Description

Supply chain design system and supply chain design method

Technical Field

The present invention relates to a technique for designing a supply chain for each case.

Background

In a large-scale customized product in which a product-type customized product is realized with mass productivity, it is desirable to perform an independent supply chain design for deciding a place of purchase/a place of production and the like on a delivery site/a date of delivery/a target original price/specifications basis for each case so as to comply with the date of delivery and bring about high profit. However, due to the enormous combination of procurement/production locations, etc., the supply chain is predetermined because of the difficulty in designing each case. Therefore, the date of delivery compliance rate/profitability is lowered because the demand cannot follow changes in business environment or changes in demand. In contrast, it is effective to derive a case-by-case supply chain design from a large combination in a short time for each case.

As a technique for deriving a supply chain design scheme that follows changes in business environments and changes in demand, there are conventional techniques as described in patent documents 1 to 3 below.

Patent document 1 describes a technique of "scheduling in consideration of outsourced equipment when there is an order for which delivery date is not secured" (see abstract of the specification).

Patent document 2 describes a technique of "calculating a recommendation level of a product to be preferentially negotiated for purchase unit price" (see abstract of the specification).

Patent document 3 describes a technique of visually and easily setting information necessary for generating a common transport path (see abstract of the specification).

Disclosure of Invention

Problems to be solved by the invention

The technique described in patent document 1 has the following functions: and under the condition that the evaluation indexes such as delivery date and the like in internal operation do not reach the standard, deriving a scheme for researching outsourcing processing. However, since the product is requested to be processed only by another company, it is necessary to separately determine where to produce or from which to purchase the component such as the material and the part of the product. That is, even if the item is requested to be processed by another company, the parts list (BOM: Bill Of Materials) is not changed. In the manufacturing industry, the variety may be purchased from other companies in addition to the case of performing outsourcing processing on the variety. When purchased by another company, the material, parts, and the like of the item are also produced/purchased by another company, and therefore, it is not necessary to conduct supply chain research of the material and parts of the item. In this case, the material and parts of this variety are excluded from the BOM. Patent document 1 does not address such a situation. Further, since all the studies of switching between the internal work and the external work are combined, it is considered that it is difficult to derive the internal work and the external work in a short time.

Further, the technique described in patent document 2 has a function of evaluating the negotiation room for the purchase price of the item based on the past order history information, but cannot create a transaction condition for purchasing at a low price and a short delivery date by adjustment over a plurality of cases.

In addition, in the technique described in patent document 3, a common transport path can be generated and an evaluation index value can be evaluated with respect to a common transport condition input from a user, but the common transport condition itself cannot be automatically generated.

In contrast, the object of the invention is to derive a case-specific supply chain design from a large number of combinations in a short time. In addition, production, procurement, and delivery conditions are created for cases in which the evaluation index values such as delivery date and original price have not reached the target values in case-independent design, so that the target values can be achieved.

Means for solving the problems

In order to solve at least one of the above problems, a supply chain design system according to the present invention includes a calculation unit and a storage unit, wherein the storage unit holds at least one of production site information and purchase site information, case information including a specification of a delivered item for each case for which an order is received and an evaluation criterion of a supply chain design plan for each case, the case information includes a variety of a component constituting the delivered item, the production site information includes a variety of a component produced at each production site and a production condition, the purchase site information includes a variety of a component purchased from each purchase site and a purchase condition, the calculation unit generates one or more supply chain design plans including a production site or a site of each component constituting the delivered item for each case, and evaluates each supply chain design plan based on the evaluation criterion, and generating an adjustment scheme for changing the production condition or the procurement condition for the supply chain design scheme which does not satisfy the evaluation criterion, so that the generated adjustment scheme is output when the evaluation criterion is satisfied.

Effects of the invention

According to one aspect of the present invention, a case-by-case supply chain design scheme with improved delivery date compliance/profitability can be derived.

Problems, structures, and effects other than those described above will become apparent from the following description of the embodiments.

Detailed Description

The following examples are illustrative, but the scope of the present invention is not limited to the examples.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, a case-by-case supply chain design of a target article is automatically generated. Examples of the target articles include elevator devices such as elevators and escalators, motor products, machine products, automobiles, electric trains, airplanes, generators, controllers, control boards, stocker devices, Network storages such as NAS (Network Attached Storage), servers, and water treatment devices.

Fig. 1 is a diagram showing an example of functional blocks of the supply chain independent design system 1 according to the present embodiment.

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

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

The network CN connects the user terminal 2, the database 3, and the supply chain independent design apparatus 10 in a communicable manner. The Network CN is, for example, any of communication networks such as a LAN (Local Area Network), a WAN (Wide Area Network), a VPN (Virtual Private Network), or the internet that uses a general public line for a part or all of them.

The supply chain independent design apparatus 10 is an information processing apparatus 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 receives information input to the supply chain independent design apparatus 10 via an input device such as a keyboard or a touch panel. The calculation unit 12 derives a case-by-case supply chain design plan. 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 to and from another device connected via the network CN.

The input unit 11 includes a case information input unit 110, a variety information input unit 111, a production base information input unit 112, and a purchase 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 procurement location information input unit 113 acquire necessary information from the user terminal 2 or the database 3 via the respective communication units 15, and store the acquired information in the storage unit 13.

