Description

  The present invention relates to a supply chain management system that manages a procurement life cycle from a procurement plan to an execution plan change. The present invention relates to a supply chain management system particularly suitable for locally manufactured machined products and large-sized member assemblies.

  Large and single order products are assembled at the delivery site. In such a case, the parts procurement plan and the production plan are positioned equally. For example, a delay in parts procurement causes a delay in the production process. For this reason, it is necessary to prepare a parts procurement plan and create a plan table quickly and accurately. Further, when there is a change in the delivery date of parts, it is necessary to immediately change the parts procurement plan and production process.

  Usually, a supply chain structure is formed by a sales company, an assembly production company, a parts production company, or the like. In the supply chain system, a procurement plan that takes into account the production capacity and current production load of the assembly production company / parts production company is drawn up, and all of the affiliated companies can visually share it and respond flexibly to change events. Is required. As a result, the supply chain participating companies can improve the efficiency of production capacity allocation, and finally shorten the production period and improve the quality of the assembly.

  In the prior art, as disclosed in Japanese Patent Application Laid-Open No. 2002-207903, a purchaser, an assembly maker, and a parts maker use a wide area network such as the Internet to determine a production lead time. In addition, as disclosed in Japanese Patent Laid-Open No. 2003-15727, there is also a means for a product development / manufacturing company to centrally manage procurement plans for component makers and assembly makers. There are cases where companies that are the starting point of procurement, such as product development and manufacturing companies, use MRP (material requirements planning) systems.

  In the conventional technology, a management company such as a sales company centrally manages the procurement lead time. However, a sales company cannot always make a procurement plan that takes into account the current production situation and production load of an assembly production company and a parts production company.

  When a procurement plan that ignores the production capacity of an assembly production company or parts production company is drawn up, the assembly production company or parts production company can skip the inspection process and ship inferior products in time for procurement. There is also sex. In addition, after making a procurement plan, schedule changes such as delivery date changes may occur. Therefore, it is difficult to re-plan an optimal procurement change plan. Or it is assumed that change adjustment takes time.

  The object of the present invention is to shorten the period and improve the quality of production methods such as on-site assembly.

  According to the present invention, the supply chain management system includes a sales company, an assembly production company, a parts production company, and a procurement control agency.

  The sales company proposes a procurement configuration that matches the order information and provides assembly data and parts data. The assembly production company selects a parts production company based on the procurement configuration, assembly data, and part data, disassembles / distributes / combines parts data from the assembly data, inputs assembly data production lead time, and creates procurement plan data. The part production company inputs the part production lead time based on the part data. The procurement control agent company connects each company, transmits and directs procurement processing, and centrally manages procurement plans. In addition, each company manages and distributes programs used for procurement.

  The processing steps in the supply chain management system of the present invention include an initial basic procurement step starting from a sales company, a re-procurement step of changing a procurement plan after execution of the basic procurement step, an assembly replacement selection step, and a component replacement selection step.

  In the basic procurement process, an assembly procurement request is transmitted from the sales company to the assembly production company via the procurement control agency. The assembly production company selects a parts production company, inputs assembly production lead time, and creates procurement plan data. In addition, the part production company inputs the part production lead time. In addition, the procurement control agency registers the procurement plan. Sales companies and parts production companies can fetch procurement plan data from a procurement control agency.

  In the re-procurement process, a delivery date change notice is transmitted from the sales company to the assembly production company and the parts production company via the procurement control agency. The parts production company re-enters the parts production lead time. The assembly production company re-enters the assembly production lead time and re-creates the procurement plan. The procurement control agency updates the procurement plan registration. The sales company and the parts production company can capture the latest procurement plan data changed from the procurement control agency.

  In the assembly alternative selection process, a delivery date change notice is transmitted from the assembly production company to another assembly production company via the procurement control agency. The assembly company that received the delivery date change notification inputs assembly production lead time and creates a procurement plan. The procurement control agency determines the optimal procurement conditions, selects an alternative assembly production company, and updates the procurement plan registration. The sales company and the parts production company can capture the latest procurement plan data changed from the procurement control agency.

