Description

Supply chain design system and supply chain design method

technical field

The present invention relates to techniques for designing supply chains for each case.

Background technique

In mass-customized products that realize one-product-style customized products with mass-production productivity, it is expected that the purchasing place/production place, etc. will be determined on a case-by-case basis based on the delivery place/delivery date/target original price/specification The independent supply chain design of the company makes it possible to adhere to the delivery date and bring high profits. However, the supply chain is determined in advance due to the difficulty in designing each case due to the huge combination of procurement locations/production locations. Therefore, it is impossible to follow changes in the business environment and changes in demand, resulting in a drop in the delivery date compliance rate/yield. In this regard, it is effective to derive a case-by-case supply chain design plan from a large portfolio in a short time for each case.

As a technique for deriving a supply chain design plan following changes in business environment and demand, there are conventional techniques such as the following Patent Documents 1 to 3.

Patent Document 1 describes a technique of "scheduling taking into account outsourced facilities when there is an order for which the delivery date is not secured" (refer to the specification abstract).

In Patent Document 2, a technique of "calculating the recommendation degree of a product for which the purchase unit price negotiation is preferentially performed" is described (refer to the abstract of the specification).

Patent Document 3 describes a technique that "setting information necessary for generating a common conveyance path can be easily set visually" (refer to the abstract).

SUMMARY OF THE INVENTION

The problem to be solved by the invention

The technology described in Patent Document 1 has a function of deriving a plan for studying outsourced processing when evaluation indicators such as delivery date and the like are not met in internal work. However, since the processing of the item is only outsourced to another company, it is necessary to separately decide where to manufacture or purchase the constituent items such as materials and components of the item. That is, the parts list (BOM: Bill Of Materials) does not change even if the processing of the item is entrusted to another company. In the manufacturing industry, in addition to outsourcing processing of the product, it may be purchased from other companies. When purchased by other companies, the materials and components of this type are also produced/purchased by other companies, so there is no need to conduct research on the supply chain of the materials and components of this type. In this case, the material and components of that variety are excluded from the BOM. In Patent Document 1, such a form is not considered as an object. Furthermore, since all combinations of internal work/external work switching studies are carried out, it is thought that it is difficult to derive in a short time.

In addition, the technology described in Patent Document 2 has a function of evaluating the room for negotiation of the purchase price of the item based on past order history information, but it is not possible to make a low price and short delivery by adjusting across a plurality of cases. The trading conditions for the purchase on the date.

In addition, in the technique described in Patent Document 3, a common conveyance path can be generated and an evaluation index value can be evaluated for the common conveyance condition input from the user, but the common conveyance condition itself cannot be automatically generated.

In this regard, an object of the present invention is to derive a case-by-case supply chain design plan from a large portfolio in a short period of time. In addition, for cases in which the evaluation index values such as delivery date and original price did not reach the target value in the case-independent design, production/purchasing/distribution conditions that can achieve the target value are generated.

Means for solving problems

In order to solve at least one of the above-mentioned problems, the supply chain design system of the present invention includes a calculation unit and a storage unit, wherein the storage unit stores at least one of the production base information and the purchasing place information, the case information and the item information, The case information includes the specifications of the delivered goods for each case received and the evaluation criteria of the supply chain design plan for each of the cases, the type information includes the types of the components constituting the delivered goods, and the production base information. The type and production conditions of the parts produced at the respective production bases are included, the procurement location information includes the types and procurement conditions of the parts procured from the respective procurement locations, and the computing unit generates, for each of the cases, the items including the components constituting the transaction. One or more supply chain design proposals at the production base or procurement place of each component of the goods, evaluate each of the supply chain design proposals based on the evaluation criteria, and generate changes for supply chain design proposals that do not meet the evaluation criteria An adjustment plan for the production conditions or the purchasing conditions is obtained so that the evaluation criterion is satisfied, and the generated adjustment plan is output.

Invention effect

According to one aspect of the present invention, it is possible to derive a case-by-case supply chain design that improves the delivery date compliance rate/yield.

Detailed ways

Hereinafter, although an Example is demonstrated, the scope of the present invention is not limited to an Example.

Hereinafter, embodiments of the present invention will be described based on the drawings. In the present embodiment, a case-by-case supply chain design of a target article is automatically generated. Examples of target items include lift devices such as elevators and escalators, electrical products, mechanical products, automobiles, trains, airplanes, generators, control devices, control panels, storage devices, and NAS (Network Attached Storage). storage) and other network storage, servers, water treatment devices, etc.

FIG. 1 is a diagram showing an example of functional modules of the supply chain independent design system 1 of the present embodiment.

The supply chain independent design system 1 includes a user terminal 2 , a database 3 , and a supply chain independent design device 10 that are communicably connected via each network CN.

The user terminal 2 is an information processing device such as a PC (Personal Computer), and is operated by a user of the supply chain design service provided by the supply chain independent design device 10 . The database 3 is, for example, a system that stores ERP (Enterprise Resource Planning) or the like, or a database or storage device that stores data according to the system.

The network CN connects the user terminal 2, the database 3, and the independent supply chain design device 10 in a communicable manner. The network CN is, for example, a LAN (Local Area Network, local area network), WAN (Wide Area Network, wide area network), VPN (Virtual Private Network, virtual private network), or the Internet, etc., which use ordinary public lines in part or all of the communication network. either.

The supply chain independent design device 10 is an information processing device such as a PC or a server computer. The supply chain independent design device 10 includes an input unit 11 , a calculation unit 12 , a storage unit 13 , an output unit 14 , and a communication unit 15 .

The input unit 11 accepts information input to the supply chain independent design device 10 via an input device such as a keyboard or a touch panel. The computing unit 12 derives a supply chain design plan for each case. The storage unit 13 stores information necessary for supply chain design. The output unit 14 causes an output device such as a display to output information. The communication unit 15 transmits and receives information with other devices connected via the network CN.

The input unit 11 includes a case information input unit 110 , an item information input unit 111 , a production base information input unit 112 , and a purchasing place information input unit 113 .