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

The priority item order generating unit 120 generates a priority item order when designing a supply chain. In the supply chain design, as described above, when the item is purchased by switching to the external operation (i.e., purchase based on purchase from another company) without generating the item in the internal operation (i.e., production in the production base of the own company), it is not necessary to study the item of the lower layer. Therefore, studies are generally conducted from the top variety of BOMs.

However, for example, in the lower-layer product, the delivery date may not be satisfied due to the production or purchase status, and therefore, the internal work is abandoned, and rework such as a change of the production base of the upper-layer product or a review of the external work is caused. In order to prevent the occurrence of rework, it is desirable to create a priority item order from the load status of the production site and the transaction conditions of the place of purchase, and study the supply chain design according to the priority item order. In order to reduce the rework when performing such supply chain design, there is a priority item order generation unit 120.

The priority item order generation unit 120 calculates evaluation indexes for each item, generates a priority item order by integrating the evaluation indexes, and generates a priority item order for each case by referring to the integration 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 plan generating unit 121 generates a plurality of supply chain design plans for determining production bases/production conditions and procurement locations/procurement conditions for each of the cases in the order of the priority type of each case. The supply chain design plan generating unit 121 stores the created supply chain design plan information in the storage unit 13.

The supply chain design plan evaluation unit 122 calculates an evaluation index value such as a delivery date and an original price for the supply chain design plan information created by the supply chain design plan creation unit 121. The supply chain design evaluation unit 122 stores the created supply chain design evaluation result information in the storage unit 13.

The case adjustment unit 123 confirms the supply chain design plan evaluation result of each case, extracts cases whose evaluation index values such as delivery date and original price have not reached the target values, and generates production/procurement/distribution conditions satisfying the target values of the evaluation indexes. At this time, the inter-case adjustment unit 123 not only generates production, procurement, and distribution conditions satisfying the target values of the evaluation indexes for each case, but also performs a study of integrating a plurality of cases.

For example, if there are a plurality of cases purchased from the same category, the price can be reduced by performing collective purchasing in which the purchase locations are matched. In addition, if there are a plurality of cases to be delivered to the same area at the same time, the price can be reduced by performing the collective delivery such that the delivery dates coincide with each other. If there are a plurality of cases in which the same type of article is subjected to internal work, the price can be reduced by performing concentrated production in which the production sites are matched.

In this way, by performing adjustment such as collective purchase/collective distribution/collective production across cases (that is, between a plurality of cases), the possibility of achieving a short delivery date/low price is sought, and a supply chain design plan satisfying the target value of the evaluation index is generated. The inter-case adjustment unit 123 stores the newly created supply chain design plan information and the supply chain design plan evaluation result information in the storage unit 13.

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

The case information 130 is information related to a case that the company receives an order from a customer.

The item information 131 is BOM information required for manufacturing the target object.

The production site information 132 is information related to the manufacture of the company.

The purchase place information 133 is information (purchase delivery period, purchase charge, etc.) related to purchase between the supplier and the company. At the processing start time, the purchasing place information 133 is set based on the past transaction status and agreement with the supplier.

The priority item ranking information 134 is the priority item ranking information and the priority item ranking information for each case in the evaluation indexes for each item and the integrated result of the evaluation indexes.

Supply chain design information 135 is the supply chain design information for each case. The supply chain design information includes production base/production conditions, procurement location/procurement conditions of each product constituting the specification, and identification information indicating whether or not the production conditions/procurement conditions are different from the current actual transaction situation and principal value and need to be re-negotiated. In addition, a plurality of supply chain designs are stored for each case.

The supply chain design plan evaluation result information 136 is result information in which whether or not the supply chain design plan for each case has reached the target value of the evaluation index such as the delivery date and the original price is evaluated.

The output unit 14 is provided with a supply chain design plan display unit 140.

The supply chain design plan display unit 140 acquires the supply chain design plan and evaluation result information for each case stored in the case information 130, the supply chain design plan information 135, and the supply chain design plan evaluation result information 136, and transmits the acquired information to the user terminal 2 via the communication unit 15. These pieces of information are displayed on the user terminal 2. On the evaluation result screen, a supply chain design plan for determining a production base/production condition and a procurement location/procurement condition of each product, a target value of an evaluation index value such as a delivery date and an original price at that time, and information indicating whether or not the evaluation index value has been reached are displayed for each case.

In the present embodiment, the user terminal 2 and the database 3 are provided outside the supply chain independent design apparatus 10, but the configuration 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 calculation unit 12 may acquire the information from the database 3 as needed. The device configuration of the supply chain independent design system 1 can be appropriately changed as long as the object of the present embodiment is not impaired.

Fig. 2 is a diagram showing an example of the data structure of the case information 130 according to the present embodiment.

The case information 130 includes a case number 1301, a delivery place 1302, a delivery date 1303, a target price 1304, a specification 1305, and a quantity 1306. The specification 1305 stores the name of the top item of BOM. In this embodiment, the unit of the target original price 1304 is described as ten thousand yen.

Fig. 3 is a diagram showing an example of the data structure of the item information 131 according to 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 normal BOM information.

Fig. 4 is a diagram showing an example of a data structure of the production site information 132 according to the present embodiment.