  In the part replacement selection process, a delivery date change notification is transmitted from the part manufacturing company to another part manufacturing company via the assembly manufacturing company. The assembly production company that has received the delivery date change notification inputs the part production lead time, determines the optimum procurement conditions, selects an alternative parts production company, and recreates the procurement plan. The procurement control agency updates the procurement plan registration. The sales company and the parts production company can capture the latest procurement plan data changed from the procurement control agency.

  According to the present invention, a sales company, an assembly production company, and a parts production company that form a supply chain structure share production plan data, parts data, and assembly data, so that each company takes into account the production situation. The time is calculated and the procurement plan is formulated and shared accurately based on the total. Furthermore, by distributing the procurement plan data, assembly data, and parts data to each company, the latest and optimum procurement plan data is created and automatically updated even if there is a schedule change such as a delivery date change. Share procurement plans among the companies that form the supply chain structure until the final implementation, and communicate the procurement plans at an early stage. As a result, it is possible to establish a production system in each company, to respond flexibly, and to improve the certainty of parts procurement.

  The sales company can adjust the delivery date according to the customer environment by the latest procurement plan. In addition, by consigning procurement planning control to a procurement control agency, planning and implementation adjustments can be omitted. The assembly production company can adjust the local assembly production system and speed up preparation. In the parts production company, the adjustment of the parts production system that matches the procurement plan and the relationship with other companies become clear. Furthermore, a re-procurement plan can be created in a short time by easily selecting an alternative assembly production company and an alternative part production company.

  Due to the above effects, in local production, it is possible to minimize the difference between the procurement plan for parts and the implementation of procurement in assembly production.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration diagram of the supply chain management system of this example. The supply chain management system in this example has a sales company 10, a procurement control agency 20, an assembly production company 30, and a parts production company 40. From the planning of procurement plans for parts, energy, human resources, etc. to manage. The sales company 10 inputs the procurement information of the ordered product, and the procurement information input terminal 11 for displaying the procurement plan data, the order management system 12 for managing the order information from the customer, and the product for managing the three-dimensional data of the product to be sold Data management system 13, procurement plan database 115 for storing procurement plan data, order information database 121 for storing order information from a customer as a starting point for procurement planning, and product database for storing three-dimensional data of products to be sold 131.

  The procurement control agency 20 includes a processing transmission server 21 that transmits procurement processing to each of the assembly manufacturing company 30 and the parts manufacturing company 40, a procurement management server 22 that centrally manages procurement plan data, and a transaction that stores information on business partners. It has a destination database 216 and a procurement plan database 224 that stores procurement plans.

  An assembly production company 30 inputs an assembly information input terminal 31 for inputting assembly information, disassembles assembly data and synthesizes part data, and generates a procurement / delivery server 32 for creating a procurement plan, and 3D data of assembly information of products to be sold. It has an assembly information database 324 for storing, a supplier database 325 for storing data relating to suppliers, a parts database 326 for storing three-dimensional data of parts of products to be sold, and a procurement plan database 327 for storing procurement plans. The parts manufacturing company 40 has a parts information input terminal 41 for embedding procurement lead time in part data, a procurement plan database 416 for storing a procurement plan, and a parts database 417 for storing three-dimensional data of parts. The terminals, systems, and servers of each company are connected to a network 3 based on the Internet.

  The assembly information input terminal 31 of the assembly manufacturing company 30 and the part information input terminal 41 of the part manufacturing company 40 have a viewing function, and visually display three-dimensional data such as assembly data and part data. be able to. Further, the assembly information input terminal 31 of the assembly production company 30 and the part information input terminal 41 of the part production company 40 download a dedicated program from the homepage of the procurement control agency before the execution of procurement.

  In the supply chain management system of this example, a route for transmitting delivery results from the customer site 1 via the mobile phone 2 is established. For example, access from the mobile phone 2 is connected from the mobile phone network to the processing transmission server 21 of the procurement control agency 20 via the Internet. Furthermore, a certificate authority 4 is installed to manage credit information between the companies. The certification authority 4 is operated with an authentication system 5 for managing credit information from each company. The certification authority may be installed in the procurement control agency 20.