The case information input unit 110 , the item information input unit 111 , the production base information input unit 112 , and the purchasing place information input unit 113 acquire the required information from the user terminal 2 or the database 3 via the respective communication units 15 , and store the acquired information in the storage Section 13.

The calculation unit 12 includes a priority item order generation unit 120 , a supply chain design proposal generation unit 121 , a supply chain design proposal evaluation unit 122 , and an inter-issue adjustment unit 123 .

The priority item order generating unit 120 generates a priority item order for supply chain design. In supply chain design, as described above, items are not produced in internal operations (that is, production at the company's production base) but switched to external operations (that is, purchases based on purchases from other companies). In the case of breeds, there is no need to study the lower breeds. Therefore, studies are usually carried out from the highest cultivar of the BOM.

However, for example, due to the production or procurement status of the lower-level product, the delivery date may not be met, so internal work may be abandoned, and rework such as changing the production base of the upper-level product or re-examining external work may occur. In this regard, in order to prevent the occurrence of rework, it is desirable to generate a priority item order based on the load status of the production base and the transaction conditions of the purchasing place, and to study the supply chain design according to the priority item order. In order to reduce the rework when performing such a supply chain design, the priority item order generation unit 120 exists.

The priority item order generating unit 120 calculates each evaluation index for each item, generates a priority item order by integrating these evaluation indexes, and generates a priority item order for each case by comparing the integrated result of the case specification and the priority item order. The priority item order generating unit 120 stores the created priority item order information in the storage unit 13 .

The supply chain design proposal generation unit 121 generates a plurality of supply chain design proposals for determining the production base/production conditions and purchasing locations/purchasing conditions of each item in order of priority items for each item. The supply chain design proposal generation unit 121 stores the created supply chain design proposal information in the storage unit 13 .

The supply chain design proposal evaluation unit 122 calculates evaluation index values such as delivery date and original price with respect to the supply chain design proposal information created by the supply chain design proposal generation unit 121 . The supply chain design proposal evaluation unit 122 stores the created supply chain design proposal evaluation result information in the storage unit 13 .

The inter-case adjustment unit 123 confirms the evaluation results of the supply chain design plan for each case, extracts cases whose evaluation index values such as delivery date and original price do not reach the target value, and generates production/purchasing/distribution conditions that satisfy the target value of the evaluation index. In this case, the inter-case adjustment unit 123 not only generates production/purchasing/distribution conditions satisfying the target value of the evaluation index for each case, but also conducts a study that collects a plurality of cases.

For example, when there are a plurality of cases of purchasing the same item, price reduction is achieved by performing centralized purchasing such that the purchasing place is matched. In addition, when there are a plurality of delivery items to the same area at the same time period, the price reduction can be achieved by performing joint delivery such that the delivery date is matched. If there are multiple cases of in-house operations for the same product, price reduction can be achieved by performing concentrated production such as matching the production locations.

In this way, by performing adjustments such as centralized purchasing/co-distribution/centralized production across cases (that is, among multiple cases), the possibility of realizing a short delivery date/low price is explored, and a supply chain that satisfies the target value of the evaluation index is created. Design. The inter-case adjustment unit 123 stores the newly created supply chain design proposal information and supply chain design proposal evaluation result information in the storage unit 13 .

The storage unit 13 stores case information 130 , item information 131 , production base information 132 , purchasing place information 133 , priority item order information 134 , supply chain design proposal information 135 , and supply chain design proposal evaluation result information 136 .

The case information 130 is information related to the case that the company has received from the customer.

The item information 131 is BOM information necessary for manufacturing the target article.

The production base information 132 is information related to the production of the company.

The purchasing place information 133 is information (purchasing lead time, purchasing cost, etc.) related to purchasing between the supplier and the company. At the processing start time point, the purchasing place information 133 is set based on past transaction realities and agreements with suppliers.

The priority item order information 134 is the priority item sequence information for each item and the priority item sequence information for each case in each evaluation index for each item and the integrated result of each evaluation index.

The supply chain design information 135 is supply chain design information for each case. The supply chain design information consists of the production base/production condition, purchasing place/purchasing condition of each item constituting the specification, and identification information indicating whether the production condition/purchasing condition is different from the actual transaction and main value so far and needs to be negotiated again. In addition, for each case, a number of supply chain design proposals are stored.

The supply chain design plan evaluation result information 136 is result information for evaluating whether the supply chain design plan for each case has reached the target value of evaluation indicators such as delivery date and original price.

The output unit 14 includes a supply chain design proposal display unit 140 .

The supply chain design proposal display unit 140 acquires the supply chain design proposal and evaluation result information for each case stored in the case information 130 , the supply chain design proposal information 135 , and the supply chain design proposal evaluation result information 136 , and sends it to the user via the communication unit 15 Terminal 2. These pieces of information are displayed on the user terminal 2 . The evaluation result screen displays, for each case, the target value of the evaluation index values such as the production base/production condition, purchasing place/purchasing condition of each product, the target value of the evaluation index value, such as the current delivery date and original price, etc. and information indicating whether or not it has been reached.

In addition, in this embodiment, although the user terminal 2 and the database 3 are provided outside the supply chain independent design apparatus 10, the structure of the supply chain independent design system 1 is not limited to this. For example, the information stored in the storage unit 13 may be stored in the database 3 , and the computing unit 12 may acquire the information from the database 3 as necessary. The device configuration of the supply chain independent design system 1 can be appropriately changed as long as the purpose of the present embodiment is not impaired.

FIG. 2 is a diagram showing an example of the data structure of the matter information 130 of the present embodiment.

The case information 130 includes a case number 1301 , a delivery place 1302 , a delivery date 1303 , a target original price 1304 , a specification 1305 , and a quantity 1306 . Specification 1305 stores the name of the highest-level item in the BOM. In the present embodiment, the unit of the target original price 1304 is 10,000 yen for description.

FIG. 3 is a diagram showing an example of the data structure of the item information 131 of the present embodiment.

The variety information 131 includes a parent variety 1311 , a child variety 1312 , and a quantity 1313 . The item information 131 can also be referred to as general BOM information.