The production base information 132 includes: a plant 1321; variety 1322; a production lead time 1323 indicating a period from the start of production to the completion of production; production costs 1324 including assembly costs, processing costs, and production management costs associated with production; and an average operation rate 1325 indicating an average operation rate of the processing equipment, the assembly line, and the like. In the present embodiment, the unit of the production lead time 1323 is described as a day. The unit of the production cost 1324 is described as ten thousand yen.

Fig. 5 is a diagram showing an example of the data structure of the procurement location information 133 according to the present embodiment.

The procurement location information 133 includes: a procurement location 1331; variety 1332; a purchase delivery cycle 1333 indicating the period from ordering to warehousing; purchase cost 1334 including various expenses related to the purchase price and purchase of the variety; and a transaction status 1335 indicating the presence or absence of a transaction status. The transaction status 1335 records the final transaction date when the transaction status exists. On the other hand, if the purchase place is set mainly in advance although there is no actual transaction, a "-" is described. In the present embodiment, the unit of the purchase delivery cycle 1333 will be described as day. The unit of the purchase cost 1334 will be described as ten thousand yen.

In the present embodiment, the example in which the supply chain independent design apparatus 10 holds both the production site information 132 and the procurement site information 133 is shown, but for example, as in the case where all components are produced by the company, the supply chain independent design apparatus 10 may not have the procurement site information 133. For example, the supply chain independent design apparatus 10 may not have the production site information 132, as in the case where the present company does not have a production site such as a factory and all components are purchased from another company.

Fig. 6 is a diagram showing an example of the data structure of the priority item order information 134 according to the present embodiment.

The priority item order information 134 includes an item 1341, a rank 1342, an item 1343, an evaluation value 1344, and an evaluation point 1345. The value registered in the item 1341 includes three types in total, which are items to be regarded as important in determining the priority item order, the integrated result, and each case.

As important items, in the present embodiment, the operation rate of the processing equipment, the assembly line, and the like, the lead time related to production and procurement, and the cost related to production and procurement are used. The order of the preferred varieties may be determined by other items. In the present embodiment, the integrated result is created from three indexes, i.e., the operation rate, the lead time, and the cost, and item 1341 is registered as integrated.

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 integrated result, the evaluation value 1344 cannot be calculated, and thus "-" indicating a blank is described. Note that, when the item 1341 is each case, since the evaluation value 1344 cannot be calculated as in the case of the integrated result, a "-" indicating a blank is described, and since the value of the evaluation point 1345 is the same as the integrated result, a "-" is described in an omitted manner.

Fig. 7 is a diagram showing an example of the data structure of the supply chain design scenario information 135 according to the present embodiment.

The supply chain design information 135 includes a case number 1351, a design number 1352, a variety 1353, a production base/procurement location 1354, a production/procurement lead time 1355, a production/procurement cost 1356, and an engagement identification 1357.

The negotiation flag 1357 is a flag indicating whether or not a negotiation with the place of purchase is required. For example, when the information is created based on the production base information 132 and the procurement location information 133, the information is already agreed with the procurement location, and thus no negotiation is required. Therefore, the negotiation flag 1357 records "-" indicating that no negotiation is necessary. On the other hand, in the case of the supply chain design created by the inter-case adjustment unit 123, the production/purchase lead time 1355 and the production/purchase cost 1356, which are production and purchase conditions, do not agree with the place of purchase, and therefore, an intervention is required. Therefore, in order to indicate to the user that an engagement is required, the engagement flag 1357 records "N" and a number (for example, "001"). This number is used to identify the associated case.

Fig. 8 is a diagram showing an example of the data structure of the supply chain design scenario evaluation result information 136 according to the present embodiment.

The supply chain design plan evaluation result information 136 includes a case number 1361, a design plan number 1362, and evaluation indexes: delivery date 1363, evaluation index: target original price 1364, evaluation result: delivery date 1365, and evaluation result: target original price 1366. In the present embodiment, the delivery date and the target original price are used as the index 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 of the present embodiment.

The supply chain independent design apparatus 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 each component is connected by a bus 167.

The input device 161 is a device that receives 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) or a printer. The function of the output unit 14 is realized by the output device 162.

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

The main Memory 165 is a Memory 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 to the Network CN, and is a communication device such as a NIC (Network Interface Card).

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

The processing of each component of the supply chain independent design apparatus 10 may be executed by one hardware or by a plurality of hardware. 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 the supply chain independent design apparatus 10, and therefore, the description thereof is omitted.

For example, when the supply chain independent design apparatus 10 receives an instruction to start the supply chain independent design process output from the user terminal 2, the present process is started. The present process may be performed periodically, for example, every day in the supply chain independent design apparatus 10.

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

Subsequently, the arithmetic unit 12 repeatedly executes the processing of step S2 to step S8 for each case. The number of repeatedly executed cases is the number of records stored in the case number 1301 of the case information 130.

In the processing from step S2 to step S8, initially, the priority item ranking generation unit 120 reads the case information 130, the item information 131, the production base information 132, and the procurement location information 133, creates priority item ranking information 134, and stores the priority item ranking information 134 in the storage unit 13 (step S3).

