4009 acquires the required time actual result value information (step S4002), it generates theoretical value request information for requesting transmission of the required time theoretical value information to the model generation device 4001 (step S4003). Next, the generated theoretical-value request information is transmitted from the required-time calculating device 4009 to the model generating device 4001 (step S4004). The theoretical value request information includes model identification information included in the required time actual result value information. On the other hand, the model generation device 4001 determines required time theoretical value information corresponding to the supply chain model to which the model identification information included in the theoretical value request information is added (step S4005). Next, the determined required time theoretical value information is transmitted from the model generating device 4001 to the required time calculating device 4009 (step S4006).

On the other hand, when the required time theoretical value information is received, the required time calculation device 4009 associates the received required time theoretical value information with the required time actual result value information and stores the information in the actual result DB4931 (step S4007).

Thereafter, the required time calculation device 4009 calculates an average required time corresponding to the application month and the application time period to which the actual result generation date and time of the acquired required time actual result value information belongs (step S4008). The required time calculation means 4009 causes the required time DB4932 to store average required time information indicating the calculated average required time. Next, the required time calculation means 4009 calculates a path stability index value corresponding to the ratio of the average required time to the required time theoretical value (step S4009). The required time calculation device 4009 associates the route stability index value information indicating the calculated route stability index value with the average required time information and the model identification information and stores the information in the required time DB4932.

In addition, it is assumed that, for example, a user belonging to the production management department performs an operation for inquiring about a required time via a user interface. In this case, the required time calculation unit 4009 receives the required time inquiry information (step S4010). Next, the required time calculation device 4009 searches the required time information stored in the required time DB4932, and determines that there is average required time information corresponding to a combination of the model identification information included in the required time inquiry information and the month of the application of the supply chain model (step S4011). In this case, the required time calculation device 4009 acquires the average required time information and the path stability index value information from the required time DB4932, and presents the acquired average required time indicated by the average required time information and the path stability index value indicated by the path stability index value information via the user interface 4904 (step S4012).

Next, with reference to fig. 31, a model generation process performed by the model generation device 4001 of the present modification will be described. In fig. 31, the same reference numerals as those in fig. 22 are given to the same processes as those in the model generation process described in the embodiment.

First, after performing the series of processing from step S401 to step S405, the required time theoretical value calculation unit 4114 calculates a required time theoretical value corresponding to the supply chain model generated by the model generation unit 113, and stores the calculated required time theoretical value in the required time theoretical value DB4133 (step S4401). Next, the required time theoretical-value transmitting section 4115 determines whether or not the theoretical-value request information is received from the required-time calculating device 4009 (step S4402). When it is determined by the required time theoretical-value transmitting section 4115 that the theoretical-value request information has not been received (step S4402: no), the process of step S406 is executed. On the other hand, when it is determined that the theoretical value request information is received (yes in step S4402), the required time theoretical value transmitting unit 4115 determines the required time theoretical value information corresponding to the supply chain model indicated by the model identification information included in the theoretical value request information (step S4403). Next, the required time theoretical value transmitting unit 4115 transmits the determined required time theoretical value information to the required time calculating device 4009 (step S4404). After that, the process of step S406 is performed.

Next, the average required time and path stability index value calculation process performed by the required time calculation device 4009 according to this modification will be described with reference to fig. 32. The average required time and path stability index value calculation process starts when the power supply is turned on to the required time calculation device 4009, for example. First, the actual performance value acquisition unit 4911 determines whether or not the required time actual performance value information is acquired (step S4901). When the actual result value acquisition unit 4911 determines that the required time actual result value information has not been acquired (no in step S4901), the process of step S4907 described later is directly executed.

On the other hand, when the actual result value obtaining unit 4911 obtains the required time actual result value information (yes in step S4901), the obtained required time actual result value information is stored in the actual result DB4931 (step S4902). Next, the theoretical value acquisition unit 4912 extracts the model identification information from the required time performance value information, generates theoretical value request information including the extracted model identification information, and transmits the theoretical value request information to the model generation apparatus 4001 (step S4903). Next, the theoretical value acquisition unit 4912 acquires the required time theoretical value information from the model generation device 4001, and stores the acquired required time theoretical value information in the required time DB4932 (step S4904).