  FIG. 2 shows a table in which processing for dynamically correcting a procurement plan is classified. The plan event 50 is classified into a pre-plan execution 56 and a plan execution 57. The pre-plan execution 56 indicates that the current procurement flow execution is immediately after the distribution of the procurement plan, and the plan execution 57 indicates that the current procurement flow execution is after the start of the procurement plan execution. Incidentally, the stage of carrying out the procurement plan is after the start of partial production at each assembly production company and parts production company. The delivery date change source 51 indicates a delivery date change request source company. The delivery date change request source is one of a sales company, an assembly production company, and a parts production company. The delivery date change event 52 is classified into an advance request 58 for shortening the delivery date in advance and a postponement request 59 for postponing the implementation time.

  The delivery date changeable condition 53 defines the correction possibility timing of the procurement plan data. The pre-assembly start 60 indicates a timing before the assembly production of the procured parts is started. Further, the pre-part production start 61 indicates a timing before the target part production company starts part production.

  The correspondence flow 54 shows a procurement flow corresponding to the plan event 50, the delivery date change source 51, the delivery date change event 52, and the delivery date changeable condition 53. The procurement flow includes a basic procurement chart 62 for starting a new procurement, a re-procurement chart 63 for executing the basic procurement chart again, an assembly alternative selection chart 64 for changing an assembly production company that meets the delivery date change request, and a delivery date. The parts are classified into a part replacement selection chart 65 for changing a part manufacturing company that matches the change request. In each column of the corresponding flow 54, one chart or two charts are defined. When two charts are defined, the upper part is a flow for newly creating a procurement plan, and the lower part is a change flow that matches the delivery date change. The corresponding flow condition 55 defines a constraint condition for executing the corresponding flow. For example, “target part production company before start of production 66” executes the procurement flow with the basic procurement chart first, and executes the re-procurement chart in response to the request to postpone the delivery date of the sales company. Indicates that the selected parts production company will be used as it is. If there is no delivery date change request before and during the plan execution, only the basic procurement chart is executed.

  The correspondence flow 54 of FIG. 2 includes four charts: a basic procurement chart 62, a re-procurement chart 63, an assembly replacement selection chart 64, and a part replacement selection chart 65. The procurement flow is composed of a combination of these four charts. Next, these four charts will be described in order with reference to the system function diagram of FIG. The processing path in FIG. 7 is indicated by a symbol such as (1).

  The basic procurement chart process will be described with reference to FIG. At the same time, refer to FIG. The assembly procurement request step in step S100 will be described. The user accesses the order management system 12 using the input / output device 111 of the procurement information input terminal 11 of the sales company 10. The order information search unit 122 of the order management system 12 extracts (1) order product procurement information from the order information database 121. The procurement information includes information necessary for procurement such as assembly data name, customer delivery date, and delivery conditions. The order information search unit 122 sends (2) the procurement information to the procurement event transmission unit 114 via the order information transfer unit 112 of the procurement information input terminal 11. The procurement event transmission unit 114 transfers (3) the assembly procurement request including the procurement information of the ordered product to the procurement event reception unit 211 of the processing transmission server 21 of the procurement control agency 20. In this way, the assembly procurement request is transmitted from the sales company 10 to the procurement control agency 20.

  Next, the assembly manufacturing company determination notification step in step S101 will be described. The procurement event reception unit 211 of the processing transmission server 21 of the procurement control agency 20 sends (4) an assembly procurement request to the procurement event analysis unit 214. The procurement event analysis unit 214 determines whether or not the assembly procurement request is a new request, and if it is a new request, writes it into the procurement configuration data storage unit 215 as new procurement information (5). The procurement event analysis unit 214 extracts the name of the assembly / production company currently executing the plan from the procurement configuration data storage unit 215, and then extracts the assembly other than the extracted assembly / production company currently executing the plan from the supplier database 216. The production company is extracted (6), and is written in the procurement configuration data storage unit 215 as company information. The procurement event analysis unit 214 extracts information on all parts production companies from the supplier database 216.