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

As for the average lead time, the production lead time 1323 of each item is acquired from the production base information 132, and the purchase lead time 1333 of each item is acquired from the purchase place information 133 (fig. 5), and the average value thereof is calculated. For example, in the case of the breed "MOT-X", the lead time is 5 days in the a factory, 5 days in the B factory, 10 days in the C company, 15 days in the D company, and 30 days in the E company, and the average lead time is 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 of these is calculated. For example, in the case of the variety "MOT-X", 25 ten thousand yen is obtained in the a factory, 25 ten thousand yen is obtained in the B factory, 20 ten thousand yen is obtained in the C company, 15 ten thousand yen is obtained in the D company, and 5 ten thousand yen is obtained in the E company, and the average cost thereof becomes 18 ten thousand yen.

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

In the case where the item 1341 is a lead period, 10 stages are distinguished in the range of the maximum value thereof from the minimum value 0. In the present example, the maximum value is 15, and therefore 0 or more and less than 1.5 is set to 1 point, 1.5 or more and less than 3 is set to 2 points, and 13.5 or more is set to 10 points. For example, in the case of the breed "MOT-X", the evaluation value 1344 is 15, and therefore the evaluation point 1345 is 10.

In the case where the item 1341 is a cost, 10 stages are distinguished in the range of the maximum value and the minimum value 0. In the present example, the maximum value is 22 ten thousand yen, and therefore 0 or more and less than 2.2 is set to 1 point, 2.2 or more and less than 4.4 is set to 2 points, and 19.8 or more is set to 10 points. For example, in the case of the breed "MOT-X", the evaluation value 1344 is 18 ten thousand yen, and therefore the evaluation point 1345 becomes 9 points.

The priority item order generation unit 120 assigns evaluation points to items by item, sorts the items in ascending order of the evaluation points, creates a rank 1342, and stores the rank in the storage unit 13 as priority item order information 134. As a method of converting the evaluation value into the evaluation point number, in the present embodiment, the interval is divided at intervals such as 10-stage evaluation, but the evaluation value may be converted into the evaluation point number by a method other than the above.

Next, the priority item order generation unit 120 calculates the total evaluation point number from the evaluation point numbers of the respective items. In the present embodiment, the total evaluation point number is calculated by multiplying the evaluation point numbers. For example, in the case of the item "MOT-X", the evaluation point 1345 when the item 1341 is the operation rate is 10 points, the evaluation point 1345 when the item 1341 is the lead cycle is 10 points, and the evaluation point 1345 when the item 1341 is the cost is 9 points. When the evaluation points are multiplied, 900 points are obtained as 10 points × 9 points. That is, the evaluation point 1345 of the item 1341 is 900 points in the total.

The priority item order generation unit 120 assigns a total evaluation point to each item, sorts the evaluation points in ascending order, creates a rank 1342, and stores the rank in the storage unit 13 as priority item order information 134. As a method of calculating the total evaluation point number from the evaluation point numbers of the respective items, a method of multiplying the evaluation point numbers is adopted, but the total evaluation point number may be calculated from the evaluation point numbers of the respective items by a method other than the above-described method, such as an addition method or a weight multiplication method.

At the end of step S3, the priority item ranking generating unit 120 creates priority item ranking 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", the parent-child relationship is shown by extracting the item constituted by the item information 131, as shown in fig. 11.

The analysis of fig. 11 is as follows. It is shown that the parent variety 1371 "Standard 200" is produced from the child varieties 1372 "MKG-X" and "SGY-X", and "MKG-X" is produced from the "MCH-X" and "GBN-X". Whether or not these items match the items 1343 registered as the aggregate in the item 1341 of the priority item order information 134 in ascending order of the rank 1342 is checked, and if they match, the item 1341 is registered as the case number 001 in the rank 1342 and the item 1343. For example, "MOT-X" whose overall evaluation rank is 1 is also used in the case whose case number 1301 is 001, and is therefore registered in the priority item order information 134. Next, "MOT-Y" whose overall evaluation rank is 2 bits is not used in the case whose case number 1301 is 001, and therefore is not registered in the priority item order information 134 as information corresponding to the case whose case number 1301 is 001. 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 how easily the components of each item are a factor in generating a supply chain design that does not satisfy at least one of the delivery date and the target original price. For example, when a supply chain design plan for selecting a production site is created for a component produced at a production site with a high operation rate, the production of the component is not acceptable as a result of no margin in the operation rate at the production site, and the possibility of failure to meet delivery dates or the like becomes high. In addition, when a production base or a purchase place with a long lead time is selected, the possibility that the generated supply chain design does not satisfy the delivery date becomes high. Similarly, when a production base or a purchase place with high cost is selected, the possibility that the generated supply chain design does not satisfy the target original price becomes high.

Therefore, for example, the priority item rank is determined such that the higher the operating rate of the production site is, the higher the lead cycle of the production site or the purchasing site is, and the higher the cost of the production site or the purchasing site is.

Reference is again made to fig. 10. Subsequently, the arithmetic unit 12 repeatedly executes the processing of step S4 to step S6 in the order of the priority item. The priority item sequence is an order of items 1343 obtained by sorting records in which the item 1341 of the priority item sequence information 134 matches the case number in ascending order of the order 1342.