FIG. 4 is a diagram showing an example of the data structure of the production base information 132 of the present embodiment.

The production base information 132 includes: the factory 1321; the item 1322; the production lead time 1323 indicating the period from the start of production to the completion of the production; the production cost 1324 including the assembly cost, processing cost, and production management cost related to production; The average operation rate of the average operation rate of equipment and assembly lines is 1325. In the present embodiment, the unit of the production lead time 1323 is described as a day. In addition, the unit of production cost 1324 is assumed to be ten thousand yen for description.

FIG. 5 is a diagram showing an example of the data structure of the purchasing location information 133 in this embodiment.

The purchase location information 133 includes: the purchase location 1331; the item 1332; the purchase delivery cycle 1333 indicating the period from the order to the storage; the purchase cost 1334 including the purchase price of the item and various expenses related to the purchase; Transaction live 1335 with or without live. In the transaction live 1335, when there is a live transaction, the last transaction date is described. On the other hand, "-" is described in the case where the main purchase place is set in advance, although there is no actual transaction. In the present embodiment, the unit of the procurement delivery cycle 1333 is set to a day for description. In addition, the unit of the purchase cost 1334 is assumed to be ten thousand yen for description.

In addition, in the present embodiment, the example in which the supply chain independent design device 10 holds both the production base information 132 and the purchasing place information 133 is shown, but there is a case where, for example, all parts are produced in the company . The supply chain independent design device 10 may not have the purchasing place information 133 . In addition, for example, the supply chain independent design apparatus 10 may not have the production base information 132 as in the case where the company does not have a production base such as a factory and purchases all components from other companies.

FIG. 6 is a diagram showing an example of the data structure of the priority item order information 134 in this embodiment.

The priority item order information 134 includes items 1341 , ranks 1342 , items 1343 , evaluation values 1344 , and evaluation points 1345 . The value registered in the item 1341 has three types in total, an item to be considered in determining the priority item order, a comprehensive result, and a total of each case.

As important items, in this embodiment, the operation rate of processing equipment, assembly lines, etc., lead times related to production and procurement, and costs related to production and procurement are used. The order of priority varieties can also be determined by items other than these. In addition, as a comprehensive result, in the present embodiment, a comprehensive result is created based on the three indexes of the operation rate, the lead time, and the cost, and the item 1341 is registered as the comprehensive result.

In addition, as each case, a case number is registered in the item 1341, and priority item order information for each case is registered. Here, when the item 1341 is the comprehensive result, since the evaluation value 1344 cannot be calculated, "-" indicating a blank is described. In addition, when the item 1341 is each case, the evaluation value 1344 cannot be calculated in the same way as the comprehensive result. Therefore, a blank "-" is written, and the value of the evaluation point 1345 is the same as the comprehensive result. The form of omission is described with "-".

FIG. 7 is a diagram showing an example of the data structure of the supply chain design plan information 135 of the present embodiment.

The supply chain design scheme information 135 includes a case number 1351 , a design scheme number 1352 , a variety 1353 , a production base/purchase place 1354 , a production/purchase delivery cycle 1355 , a production/purchase cost 1356 , and a negotiation mark 1357 .

Negotiation flag 1357 is a flag indicating whether negotiation with the purchasing place is necessary. For example, in the case of creating based on the production base information 132 and the purchasing place information 133, since an agreement has already been reached with the purchasing place, negotiation is not required. Therefore, in the negotiation flag 1357, "-" indicating that negotiation is not required is written. On the other hand, in the case of the supply chain design plan prepared by the inter-case adjustment unit 123, the production/purchase lead time 1355 and the production/purchase cost 1356 as production and purchasing conditions have not been agreed with the purchasing place, so negotiation is required. Therefore, in order to indicate to the user that negotiation is necessary, the negotiation mark 1357 is written with "N" and a number (for example, "001"). This number is used to identify the related case.

FIG. 8 is a diagram showing an example of the data structure of the supply chain design proposal evaluation result information 136 of the present embodiment.

The supply chain design proposal evaluation result information 136 includes case number 1361, design proposal number 1362, evaluation index: delivery date 1363, evaluation index: target original price 1364, evaluation result: delivery date 1365, and evaluation result: target original price 1366. In this embodiment, the delivery date and the target original price are used as indexes for evaluating the supply chain design of each case, but other indexes may be used.

FIG. 9 is a diagram showing an example of the hardware configuration of the supply chain independent design apparatus 10 according to the present embodiment.

The supply chain independent design device 10 includes an input device 161 , an output device 162 , an external storage device 163 , an arithmetic device 164 , a main storage device 165 , and a communication device 166 , and the respective components are connected by a bus 167 .

The input device 161 is a device that accepts an input operation from a user, and is, for example, a touch panel, a keyboard, a mouse, a microphone, or the like. The function of the input unit 11 is realized by the input device 161 . The output device 162 is a device that performs output processing of data stored in the supply chain independent design device 10 , and is, for example, a display device such as an LCD (Liquid Crystal Display), a printer, or the like. The function of the output unit 14 is realized by the output device 162 .

The external storage device 163 is, for example, a writable and readable storage medium such as an HDD (Hard Disk Drive). The computing device 164 is a central computing device, and executes processing in accordance with a program recorded in the main storage device 165 or the external storage device 163 . The functions of the respective processing units constituting the arithmetic unit 12 are realized by the arithmetic device 164 executing a program.

The main storage device 165 is a storage device such as a RAM (Random Access Memory) or a flash memory, and functions as a storage area for temporarily reading programs and data. The communication device 166 is a device for connecting the supply chain independent design device 10 with the network CN, and is, for example, a communication device such as a NIC (Network Interface Card, network interface card).

The function of the storage unit 13 is realized by the external storage device 163 or the main storage device 165 . In addition, the function of the storage unit 13 may be realized by a storage device on the network CN, or the function of the storage unit 13 may be realized by the database 3 as described above.

It should be noted that the processing of each component of the supply chain independent design apparatus 10 may be executed by one piece of hardware, or may be executed by a plurality of pieces of hardware. In addition, the processing of each component of the supply chain independent design apparatus 10 may be realized by one program, or may be realized by a plurality of programs. The user terminal 2 and the database 3 also have the same hardware configuration as that of the supply chain independent design device 10, and therefore the description is omitted.