Thereafter, the average required time calculation unit 4913 classifies the acquired required time actual performance value information according to the combination of the month and the time zone to which the corresponding supply chain model is applied (step S4905). Next, the average required time calculation unit 4913 calculates an average required time, which is an average of the required time actual performance values indicated by the required time actual performance value information, for each combination of the month and the time zone to which the supply chain model is applied, and associates the average required time information indicating the calculated average required time with the model identification information and the month and the time zone and stores the information in the required time DB (step S4906). Next, the stability index value calculation unit 4914 calculates a path stability index value corresponding to the ratio of the average required time to the required time theoretical value for each combination of the month and the time zone to which the supply chain model is applied, and stores path stability index value information indicating the calculated path stability index value in the required time DB4932 (step S4907).

Then, the actual performance value acquisition unit 4911 determines whether or not there is an end instruction for instructing to end the average required time and the route stability index value calculation process (step S4908). The end instruction is generated, for example, when an operation for stopping the required time calculation device 4009 is performed by the user. When the actual result value acquiring unit 4911 determines that there is no end instruction (no in step S4908), the process in step S4901 is executed again. On the other hand, when the actual result value acquiring unit 4911 determines that there is an end instruction (yes in step S4908), the average required time and route stability index value calculation process ends.

Next, the required time presentation process executed by the required time calculating device 4009 according to the present embodiment will be described with reference to fig. 33. The required time presentation process starts, for example, when the power supply is turned on to the required time calculation device 4009.

First, the inquiry reception unit 4915 determines whether or not the user interface 4904 receives the required time inquiry information for inquiring about the required time corresponding to the supply chain model (step S4951). Here, the inquiry reception unit 4915 receives the required time inquiry information when the user performs an operation for inquiring about the required time via the user interface 4904. When the inquiry reception unit 4915 determines that the required time inquiry information has not been received (step S4951: no), the process of step S4951 is repeated.

On the other hand, the inquiry reception unit 4915 receives the required time inquiry information (yes in step S4951). In this case, the required time presentation unit 4916 searches the required time information stored in the required time DB4932, and determines whether or not there is average required time information corresponding to a combination of the model identification information included in the required time inquiry information and the information indicating the month of application of the supply chain model (step S4952).

The required time presentation unit 4916 determines that there is average required time information corresponding to a combination of the model identification information and information indicating the month of the application and the time slot among the required time information stored in the required time DB4932 (yes in step S4952). In this case, the required time presentation unit 4916 acquires the average required time information and the route stability index value information from the required time DB4932, and presents the route stability index value indicated by the average required time and the route stability index value information indicated by the acquired average required time information via the user interface 4904 (step S4953).

On the other hand, the required time presentation unit 4916 determines that there is no average required time information corresponding to a combination of the model identification information and the information indicating the month of the application and the time slot among the required time information stored in the required time DB4932 (step S4952: no). In this case, the theoretical value acquisition unit 4912 extracts the model identification information from the required time inquiry information, generates theoretical value request information including the extracted model identification information, and transmits the theoretical value request information to the model generation apparatus 4001 (step S4954). Next, the theoretical value acquisition unit 4912 acquires the required time theoretical value information from the model generating device 4001 (step S4955). Next, the required time presentation unit 4916 presents the required time theoretical value indicated by the required time theoretical value information acquired by the theoretical value acquisition unit 4912 via the user interface 4904 (step S4956).

According to this configuration, the time required from the ordering of the final product to the supply of the final product to the ordering source according to the supply chain model can be presented to the user, and therefore, there is an advantage in that the user can easily grasp the timing of receiving the supply of the final product. Further, according to the present configuration, since the index value of the stability of the flow path according to the supply chain model can be presented to the user, there is an advantage in that the user can select the supply chain model to be applied in consideration of the stability of the flow path according to the supply chain model.

In the present modification, an example of the supply chain model generation system including the average required time calculation unit 4913 is described, wherein the average required time, which is the average value of the calculated required time actual performance values of the average required time calculation unit 4913, is used as the representative value of the required time actual performance values. However, the supply chain model generation system is not limited to this, and may include, for example, a representative value calculation unit that calculates a maximum value, an intermediate value, or a minimum value of the required time actual result value as a representative value of the required time actual result value.