In step S5, the supply chain plan creation unit 121 reads the item information 131, the production base information 132, and the procurement location information 133, creates the supply chain plan information 135, and stores the supply chain plan information 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 case number 001 and the item 1343 with the rank 1342 being 1 is "MOT-X", and therefore the supply chain design plan generating unit 121 initially determines the production site/purchase site of "MOT-X".

First, the supply chain design plan creating unit 121 extracts records matching the item 1343 from the item 1322 in the production site information 132 and the item 1332 in the procurement site information 133. If the product 1343 is "MOT-X", the "a plant" and the "B plant" are extracted as the plant 1321 from the production base information 132, and the "C company", "D company", and "E company" are extracted as the procurement site 1331 from the procurement site information 133. The supply chain design plan generating unit 121 evaluates whether or not the delivery date is satisfied at the time point for the supply chain design plans of the five modes, and excludes the supply chain design plan not satisfying the delivery date from the supply chain design plan at the time point.

The supply chain design plan generating unit 121 first calculates the shortest lead time when all the higher-level products of "MOT-X" (MCH-X and "MKG-X" in the example of fig. 11) are subjected to internal work, adds the lead time to the value of the higher-level products if the production base is "a factory" or "B factory", adds the lead time to the value of the higher-level products if the production base is "C factory", "D factory", or "E factory", and determines whether or not the current + lead time satisfies the delivery date.

In the above example, the shortest lead time when all the top-ranked varieties of "MOT-X" were subjected to internal work was 3 days for "MCH-X +" 1 day for "MKG-X", and the total was 4 days. The lead times of the factory a, the factory B, the company C, the company D, and the company E are 5 days, 10 days, 15 days, and 30 days, respectively, based on the production site information 132 and the purchase site information 133. Further, the delivery date is 2019/6/1 based on the case information 130. When 2019/5/1 is currently available, the purchase from company E requires 4 days +30 days to 34 days, and the completion date is 2019/5/1+34 days to 2019/6/3, which does not satisfy the delivery date. Therefore, the supply chain design plan generating unit 121 excludes company E that does not satisfy the delivery date at this point in time, and performs supply chain design of the next item of priority order based on the supply chain design plans of the remaining four patterns (i.e., company a, company B, company C, and company D).

Next, the supply chain design scenario generation unit 121 determines the production site/procurement site of the item 1343 "MCH-X" whose item 1341 in the priority item order information 134 is the case number 001 and whose rank 1342 is 2. In the case of "MCH-X", a factory a and a factory B are extracted as a factory 1321 from the production base information 132, and a company B is extracted as a place of purchase 1331 from the place of purchase information 133.

Here, in the case of purchasing "MCH-X" from company B, "MOT-X" of the sub-component is included in "MCH-X" purchased from company B (i.e., the cost thereof is also included in the purchase cost of "MCH-X" from company B), and therefore, it is not necessary to separately manufacture "MOT-X" at the company itself or separately purchase "MOT-X" from another company. Therefore, when "MCH-X" is purchased from company B, it is not necessary to select the four modes of company A, B, C, and D as the production site or the purchase site of "MOT-X".

Therefore, consider a supply chain design that combines eight modes, combining two modes of selecting "MCH-X" from A plant, B plant, C corporation, D corporation, with four modes of selecting the previous "MOT-X" from A plant, B plant, C corporation, and a mode of purchasing "MCH-X" from B corporation, totaling nine modes.

As in the case of the "MOT-X" described above, the supply chain design plan generating unit 121 evaluates whether or not the delivery date is satisfied at that point in time for the nine-mode supply chain design plans, and excludes the supply chain design plan that does not satisfy the delivery date from the supply chain design plan at that point in time. For example, in a mode in which internal work is performed on "MCH-X" at a plant and internal work is also performed on "MOT-X" at a plant, the shortest production lead time when all the higher-level items of "MCH-X" are subjected to internal work is 9 days in total, which is obtained by adding 1 day of "MKG-X" to 3 days of the production lead time at a plant of "MCH-X" and 5 days of the production lead time at a plant of "MOT-X", and when the current date is 2019/5/1, the number of days is sufficient to reach delivery date 2019/6/1. The supply chain design plan generating unit 121 performs the same calculation for the remaining eight patterns, evaluates whether or not the delivery date is satisfied at that point in time, and excludes the supply chain design plan that does not satisfy the delivery date from the supply chain design plan at that point in time.

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

As described above, the priority item order is set such that the higher the ease with which components of each item can be used to create a supply chain plan that does not satisfy at least one of the delivery date and the target original price, the higher the priority item order. Therefore, by generating the supply chain plan in the order of the priority items, in the process of repeatedly executing step S5 in the loop of steps S4 to S6, it is possible to find a supply chain plan that does not satisfy the delivery date relatively early (i.e., at a stage where the number of repetitions at the end is still small). By excluding such a supply chain design scheme from the target of processing in advance, useless calculation can be omitted, and the processing time can be shortened.

In the above example, whether or not the delivery date is satisfied is determined based on the lead period, but similarly, whether or not the target original price is satisfied may be determined based on the cost, and in the case where the target original price is not satisfied, the scenario may be excluded. In addition, both the determination of whether the delivery date is satisfied based on the lead time and the determination of whether the target original price is satisfied based on the cost may be performed. In the above example, the plan is excluded when the delivery date is not satisfied, but the plan may be excluded when the delivery date exceeds a predetermined value or more, while the plan may be allowed to exceed a certain level. The same is true with respect to cost. Alternatively, it is also possible to leave only the solution that either one of the delivery date or the target original price exceeds without excluding it. Thus, even a supply chain design not meeting the requirements such as delivery date can be left with a supply chain design having a margin for adjustment thereafter.