  The procurement event analysis unit 214 transfers (7) the procurement information to the procurement event transmission unit 212 via the procurement configuration data storage unit 215. On the other hand, the assembly / manufacturing company selection processing unit 213 selects (8) an assembly / manufacturing company from the company information written in the procurement configuration data storage unit 215 and transfers it to the procurement event transmission unit 212 (9). The procurement event transmission unit 212 transmits (10) the assembly production company decision notification, the procurement information, and the information of the parts production company to the procurement event reception unit 322 of the procurement collection and delivery server 32 of the selected assembly production company 30. In this way, the assembly production company determination notification is transmitted from the procurement control agency 20 to the assembly production company 30.

  Next, the assembly data fetching step of step S102 will be described. The procurement event reception unit 322 of the procurement collection and delivery server 32 of the assembly production company 30 requests (11) the assembly data transfer unit 321 to transfer assembly data. At the same time, the procurement event receiving unit 322 stores (12) the company information of the parts production company in the supplier database 325. The assembly data transfer unit 321 accesses the data input / output unit 132 of the product data management system 13 of the sales company 10 and requests transmission (13) of the assembly data. The data input / output unit 132 extracts assembly data from the product database 131 and transfers it to the assembly data transfer unit 321 of the assembly production company 30.

  Next, the part production company selection step in step S103 will be described. The assembly data transfer unit 321 of the procurement / delivery server 32 of the assembly production company 30 requests (14) the assembly data browsing unit 312 of the assembly information input terminal 31 to select a part production company. The assembly data browsing unit 312 takes in the information of the parts production company from the supplier database 325 (15) and stores it in the supplier data storage unit 314 (18). Similarly, assembly data is fetched from the assembly database 324 (16) and stored in the assembly data storage unit 313 (17). The assembly data browsing unit 312 expands the assembly data of the assembly data storage unit 313 into part data, and refers to the information of the part manufacturing company of the supplier data storage unit 314, and selects the part manufacturing company corresponding to the expanded part data. Select.

  The assembly data browsing unit 312 is equipped with a viewing function and can visually display three-dimensional data such as assembly data and component data. Further, it is assumed that the assembly data browsing unit 312 has downloaded a dedicated program from the homepage of the procurement control agent company before execution of the procurement, although not shown.

  Next, the component manufacturing company determination notification step in step S104 will be described. The assembly data browsing unit 312 of the assembly information input terminal 31 of the assembly production company 30 transfers (21) the company information about the selected parts production company to the procurement event transmission unit 323. The procurement event transmission unit 323 forwards (22) the company information regarding the selected parts production company to the procurement event reception unit 211 of the processing transmission server 21 of the procurement control agency 20. The procurement event analysis unit 214 updates the company information in the procurement configuration data storage unit 215 based on the company information related to the parts production company transmitted from the procurement event reception unit 211.

  Next, the parts procurement request step in step S105 will be described. The procurement event analysis unit 214 of the processing transmission server 21 of the procurement control agency 20 extracts the information of the parts production company from the procurement configuration data storage unit 215 and transfers (7) the information to the procurement event transmission unit 212. The procurement event transmitting unit 212 transfers (23) the component procurement request to the procurement event receiving unit 412 of the component information input terminal 41 of the component manufacturing company 40.

  Next, the component data fetching step of step S106 will be described. First, the assembly data browsing unit 312 of the assembly information input terminal 31 of the assembly production company 30 calls the component data decomposing unit 329 of the procurement and delivery server 32 (19), and instructs to decompose the assembly data into component data. The component data decomposing unit 329 stores the decomposed component data in the component database 326 (31). The procurement event reception unit 412 of the component information input terminal 41 of the component manufacturing company 40 calls the component data transfer unit 413 (24). The component data transfer unit 413 requests (25) the transfer of the component data from the component data transfer unit 331 of the procurement collection and delivery server 32 of the assembly production company 30. The component data transfer unit 331 transfers (26) the component data from the component database 326 to the component data transfer unit 413. The component data transfer unit 413 stores (27) the transferred component data in the component database 417.

  Next, the component production lead time input step of step S107 will be described. The part data transfer unit 413 of the part information input terminal 41 of the part manufacturing company 40 calls the part data browsing unit 414 (28). The component data browsing unit 414 reads the component data from the component database 417 (29), and displays the components three-dimensionally via the input / output device 411. The production lead time and delivery lead time of the parts are input via the input / output device 411. The lead time is input with reference to the specification description and delivery conditions embedded in the component data. An example of the lead time input process will be described later with reference to FIG.