FIG. 10 is a flowchart showing an example of the supply chain independent design process of the present embodiment.

This process is started, for example, when the supply chain independent design device 10 receives an instruction to start the supply chain independent design process output from the user terminal 2 . In addition, in the supply chain independent design apparatus 10, this process may be performed regularly, for example every day.

First, the case information input unit 110, the item information input unit 111, the production base information input unit 112, and the purchase location information input unit 113 read input information (step S1). Specifically, the matter information input unit 110 reads, for example, the matter information 130 at the time of processing from the database 3 and stores it in the storage unit 13 . The item information input unit 111 reads, for example, the item information 131 at the time of processing from the database 3 and stores it in the storage unit 13 . The production site information input unit 112 reads, for example, the production site information 132 at the time of processing from the database 3 and stores it in the storage unit 13 . The purchasing location information input unit 113 reads, for example, the purchasing location information 133 at the time of processing from the database 3 and stores it in the storage unit 13 .

Next, the computing unit 12 repeatedly executes the processing from step S2 to step S8 according to the case. The number of cases repeatedly executed becomes the number of records stored in the case number 1301 of the case information 130 .

In the processing from step S2 to step S8, firstly, the priority item order generating unit 120 reads the case information 130, item information 131, production base information 132, and purchasing place information 133, creates priority item order information 134, and stores it in the storage unit 13 (step S3).

Specifically, the priority item order generation unit 120 first calculates the average operation rate/average lead time/average cost for all items included in the item information 131 . Regarding the average operation rate, the average operation rate 1325 of each product is acquired from the production site information 132 ( FIG. 4 ), and the average value thereof is calculated. For example, in the case of the type "MOT-X", it is 90% in the A plant and 90% in the B plant, and their average operation rate is 90%.

As for the average lead time, the production lead time 1323 for each item is acquired from the production base information 132, and the procurement lead time 1333 for each item is acquired from the procurement location information 133 (FIG. 5), and the average value thereof is calculated. For example, in the case of the variety "MOT-X", it becomes the 5th day at the A plant, the 5th day at the B plant, the 10th day at the C company, the 15th day at the D company, and the 30th day at the E company. The average lead time becomes 15 days.

As for the average cost, the production cost 1324 of each item is acquired from the production base information 132, and the procurement cost 1334 of each item is acquired from the procurement location information 133, and the average value thereof is calculated. For example, in the case of the variety "MOT-X", it is 250,000 yen at factory A, 250,000 yen at factory B, 200,000 yen at company C, 150,000 yen at company D, and Company E becomes 50,000 yen, and their average cost becomes 180,000 yen.

Next, the priority item order generation unit 120 converts the evaluation value into an evaluation point for each item calculated previously. In this example, 10 stages of evaluation were performed. When the item 1341 is the operation rate, the maximum is 100% and the minimum is 0%. Therefore, if it is divided into 10 stages, 0% or more and less than 10% are set as 1 point, and 10% or more and less than 20 % becomes 2 points, and 90% or more becomes 10 points. For example, in the case of the type "MOT-X", since the evaluation value 1344 is 90%, the evaluation point 1345 is 10 points.

When the item 1341 is the delivery period, the range of the maximum value and the minimum value of 0 is divided into 10 stages. In this example, since the maximum value is 15, 0 or more and less than 1.5 are set as 1 point, 1.5 or more and less than 3 as 2 points, and 13.5 or more as 10 points. For example, in the case of the type "MOT-X", since the evaluation value 1344 is 15, the evaluation point 1345 is 10 points.

Furthermore, when the item 1341 is the cost, the range of the maximum value and the minimum value of 0 is divided into 10 stages. In this example, since the maximum value is 220,000 yen, 0 or more and less than 2.2 are set as 1 point, 2.2 or more and less than 4.4 as 2 points, and 19.8 or more as 10 points. For example, in the case of the type "MOT-X", since the evaluation value 1344 is 180,000 yen, the evaluation point 1345 is 9 points.

The priority item order generation unit 120 assigns evaluation points to items by item, and then sorts the items in ascending order of the evaluation points to create a rank 1342 and store it in the storage unit 13 as the priority item order information 134 . As a method of converting the evaluation value into the evaluation point, in the present embodiment, the intervals are divided into equal intervals for the 10-stage evaluation, but the evaluation value may be converted into the evaluation point by a method other than the above.

Next, the priority item order generation unit 120 calculates the overall evaluation points based on the evaluation points for each of these items. In this embodiment, the overall evaluation points are calculated by multiplying the respective evaluation points. For example, in the case of the type "MOT-X", the evaluation points 1345 when the item 1341 is the operation rate is 10 points, the evaluation points 1345 when the item 1341 is the delivery cycle is 10 points, and the item 1341 is the cost when the evaluation points are 1345. at 9 o'clock. When these evaluation points are multiplied, 10 points×10 points×9 points=900 points. That is, the evaluation point 1345 when the item 1341 is integrated becomes 900 points.

The priority item order generation unit 120 assigns comprehensive evaluation points to items, and then sorts the evaluation points in ascending order to create a rank 1342 and store it in the storage unit 13 as the priority item order information 134 . As a method of calculating the total evaluation points from the evaluation points of each item, a method of multiplying the evaluation points is adopted. The overall evaluation points are calculated based on the objective evaluation points.

At the end of step S3 , the priority item order generation unit 120 creates priority item order information for each case for all cases registered in the case information 130 . For example, when the case number 1301 is 001 and the specification 1305 is "specification 200", when the item consisting of item information 131 is extracted to illustrate the parent-child relationship, as shown in FIG. 11 .

FIG. 11 is a diagram for explaining an example of the generation process of the supply chain design according to the present embodiment.