In the above-described embodiment, in the case of creating the combination mode of the production base or the purchasing place, the production conditions such as the production lead time and the production cost and the purchasing conditions such as the purchasing lead time and the purchasing cost are described using only one mode, but a plurality of modes may be used. In this case, the pattern is created by a combination of the basis and the condition.

After the process from step S4 to step S6 is repeated, the supply chain design plan evaluation unit 122 reads the supply chain design plan information 135, evaluates whether or not the evaluation index such as the delivery date and the original price has reached the target value, generates the supply chain design plan evaluation result information 136 as the evaluation result, and stores the same in the storage unit 13 (step S7).

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

Specifically, fig. 12 shows an example in which the lead cycle and cost of "MCH-X" are calculated for design number 1 of case number 001. The supply chain design plan evaluation unit 122 first calculates an evaluation value 1381 for each item. For example, if it is "MCH-X", the production lead time is 2 days and the production cost becomes 20 ten thousand yen when the production site is the a plant based on the supply chain design information 135.

The supply chain design plan evaluation unit 122 calculates an evaluation value for each item individually, and then determines a range 1382 of the constituent items of each item. For example, in the case of "BAC-X", the constituent strain is "ROH-A". If the "MCH-X" is used, the constituent species are "BAC-X", "ROH-A", "MOT-X", "BRK-X" and "ROH-C". After determining the ranges 1382 of the constituent varieties of the respective varieties, the evaluation values 1383 of the entire constituent varieties are calculated.

For example, in the case of "BAC-X", the purchase lead cycle of "ROH-a" is 7 days + the production lead cycle of "BAC-X" is 2 days to 9 days, and the production cost is 13 ten thousand yen by the same calculation. In addition, in the case of "MCH-X", the lead cycle of "BAC-X" as a constituent item is 9 days, "MOT-X" is 10 days, "BRK-X" is 11 days, "MCH-X" itself (i.e., the number of days from the start of production to the end of production of "MCH-X" when all the constituent items are collected) is 2 days, and therefore the overall lead cycle of "MCH-X" including the lead cycle of the constituent item becomes MAX (9 days, 10 days, 11 days) +2 days as 13 days. Since the cost is simply calculated, the cost becomes 20 ten thousand yen +13 ten thousand yen +20 ten thousand yen, which is 73 ten thousand yen.

The supply chain design evaluation unit 122 performs the same processing as described above for the constituent items other than the "MCH-X", and calculates the lead time and cost of the "specification 200" of the top item of BOM. Then, the calculation result is compared with the target value of the evaluation index, and whether or not the target value is reached is determined, whereby supply chain design plan evaluation result information 136 for each case is generated and stored in the storage unit 13.

Reference is again made to fig. 10. After the repeated processing of steps S2 to S8, the supply chain design scenario evaluation unit 122 determines whether or not the target value of the evaluation index is reached in all cases (step S9). If the supply chain design scenario evaluation unit 122 determines that the target value of the evaluation index is not reached in all cases (i.e., if the target value of the evaluation index is not reached in at least one case) (no in step S9), the process proceeds to step S10. If the supply chain design scenario evaluation unit 122 determines that the target value of the evaluation index is reached in all cases (yes in step S9), the process proceeds to step S11.

Next, the case-to-case adjustment unit 123 reads the supply chain design plan information 135 and the supply chain design plan evaluation result information 136, and generates and evaluates an adjustment plan for a case that cannot reach the target value of the evaluation index such as the delivery date and the original price by individual optimization for each case. Then, the case adjustment unit 123 adds the generated and evaluated results to the supply chain design plan information 135 and the supply chain design plan evaluation result information 136, and stores the result in the storage unit 13 (step S10).

Specifically, the inter-case adjustment unit 123 first generates a combination of supply chain design plans of cases having high degrees of commonality of the item, production base/place of purchase, and time, for cases that do not reach the target value of the evaluation index, based on the supply chain design plan information 135 and the supply chain design plan evaluation result information 136. For example, the higher the proportion of the same kind of parts among the parts included in the two cases, the higher the proportion of the parts acquired from the same production base or procurement location among the parts included in the two cases, or the closer the delivery dates of the two cases, the higher the degree of commonality.

Combination table 1391 in fig. 13 is an example of generation of a combination of supply chain design plans for highly common cases, and

design plans

1 and 2 of case number 001 and

design plans

1 and 2 of case number 002 are both supply chain design plans for cases having high common degrees of varieties, places of purchase, and times, and are both to purchase variety BAC-X from company C or company D. The four solutions are such that the delivery date meets the target value and the original price does not meet the target value. In contrast, the case adjustment unit 123 generates production, procurement, and distribution conditions that satisfy the target value of the original price.