  It is assumed that the parts data browsing unit 414 of the parts information input terminal 41 of the parts manufacturing company 40 has downloaded a dedicated program from the homepage of the procurement control agency before the execution of the procurement, although not shown. .

  Next, the component data sending step in step S108 will be described. The component data browsing unit 414 of the component information input terminal 41 of the component manufacturing company 40 calls the component data exchanging unit 413, reads the component data of the component database 417, and stores it in the component data of the procurement collection and delivery server 32 of the component manufacturing company 30. The data is transferred to the transfer unit 331 (28) (27) (25).

  The procurement / delivery server 32 constantly monitors the component data transferred via the component data transfer unit 331, and calls the component data composition unit 336 when all the component data is transferred (30).

  The component data composition unit 336 restores the assembly data from the component data while checking the production lead time and the delivery lead time, which are attribute data of the component data, and stores it in the assembly database 324.

  Next, the assembly production lead time input step of step S109 will be described. The assembly data browsing unit 312 of the assembly information input terminal 31 of the assembly production company 30 reads assembly data from the assembly database 324 and stores it again in the assembly data storage unit 313 (16) (17). The assembly data stored in the assembly data storage unit 313 is displayed via the input / output device 311. An assembly production lead time is input via the input / output device 311. The assembly production lead time is embedded in the assembly data as attribute data. An example of input processing of assembly production lead time will be described later with reference to FIG.

  Next, the procurement plan creation step in step S110 will be described. The assembly data browsing unit 312 of the assembly information input terminal 31 of the assembly production company 30 transfers the attribute data of the assembly data in the assembly data storage unit 313 to the plan data creation unit 332 (17) (32). The plan data creation unit 332 creates procurement plan data based on the attribute data of the assembly data, and stores it in the procurement plan database 327 (33). An example of procurement plan data is shown in FIG.

  Next, the procurement plan data sending step in step S111 will be described. The plan data transmission unit 328 of the procurement collection and delivery server 32 of the assembly production company 30 extracts the procurement plan data from the procurement plan database 327 and transfers it to the plan data receiving unit 221 of the procurement management server 22 of the procurement control agency 20. (35) (36).

  Next, the procurement plan registration step in step S112 will be described. Upon receiving the procurement plan data, the plan data receiving unit 221 of the procurement management server 22 of the procurement control agency 20 transfers the plan data to the plan data registration unit 222 (37). The plan data registration unit 222 registers (38) the procurement plan data in the procurement plan database 224 and reports (39) it to the plan data transmission unit 223.

  Finally, the procurement plan data capturing step of steps S113 and S114 will be described. The plan data transmission unit 223 of the procurement management server 22 of the procurement control agency 20 extracts (40) the procurement plan data from the procurement plan database 224, and the sales company and parts from the procurement configuration data storage unit 215 of the processing transmission server 21. The company information of the production company is obtained (41), and their addresses are extracted.

  The plan data transmission unit 223 of the procurement management server 22 first transfers (42) the procurement plan data to the plan data receiving unit 415 of the part information input terminal 41 of the part manufacturing company 40. The plan data receiving unit 415 stores (43) the procurement plan data in the procurement plan database 416.

  The plan data transmission unit 223 of the procurement management server 22 further transfers (44) the procurement plan data to the plan data reception unit 113 of the procurement information input terminal 11 of the sales company 10. The plan data receiving unit 113 stores (45) the procurement plan data in the procurement plan database 115.

  The parts production company 40 delivers the parts to the customer site 1 in FIG. 1 based on the procurement plan data. The mobile phone 2 transmits arrival information including the arrival date and time of the target part. The arrival information is transmitted to the procurement event reception unit 211 of the processing transmission server 21 of the procurement control agency 20 via the relay server and the network 3. The arrival information is written into the procurement configuration data storage unit 215 via the procurement event analysis unit 214. The arrival information is further transmitted to the procurement plan database 224 via the plan data transmission unit 223 of the procurement management server 22. Thereby, the target part schedule information of the procurement plan data in the procurement plan database 224 is updated.