The analysis of Figure 11 is as follows. It is shown that the parent variety 1371 "Specification 200" is manufactured from the child varieties 1372 "MKG-X" and "SGY-X", and "MKG-X" is manufactured from "MCH-X" and "GBN-X". In the ascending order of the rank 1342, it is checked whether these items are consistent with the item 1341 of the priority item order information 134, which is registered as the comprehensive item 1343. If they match, the item 1341 is set as the case number 001, and the item 1341 is in the rank 1342 and item 1343. to register. For example, since "MOT-X" whose overall evaluation rank is 1st is also used in the case whose case number 1301 is 001, it is registered in the priority item order information 134 . Next, since "MOT-Y" whose overall evaluation rank is 2 is not used in the case whose case number 1301 is 001, it is not registered in the priority item order as information corresponding to the case whose case number 1301 is 001. Information 134. Through such processing, priority item order information for each case is created and stored in the storage unit 13 .

The priority item order generated as described above indicates the degree to which components of each item are likely to be a factor in generating a supply chain design that does not satisfy at least one of the delivery date and the target cost. For example, when a supply chain design plan for selecting a production base for a part produced at a production base with a high operating rate is created, it turns out that the production base does not have a sufficient operating rate, so the part cannot be accepted. production, the possibility of not meeting the delivery date, etc. becomes high. In addition, when a production base or a procurement location with a long lead time is selected, there is a high possibility that the generated supply chain design will not meet the delivery date. Similarly, when a high-cost production base or procurement location is selected, the possibility that the generated supply chain design does not meet the target original price increases.

Therefore, for example, the order of priority items is determined so that the higher the operation rate of the production base, the higher the ranking is, the longer the lead time of the production base or the purchasing place is, the higher the ranking is, and the higher the cost of the production base or the purchasing place is, the higher the ranking is.

Referring again to FIG. 10 . Next, the computing unit 12 repeatedly executes the processing from step S4 to step S6 in the order of priority items. The priority item order is an order of items 1343 obtained by sorting records whose item 1341 of the priority item order information 134 matches the case number in ascending order of the rank 1342 .

In step S5 , the supply chain design proposal generation unit 121 reads the item information 131 , the production base information 132 , and the purchasing place information 133 , creates the supply chain design proposal information 135 and stores it in the storage unit 13 .

Specifically, for example, when the case number 1301 is 001, the item 1341 of the priority item order information 134 is the item number 1341 with the case number 001 and the item 1343 in the first rank 1342 is "MOT-X". Therefore, the supply chain design The plan generation unit 121 initially decides the production base/purchasing place of "MOT-X".

First, the supply chain design proposal generation unit 121 extracts a record matching the type 1343 of the type 1322 of the production base information 132 and the type 1332 of the purchasing place information 133 . When the item 1343 is “MOT-X”, “Factory A” and “Factory B” are extracted from the production base information 132 as the factory 1321 , and “Company C”, “Company D” and “Company C” are extracted from the source information 133 . Company E" as the place of purchase 1331. The supply chain design proposal generation unit 121 evaluates whether the delivery date is satisfied at this time point for the supply chain design proposals of the five modes, and removes the supply chain design proposals that do not meet the delivery date from the supply chain design proposal at this time point. exclude.

The supply chain design proposal generation unit 121 first calculates the shortest production delivery in the case where internal work is performed on all the upper-level items of "MOT-X" (in the example of FIG. 11 , "MCH-X" and "MKG-X") Cycle, if the production base is "A factory" or "B factory", add the production delivery cycle to its value, and if the purchasing place is "C Company", "D Company" or "E Company", add it to the value. On the procurement delivery cycle, determine whether the current + delivery cycle meets the delivery date.

In the above example, the shortest lead time is 3 days for "MCH-X" + 1 day for "MKG-X" when in-house work is performed on all high-level items of "MOT-X", and the total becomes 4 day. According to the production base information 132 and the purchasing place information 133, the delivery cycles of Factory A, Factory B, Company C, Company D, and Company E are 5 days, 5 days, 10 days, 15 days, and 30 days, respectively. In addition, according to the case information 130, the delivery date is 2019/6/1. In the case of current 2019/5/1, if purchasing from company E, it will be 4 days + 30 days = 34 days, and the completion date will be 2019/5/1 + 34 days = 2019/6/3, not satisfied Delivery dates. Therefore, the supply chain design proposal generation unit 121 excludes the E company that does not meet the delivery date at this point in time, and based on the supply chain design proposals of the remaining four modes (ie, A factory, B factory, C company, and D company), Carry out the supply chain design for the next priority variety.

Next, the supply chain design proposal generation unit 121 determines that the item 1341 of the priority item order information 134 is the production base/purchasing place of the item 1343 "MCH-X" whose case number is 001 and the priority 1342 is 2nd. In the case of “MCH-X”, the A factory and the B factory are extracted from the production base information 132 as the factory 1321 , and the B company is extracted from the purchase location information 133 as the purchase location 1331 .

Here, in the case of purchasing "MCH-X" from Company B, the "MOT-X" of the subcomponent is included in the "MCH-X" purchased from Company B (that is, its cost is also included in the "MCH-X" purchased from Company B). MCH-X"), therefore, there is no need to separately manufacture "MOT-X" in our company or purchase "MOT-X" from another company. Therefore, in the case of purchasing "MCH-X" from Company B, there is no need to select the above-mentioned four modes of Factory A, Factory B, Company C, and Company D as the production base or purchasing place of "MOT-X".

Therefore, consider a combination of the two modes of selecting "MCH-X" from Factory A and Factory B and the four modes of selecting the previous "MOT-X" from Factory A, Factory B, Company C, and Company D. A total of nine supply chain designs for the model and the model for purchasing "MCH-X" from Company B.

Similar to the case of "MOT-X" described above, the supply chain design proposal generation unit 121 evaluates whether the delivery date is satisfied at this point in time for the supply chain design proposals of the nine patterns, and will not supply the supply that does not satisfy the delivery date. The chain design is excluded from the supply chain design at this point in time. For example, if the internal operation is performed on "MCH-X" in Factory A and the internal operation on "MOT-X" is also performed in Factory A, then the internal operation is performed on all the upper-level items of "MCH-X". The shortest production lead time is obtained by adding 1 day of "MKG-X" to the production lead time of "MCH-X" of 3 days at Factory A and "MOT-X" of 5 days of production lead time of Factory A. A total of 9 days, in the current case of 2019/5/1, there are enough days until the delivery date 2019/6/1. The supply chain design proposal generation unit 121 performs the same calculation for the remaining eight patterns, evaluates whether the delivery date is satisfied at this point in time, and removes the supply chain design proposal that does not satisfy the delivery date from the supply chain design proposal at this point in time. exclude.