For example, when the variety BAC-X is observed again, the delivery date is satisfied even if the purchase lead time is 15 days. In contrast, in the present situation, the purchase delivery cycle of company C is 10 days, but instead of extending the date to 15 days, whether or not the current purchase cost can be reduced by 20 ten thousand yen is attempted to deal with. Since the target original price of case number 001 exceeds 5 ten thousand yen and the target original price of case number 002 exceeds 4 ten thousand yen, the inter-case adjustment unit 123 creates a plan in which the procurement cost is 15 ten thousand yen, which is 5 ten thousand yen cheaper than the current situation, so that the target original price is satisfied for any case.

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

In the above example, a plurality of supply chain designs were made that all met the delivery date and did 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. In contrast, if the manufactured supply chain design does not satisfy the delivery date and satisfies the target original price, the inter-case adjustment unit 123 can generate an adjustment plan that allows an increase in cost instead of shortening the lead time.

In this way, when one of the plurality of requirements is satisfied and the other is not satisfied, by relaxing the condition (for example, lead time) related to the satisfied one of the requirements (for example, delivery date) and tightening the condition (for example, cost) related to the unsatisfied one of the requirements (for example, target original price), it is possible to generate an adjustment plan which satisfies all of the requirements and is easily accepted by negotiation.

In the above example, the adjustment plan is designed so that the lead time of the same component in the other supply chain design plans satisfying the delivery date (the purchase lead time of company D in the above example) is set as the upper limit so as to extend the purchase lead time of company C from 10 to 15, and thus an adjustment plan with a high possibility of being realized can be generated. Similarly, when an increase in cost is allowed for the purpose of reducing the lead time, and when there is another supply chain design that satisfies the target original price, the adjustment plan can be generated by setting the value of the cost of the same component of the design plan as the upper limit.

In the above example, the case adjustment unit 123 generates an adjustment plan for changing the production conditions or the procurement conditions for the same type of parts produced in the same production base or purchased from the same procurement location with respect to the supply chain design plans of the plurality of cases. However, the inter-case adjustment unit 123 may generate an adjustment plan for one supply chain design plan of one case. In this case, for example, an adjustment plan that may be accepted by negotiation, such as cost reduction instead of lead time extension, can be generated as described above.

However, as described above, by generating an adjustment plan across a plurality of cases, particularly when cost reduction is achieved, it is considered that the possibility of being accepted by mass production effects increases. In addition, the ordering party can propose an adjustment scheme that can collectively eliminate the same problems concerning the delivery date and the target original price for a plurality of cases having a high degree of commonality, thereby reducing the burden of processing.

Reference is again made to fig. 10. Finally, the supply chain design plan display unit 140 generates a supply chain design result screen based on the case information 130, the supply chain design plan information 135, and the supply chain design plan evaluation result information 136, and transmits the screen 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 plan display area 1413, a design plan number selection button 1414, a specification information scroll bar 1415, and an inter-case adjustment information table 1416.

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

Then, the type, quantity, production base/purchase location, production/purchase lead time, production/purchase cost, and negotiation flag associated with the selected design number are acquired from the supply chain design information 135, and displayed in the specification information field 14131. Then, information indicating whether or not the evaluation index such as the delivery date and the original price relating to the selected design number has reached the target value is acquired from the supply chain design evaluation result information 136, and the information is displayed in the evaluation index information field 14132. The contents displayed in the specification information field 14131 can be switched by the specification information scroll bar 1415.

Finally, when there is an engagement identification of the item related to the design number selected by design number selection button 1414, the case number, design number, item, quantity, production base/place of purchase, production/purchase lead time, and production/purchase cost having the same engagement identification number are acquired from supply chain design information 135, and these pieces of information are displayed on inter-case adjustment information table 1416. The form of 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 supply chain design plan for each case from a huge combination of a purchase place, a production place, and the like in a short time. Further, by individually optimizing each case, it is possible to create an adjustment plan for a case that cannot reach a target value of an evaluation index such as a delivery date and an original price. This can improve the delivery date compliance rate and the yield rate.

The typical example of the embodiment of the present invention described above is summarized as follows. That is, a supply chain design system according to an embodiment of the present invention (for example, the supply chain independent design system 1 of fig. 1) includes a calculation unit (for example, a calculation unit 12) and a storage unit (for example, a storage unit 13) that stores at least one of production site information (for example, production site information 132) and procurement site information (for example, procurement site information 133), case information (for example, case information 130), and item information (for example, item information 131), the case information including specifications (for example, specifications 1305) of delivered goods for each case of a pick-up order and evaluation criteria (for example, delivery date 1303, target original price 1304) of a supply chain design plan for each case, the item information including items (for example, parent item 1311 and child item 1312) of components constituting the delivered goods, and the production site information including items (for example, item 1322) and item 1304 of components produced at each production site, And production conditions (for example, a production lead time 1323, a production cost 1324, and the like), wherein the procurement-location information includes the item (for example, the item 1332) of the component purchased from each procurement location and the procurement conditions (for example, the procurement lead time 1333, the procurement cost 1334, and the like), the arithmetic unit generates one or more supply chain design plans including the production base or the procurement location of each component constituting the delivered good for each case (for example, steps S4 to S6), evaluates each supply chain design plan based on the evaluation criterion (for example, step S9), generates an adjustment plan in which the production conditions or the procurement conditions are changed for a supply chain design plan that does not satisfy the evaluation criterion (for example, step S10), and outputs the generated adjustment plan (for example, step S11).