  Next, the process of the re-procurement chart will be described with reference to FIG. At the same time, refer to FIG. First, the delivery date change notification step in step S150 will be described. The order management system 12 of the sales company 10 transfers (1) the delivery date change information to the order information transfer unit 112 of the procurement information input terminal 11. The order information transfer unit 112 refers to the corresponding order data in the procurement plan database 115 and requests the procurement event transmission unit 114 to transfer delivery date change information (2). The procurement event transmission unit 114 transfers (3) the delivery date change information to the procurement event reception unit 211 of the processing transmission server 21 of the procurement control agency 20.

  The re-lead time calculation request step in steps S151 and S152 will be described. When the procurement event reception unit 211 of the processing transmission server 21 of the procurement control agency 20 receives the delivery date change information, it transmits it to the procurement event analysis unit 214 (4). The procurement event analysis unit 214 accesses the procurement configuration data storage unit 215 and checks (5) whether the procurement plan has been executed. Here, it is assumed that the delivery date change is before the implementation of the procurement plan.

  The procurement event transmission unit 212 of the process transmission server 21 transfers (10) the delivery date change information to the procurement event reception unit 323 of the procurement collection / delivery server 32 of the assembly production company 30 and requests re-lead time calculation. At the same time, the procurement event transmission unit 212 of the processing transmission server 21 transfers (23) the delivery date change information to the procurement event reception unit 412 of the component information input terminal 41 of the component manufacturing company 40 and requests the re-lead time calculation.

  The procurement / delivery server 32 constantly monitors the component data transferred via the component data transfer unit 331, and calls the component data composition unit 336 when all the component data is transferred (30).

  Similar to step S108 described above, the part data composition unit 336 restores assembly data from the part data while checking the production lead time and the delivery lead time, which are attribute data of the part data, and stores them in the assembly database 324. .

  The component production lead time input step in step 153 and the component data transmission step in step 154 will be described. When the procurement event receiving unit 412 of the component information input terminal 41 of the component manufacturing company 40 receives the delivery date change information, it requests the component data browsing unit 414 to input the component manufacturing lead time. The component data browsing unit 414 embeds the component production lead time after changing the delivery date in the component data of the component database 417 (29). An example of inputting the component production lead time will be described with reference to FIG. Next, the component data transfer unit 413 of the component information input terminal 41 sends the component data to the component data transfer unit 331 of the procurement collection and delivery server 32 of the assembly production company 30 (25). The component data transfer unit 331 stores the component data in the component database 326 (26).

  The assembly lead time input step in step S155 and the procurement plan creation step in step S156 will be described. The assembly data browsing unit 312 of the assembly information input terminal 31 of the assembly production company 30 inputs the assembly production lead time again (46) (16) (17). An example of assembly production lead time input is shown in FIG. Next, the plan data creation unit 332 of the procurement collection and delivery server 32 of the assembly production company 30 again creates procurement plan data from the assembly data in the assembly database 324 (20) and stores it in the procurement plan database 327 (33). To do.

  The procurement plan data sending step in step S157 and the procurement plan registration step in step S158 will be described. The plan data transmission unit 328 of the procurement collection / delivery server 32 of the assembly production company 30 sends the changed procurement plan data stored in the procurement plan database 327 to the plan data receiving unit 221 of the procurement management server 22 of the procurement control agency 20. Send (36). The plan data registration unit 222 of the procurement management server 22 registers the transferred procurement plan data in the procurement plan database 224.

  The procurement plan data fetching step in steps S159 and S160 will be described. The plan data transmission unit 223 of the procurement management server 22 of the procurement control agency 20 includes a plan data reception unit 415 of the parts information input terminal 41 of the parts production company 40 and a plan data reception unit of the procurement information input terminal 11 of the sales company 10. The changed procurement plan data is transferred to 113 (37) (38) (39) (40) (41) (42) (44).

  Here, it was assumed that the delivery date was changed before the procurement plan was implemented. If the delivery date is changed during the implementation of the procurement plan, the part data information before the start of parts production is retrieved, and at the same time, the parts production company corresponding to this part data is notified, and after the part production lead time input in step S153 Perform the above steps.