The supply chain design proposal generation unit 121 repeats the above-mentioned processing until the item 1341 of the priority item order information 134 is the item with the case number 001 and the order 1342 is the lowest item, thereby generating the supply chain design proposal information 135 for each case. and stored in the storage unit 13 .

As already explained, the priority item order is set so that the components of each item are more likely to be a factor in generating a supply chain design that does not satisfy at least one of the delivery date and the target original price, and the higher the priority. Therefore, by generating the supply chain design in the order of priority items, in the process of repeatedly executing step S5 in the loop of steps S4 to S6, it is possible to find out relatively early (that is, at the stage when the number of repetitions at the end is still small). Supply chain designs that do not meet delivery dates. By excluding such a supply chain design solution from the processing object in advance, useless calculations can be omitted and processing time can be shortened.

In the above-mentioned example, whether or not the delivery date is satisfied is determined based on the delivery period, but similarly, whether the target original price is satisfied may be determined based on the cost, and if the target original price is not satisfied, the plan is excluded. In addition, both the determination of whether the delivery date is satisfied based on the delivery cycle and the determination of whether the target original price is satisfied based on the cost may be performed. In addition, in the above-mentioned example, when the delivery date is not met, the plan is excluded, but it may be allowed to exceed a certain level, and when the delivery date exceeds a predetermined value or more, the plan is excluded. The same goes for the cost. Alternatively, it is also possible to leave it without excluding a plan in which only either the delivery date or the target original price is exceeded. As a result, even if it is a supply chain design that does not meet the delivery date and other requirements, it is possible to leave a supply chain design that can be adjusted later.

In the above-mentioned embodiment, only one mode is used to describe the production conditions such as the production lead time and production cost, and the procurement conditions such as the procurement lead time and the procurement cost when creating the combined mode of the production base or the procurement place. Multiple modes are also possible. In this case, a pattern is created by combining bases and conditions.

After the repetitive processing of steps S4 to S6, the supply chain design proposal evaluation unit 122 reads the supply chain design proposal information 135, evaluates whether the evaluation indicators such as delivery date and original price reach the target value, and generates a supply chain design proposal as the evaluation result. The evaluation result information 136 is stored in the storage unit 13 (step S7).

Specifically, the supply chain design proposal evaluation unit 122 extracts the record in which the case number 1351 of the supply chain design proposal information 135 matches the item, and calculates the total lead time and total cost for each design proposal number 1352 . The lead time of each product is calculated by adding the maximum lead time of the child product to its own lead time. The cost of each item is calculated by adding the total value of the cost of the sub-items to its own cost.

FIG. 12 is a diagram for explaining an example of the evaluation process of the supply chain design plan of the present embodiment.

Specifically, FIG. 12 shows an example in which the lead time and cost of “MCH-X” are calculated for the design proposal number 1 of the case number 001 . The supply chain design proposal evaluation unit 122 first calculates an evaluation value 1381 for each item. For example, in the case of "MCH-X", according to the supply chain design proposal information 135, when the production base is Factory A, the production lead time is 2 days and the production cost is 200,000 yen.

The supply chain design proposal evaluation unit 122 determines the range 1382 of the constituent items of each item after calculating the individual evaluation value of each item. For example, in the case of "BAC-X", the constituent species is "ROH-A". In the case of "MCH-X", the constituent varieties are "BAC-X", "ROH-A", "MOT-X", "BRK-X" and "ROH-C". After the range 1382 of the constituent items of each item is determined, the evaluation value 1383 of the entire constituent item is calculated.

For example, in the case of "BAC-X", the procurement lead time of "ROH-A" is 7 days + the production lead time of "BAC-X" is 2 days = 9 days, and the production cost is also calculated as 130,000. JPY. In addition, in the case of "MCH-X", the lead time for "BAC-X" as a component item is 9 days, the procurement lead time for "MOT-X" is 10 days, and the lead time for "BRK-X" is 11 days The production lead time of "MCH-X" itself (that is, the number of days from the start of production of "MCH-X" to the end of production when all the constituent varieties are gathered together) is 2 days. The overall delivery cycle of MCH-X" is MAX (9 days, 10 days, 11 days) + 2 days = 13 days. The cost is 200,000 yen + 130,000 yen + 200,000 yen + 200,000 yen = 730,000 yen because it is simply calculated.

The supply chain design proposal evaluation unit 122 performs the same processing as described above for components other than "MCH-X", and calculates the lead time and cost of "specification 200" of the highest-level BOM item. Then, the calculation result is compared with the target value of the evaluation index to determine whether or not the target value has been reached, thereby generating supply chain design proposal evaluation result information 136 for each case and storing it in the storage unit 13 .

Referring again to FIG. 10 . After the repetitive processing of steps S2 to S8, the supply chain design proposal evaluation unit 122 determines whether or not the target value of the evaluation index is reached in all cases (step S9). When the supply chain design proposal evaluation unit 122 determines that the target value of the evaluation index has not been reached in all the cases (that is, the target value of the evaluation index has not been reached in at least one case) (in the case of “NO” in step S9 ), make the The process proceeds to step S10. When the supply chain design proposal evaluation unit 122 determines that the target value of the evaluation index is reached in all cases (in the case of YES in step S9 ), the process proceeds to step S11 .

Next, the inter-case adjustment unit 123 reads the supply chain design proposal information 135 and the supply chain design proposal evaluation result information 136, and performs individual optimization for each case, and generates and evaluates the target that the evaluation indicators such as delivery date and original price cannot be achieved. The adjustment scheme for the case of the value. Then, the inter-case adjustment unit 123 adds the result of the generation and evaluation to the supply chain design plan information 135 and the supply chain design plan evaluation result information 136, and stores them in the storage unit 13 (step S10).