In the embodiment, the examples in which the networks NT1 and NT2 are LANs suitable for the ethernet (registered trademark) standard have been described, but the present invention is not limited thereto, and may be, for example, a power line communication network. Alternatively, the device information generating device 5, the operator information generating device 6, the provider information generating device 7, the transportation information generating device 8, the transportation information generating device 2008, the local resource managing devices 3 and 2003, the global resource managing device 2, and the model generating device 1 are provided with wireless modules. In this case, the networks NT1 and NT2 may be wireless communication networks via access points. In this case, the device information generating device 5, the worker information generating device 6, the provider information generating device 7, the transportation information generating device 8, the transportation information generating device 2008, the local resource managing devices 3 and 2003, the global resource managing device 2, and the model generating device 1 may communicate with the access point by a communication system suitable for the short-range wireless communication standard, such as Bluetooth (registered trademark), for example. The device information generating device 5, the operator information generating device 6, the provider information generating device 7, the transportation information generating device 8, the transportation information generating device 2008, the local resource managing devices 3 and 2003, the global resource managing device 2, and the model generating device 1 are provided with infrared communication modules. In this case, the networks NT1 and NT2 may be networks that communicate via infrared rays that are suitable for the IR-DR standard.

In the embodiment, an example has been described in which the positioning devices 52, 62, 82 perform communication with the tags 53, 63, 83 to measure the position of the production device 51, the operator, or the transportation device 84. However, the positioning device 52 is not limited to this, and for example, may measure the position of the production device 51, the operator, or the transportation device 84 by using a GPS signal, or may measure the position of the production device 51, the operator, or the transportation device by using an electric wave suitable for a short-range wireless communication standard such as Bluetooth (registered trademark) transmitted from the production device 51, the operator, or the transportation device 84. Alternatively, the positioning devices 52, 62, 82 may use A-GPS signals or acoustic waves to determine the position of the production device 51, operator, or transport device 84.

Alternatively, in the embodiment, the positioning devices 52, 62, 82 and the tags 53, 63, 83 may not be present. In this case, for example, the device information generating device 5, the operator information generating device 6, and the transportation information generating device 8 may have user interfaces, and the user may directly input the position information of the production device 51, the operator, and the transportation device 84 to the device information generating device 5, the operator information generating device 6, and the transportation information generating device 8 via the user interface devices.

In the embodiment, an example in which the receiving unit 111 receives model generation request information including information indicating a required predicted amount of a target final product is described. However, the present invention is not limited to this, and for example, when the reception unit 111 receives identification information of a target final product, the sales performance information may be acquired from a server (not shown) that manages the sales performance information of the final product, and the future sales volume may be predicted based on the acquired sales performance information. Here, the reception unit 111 may predict the future sales of the target final product by using a known prediction method such as a linear regression method, an exponential smoothing method, a weighted moving average method, or a Holtz Winter method.

For example, a program for executing the above-described operations may be stored in a non-transitory recording medium (such as a CD-ROM (Compact Disc Read Only Memory) or a compact disc read only memory) readable by a computer system, and distributed to a computer connected to a network, and the program may be installed on the computer system to constitute the device information generating device 5, the worker information generating device 6, the provider information generating device 7, the transportation information generating device 8, the transportation information generating device 2008, the local resource management devices 3 and 2003, the global resource management device 2, and the model generating device 1, which execute the above-described processes.

In addition, a method of providing a program to a computer is arbitrary. For example, the program may be uploaded to a bulletin board (BBS (Bulletin Board System)) of a communication line, and transmitted to a computer via the communication line. Then, the computer starts up the program, and executes the same as other application programs under the control of an OS (Operating System). Thus, the computer functions as the device information generating device 5, the operator information generating device 6, the provider information generating device 7, the transportation information generating device 8, the transportation information generating device 2008, the local resource managing devices 3 and 2003, the global resource managing device 2, and the model generating device 1, which execute the above-described processing.