Specifically, the case-to-case adjustment unit 123 first generates a list of types, production bases/purchases, and periods for cases that do not reach the target value of the evaluation index based on the supply chain design proposal information 135 and the supply chain design proposal evaluation result information 136 . A combination of supply chain design solutions for cases with a high degree of commonality. For example, the higher the proportion of the parts of the same variety in the parts included in the two cases, or the higher the proportion of the parts in the two cases obtained from the same production base or procurement place, or the higher the proportion of the parts in the two cases. The closer the delivery date, the higher the commonality.

FIG. 13 is a diagram for explaining an example of the case-to-case adjustment processing in this embodiment.

The combination table 1391 in FIG. 13 is an example of generating a combination of supply chain design proposals for cases with a high degree of commonality. Design proposal numbers 1 and 2 of case number 001 and design proposal numbers 1 and 2 of case number 002 are obtained from C company. Or company D purchased BAC-X, which is a supply chain design plan for a case with a high degree of commonality between the product, the place of purchase, and the period. In these four scenarios, the delivery date meets the target value but the original price does not meet the target value. In response to this, the inter-issue adjustment unit 123 generates production/purchasing/distribution conditions that satisfy the target value of the original price.

For example, when looking at the variety BAC-X again, the delivery date is met even if the procurement lead time is 15 days. In this regard, under the current situation, although the procurement lead time of Company C is 10 days, instead of extending it to 15 days, try to negotiate whether the current procurement cost can be reduced by 200,000 yen. The target original price of case No. 001 exceeds 50,000 yen, and the target original price of case No. 002 exceeds 40,000 yen. Therefore, the inter-case adjustment section 123 generates a proposal to make the procurement cost 150,000 yen lower than the current situation by 50,000 yen , so that no matter which case meets the target original price.

The supply chain design proposal evaluation unit 122 re-evaluates the supply chain design proposal 1392 created by the inter-case adjustment unit 123 . Then, the created new supply chain design proposal and the supply chain design proposal evaluation result are added to the supply chain design proposal information 135 and the supply chain design proposal evaluation result information 136 and stored in the storage unit 13 .

In the above example, the multiple supply chain design proposals produced all meet the delivery date and do not meet the target original price. Therefore, the inter-case adjustment unit 123 generates an adjustment plan that reduces the cost instead of extending the lead time. On the other hand, if the prepared supply chain design plan does not meet the delivery date and meets the target original price, the inter-case adjustment unit 123 can generate an adjustment plan that allows for an increase in cost instead of shortening the lead time.

In this way, where one of the multiple requirements is satisfied and the other is not, by relaxing the conditions (eg lead times) associated with the requirements of the satisfied party (eg the delivery date) and tightening the requirements of the non-satisfied party conditions (such as cost) associated with the requirements (such as target original price), and can generate an adjustment plan that meets all the requirements and is easily accepted through negotiation.

In addition, in the above example, by extending the procurement lead time of Company C from 10 days to 15 days, the lead time of the same component in other supply chain design schemes that satisfy the delivery date (in the above example: Company D's procurement lead time) is set as an upper limit and an adjustment plan is designed, so that an adjustment plan with a high possibility of being realized can be generated. The same is true when an increase in cost is allowed to reduce the lead time, and when there is another supply chain design that satisfies the target original price, an adjustment can be made by setting the value of the cost of the same part of the design as an upper limit Program.

It should be noted that, in the above-mentioned example, the inter-case adjustment unit 123 generates, for the supply chain design plans of a plurality of cases, changes in production conditions or procurement for parts of the same type produced at the same production base or purchased from the same source. conditional adjustment. However, the inter-case adjustment unit 123 may generate an adjustment plan for one supply chain design plan for one case. In this case, for example, as described above, instead of extending the lead time, it is possible to generate an adjustment plan that can be accepted by negotiation, such as cost reduction.

However, as described above, when an adjustment plan is created over a plurality of cases, especially when cost reduction is achieved, it is considered that the possibility of being accepted by the effect of mass production becomes high. In addition, it is also possible for the ordering party to propose an adjustment plan that can collectively eliminate the same problems related to the delivery date or the target original price for a plurality of cases with a high degree of commonality, thereby reducing the burden of processing.

Referring again to FIG. 10 . Finally, the supply chain design proposal display unit 140 generates a supply chain design result screen based on the case information 130, the supply chain design proposal information 135, and the supply chain design proposal evaluation result information 136, and sends it to the user terminal 2 (step S11). After that, the arithmetic unit 12 ends the processing of this flowchart.

FIG. 14 is a diagram showing an example of the supply chain design result screen 141 of the present embodiment.

The supply chain design result screen 141 includes a case number selection button 1411 , a case information table 1412 , a supply chain design proposal display area 1413 , a design proposal number selection button 1414 , a specification information scroll bar 1415 , and an inter-case adjustment information table 1416 .

The matter number selection button 1411 displays all the matter numbers included in the matter information 130 in a selectable manner. The case information 130 related to the selected case number is displayed on the case information table 1412 . Then, the supply chain design proposal information 135 related to the selected case number is displayed in the supply chain design proposal display area 1413 . The design number 1352 of the supply chain design information 135 related to the selected case number is displayed on the design number selection button 1414, and these design numbers 1352 can be selected.

Then, acquire the variety, quantity, production base/purchasing place, production/purchasing delivery cycle, production/purchasing cost, and negotiation mark related to the selected design proposal number from the supply chain design proposal information 135, and display the information in the Specification information field 14131. Then, information indicating whether the evaluation indexes such as delivery date and original price related to the selected design plan number have reached the target value is obtained from the supply chain design proposal evaluation result information 136 , and displayed in the evaluation index information column 14132 . In addition, the content displayed in the specification information field 14131 can be switched by the specification information scroll bar 1415.

Finally, when there is a negotiation mark of the item related to the design scheme number selected by the scheme number selection button 1414, the case number, the scheme number, Variety, quantity, production base/purchasing place, production/purchasing lead time, and production/purchasing cost, and display these information in the inter-case adjustment information table 1416. In addition, the form of representing the supply chain design result is not limited to the form shown in FIG. 14 .

According to the present embodiment, it is possible to derive a case-by-case supply chain design plan from a large combination of purchasing locations/production locations and the like in a short period of time. In addition, it is possible to generate adjustment plans for cases that cannot reach the target values of evaluation indicators such as delivery date and original price through individual optimization for each case. Thereby, the improvement of the delivery date compliance rate and the improvement of a yield can be aimed at.

Representative examples of the embodiments of the present invention described above are summarized as follows. That is, a supply chain design system (for example, the supply chain independent design system 1 in FIG. 1 ) according to one embodiment of the present invention includes a calculation unit (for example, the calculation unit 12 ) and a storage unit (for example, the storage unit 13 ), and the storage unit holds production base information ( For example, at least one of production base information 132) and purchasing place information (such as purchasing place information 133), case information (such as case information 130), and item information (such as item information 131), the case information includes each case for which an order is received The specifications of the delivered goods (for example, specification 1305) and the evaluation criteria of the supply chain design plan for each case (for example, the delivery date 1303 and the target original price 1304, etc.), and the type information includes the type of the components that make up the delivered goods (for example, the parent type 1311) and sub-variety 1312), the production base information includes the types of components produced at each production base (such as variety 1322), and production conditions (such as production lead time 1323 and production cost 1324, etc.), and the purchasing place information includes purchasing from each purchasing place. The type of parts (for example, type 1332), and the procurement conditions (for example, procurement lead time 1333 and procurement cost 1334, etc.), the calculation unit generates, for each case, one or more production bases or procurement places including each component that constitutes the delivery. (for example, steps S4 to S6), each supply chain design scheme is evaluated based on the evaluation criteria (for example, step S9), and for the supply chain design schemes that do not meet the evaluation criteria, a modified production condition or procurement condition is generated. Adjust the plan so as to satisfy the evaluation criteria (eg, step S10 ), and output the generated adjustment plan (eg, step S11 ).

As a result, it is possible to derive a case-by-case supply chain design that improves the delivery date compliance rate/yield.

Here, when the supply chain design proposals of a plurality of cases each of which does not satisfy the evaluation criteria include components of the same type produced at the same production base or procured from the same procurement place, the calculation unit may generate the same type of components. An adjustment plan (for example, the adjustment plan shown in FIG. 13 ) in which the production conditions or procurement conditions of the parts are changed in the same way.

In this case, the calculation unit may generate an adjustment in which the production conditions or procurement conditions are changed in the same way for the supply chain design proposals of the plurality of cases that do not satisfy the evaluation criteria, respectively, related to the plurality of cases with a high degree of commonality. Program.

In addition, the computing unit may calculate the degree of commonality based on at least one of the types of components included in the delivery, the production base or purchasing place of the components, and the delivery date of the delivery.

This makes it easy for suppliers to accept due to the effect of mass production and the like, and it is possible to generate an adjustment plan that is easy to negotiate.

In addition, based on the item information, the item information, the production base information, and the purchasing place information, the calculation unit may determine a priority order (for example, rank 1342) for the item of the components constituting the delivered goods so that the easier it is to generate The product that does not meet the evaluation criteria is the main reason for the unplanned supply chain, and the higher the ranking, the calculation unit determines the production base or procurement place of the components of each product in order of priority, and generates a supply chain design plan.

In this case, the production base information may include the types of parts produced at each production base (for example, type 1322 ), and the production lead time, production cost, and operation rate for each type of parts (for example, production lead time 1323 , production lead time 1323 , production cost 1324 and average operation rate 1325), the source of purchase information includes the types of components procured from each source (for example, type 1332), and the procurement lead time and procurement cost for each type of component (such as procurement lead time 1333 and procurement costs) 1334), the calculation unit determines the priority order (for example, the order of 1342) so that the longer the production lead time or the procurement lead time of the component is, the higher the priority is, and the higher the production cost or the procurement cost of the component is, the higher the priority is, and the factory that produces the component is higher. The higher the operating rate, the higher the position.

As a result, supply chain design solutions that do not meet the required conditions (that is, have a low possibility of being adopted) are excluded from processing objects in advance, thus avoiding useless processing and shortening the overall processing time.

In addition, the evaluation criteria of the supply chain design plan for each case may include the delivery date of the delivered goods (eg, the delivery date 1303 ) and the target original price (eg, the target original price 1304 ), and the production conditions may include the The production lead time and production cost, and the procurement conditions include the procurement lead time and procurement cost of each type of component. When the plan does not satisfy at least one of the delivery date of the delivery item and the target original price, it is determined that the evaluation criteria are not satisfied (eg, step S9 ).

Thereby, the quality of the generated supply chain design is appropriately determined.

In this case, when the supply chain design proposal that does not meet the evaluation criteria meets the delivery date and does not meet the target original price, the calculation unit may generate an adjustment to extend the production lead time or the procurement lead time to reduce the production cost or the procurement cost. In the scenario (eg, Fig. 13 ), if the supply chain design solution that does not meet the evaluation criteria does not meet the delivery date and meets the target original price, an adjustment plan is generated that shortens the production lead time or procurement lead time and increases the production cost or procurement cost.

In addition, at this time, the computing unit may generate a plurality of the supply chain design proposals for each case, and for any type of component, the production lead time or the procurement lead time may be extended to reduce the production cost or the procurement cost. In the case of an adjustment plan, the maximum value of the production lead time or the procurement lead time of the type of the component included in the supply chain design plan that satisfies the delivery date among the plurality of supply chain design plans is set as the upper limit and extended. The production lead time or the procurement lead cycle (for example, Figure 13), for any type of component, in the case of generating an adjustment plan that shortens the production lead time or the procurement lead time and increases the production cost or the procurement cost, multiple supply The maximum value of the production cost or the procurement cost of the type of the component included in the supply chain design solution that satisfies the target original price in the chain design solution is set as the upper limit to increase the production cost or the procurement cost.

Thereby, it is possible to generate an adjustment plan with a high possibility of being realized.