This enables case-by-case supply chain design with improved delivery date compliance/profitability.

Here, the calculation unit may generate an adjustment plan (for example, an adjustment plan shown in fig. 13) in which the production conditions or the purchase conditions of the same type of component are changed in the same manner when the supply chain design plans of the plurality of cases each of which does not satisfy the evaluation criterion include the same type of component produced in the same production base or purchased from the same purchase place.

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

The calculation unit may calculate the degree of commonality on the basis of at least one of the type of the parts included in the delivered goods, the production base or the place of purchase of the parts, and the delivery date of the delivered goods.

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

Further, the calculation unit may generate the supply chain design plan by determining a priority ranking (for example, ranking 1342) for each of the types of parts constituting the delivered item based on the case information, the type information, the production base information, and the purchasing place information, such that the calculation unit determines the production base or the purchasing place of each type of part in accordance with the priority ranking as the type is more likely to be the main cause of generation of the supply chain failure plan that does not satisfy the evaluation criterion.

In this case, the production site information may include the part type (for example, the part type 1322) produced at each production site, the production lead time, the production cost, and the operation rate (for example, the production lead time 1323, the production cost 1324, and the average operation rate 1325) for each part type, the procurement site information may include the part type (for example, the part type 1332) purchased from each procurement site, and the procurement lead time and the procurement cost (for example, the procurement lead time 1333 and the procurement cost 1334) for each part type, and the calculation unit may determine the priority (for example, the priority 1342) such that the higher the production lead time or the procurement lead time of the part is, the higher the production cost or the procurement cost of the part is, and the higher the operation rate of the plant for producing the part is.

Thus, a supply chain design that does not satisfy the required conditions (i.e., that has a low possibility of being adopted) is excluded from the objects of processing in advance, and therefore, execution of useless processing is avoided, and the overall processing time is shortened.

The evaluation criterion of the supply chain design plan for each case may include a delivery date of the delivered goods (for example, delivery date 1303) and a target original price (for example, target original price 1304), the production condition may include a production lead time and a production cost for each item of the component, the procurement condition may include a procurement lead time and a procurement cost for each item of the component, and the calculation unit may determine that the evaluation criterion is not satisfied when the supply chain design plan does not satisfy at least one of the delivery date of the delivered goods and the target original price based on the production condition of the production base and the procurement condition of the procurement location included in the supply chain design plan (for example, step S9).

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

In this case, the calculation unit may generate an adjustment plan (for example, fig. 13) for increasing the production lead time or the purchase lead time and reducing the production cost or the purchase cost when the supply chain design plan not satisfying the evaluation criterion satisfies the delivery date and does not satisfy the target original price, and may generate an adjustment plan for decreasing the production lead time or the purchase lead time and increasing the production cost or the purchase cost when the supply chain design plan not satisfying the evaluation criterion does not satisfy the delivery date and satisfies the target original price.

In this case, the calculation unit may generate a plurality of the supply chain designs for each case, and when an adjustment plan is generated to extend the production lead time or the purchase lead time and reduce the production cost or the purchase cost for any one of the parts, the calculation unit may extend the production lead time or the purchase lead time by setting a maximum value of the production lead time or the purchase lead time of the part included in the supply chain design satisfying the delivery date among the plurality of supply chain designs as an upper limit (for example, fig. 13), and when an adjustment plan is generated to increase the production cost or the purchase cost by shortening the production lead time or the purchase lead time and increase the production cost or the purchase cost for any one of the parts, the calculation unit may increase the production cost or the purchase cost by setting a maximum value of the production cost or the purchase cost of the part included in the supply chain design satisfying the target original price among the plurality of supply chain designs as an upper limit.

This enables a highly possible adjustment scheme to be generated.

the case information includes specifications of deliveries of each case of the order and evaluation criteria of a supply chain design scheme of each case,

the item information includes items of parts constituting the delivered goods,

the production site information includes the kinds of parts produced at each production site and production conditions,

the procurement site information includes the variety of parts procured from each procurement site and procurement conditions,

the arithmetic unit generates one or more supply chain design plans including a production base or a purchase location of each component constituting the delivered item for each case,

evaluating each of the supply chain designs based on the evaluation criteria,

generating an adjustment plan in which the production condition or the procurement condition is changed so as to satisfy the evaluation criterion, with respect to a supply chain design plan that does not satisfy the evaluation criterion,

outputting the generated adjustment scheme.

2. The supply chain design system of claim 1,

the calculation unit generates an adjustment plan in which the production conditions or the procurement conditions of the components of the same type are changed in the same manner when the supply chain design plans of the plurality of cases, each of which does not satisfy the evaluation criterion, include components of the same type produced in the same production base or purchased from the same procurement location.

3. The supply chain design system of claim 2,

the calculation unit generates an adjustment plan in which the production condition or the procurement condition is changed in the same manner for a supply chain design plan of a plurality of cases that are related to a plurality of cases having a high degree of commonality and do not satisfy the evaluation criterion, respectively.

4. The supply chain design system of claim 3,

the calculation unit calculates the degree of commonality on the basis of at least one of a type of a component included in the delivered goods, a production base or a place of purchase of the component, and a delivery date of the delivered goods.

5. The supply chain design system of claim 1,

the calculation unit determines, based on the case information, the item information, the production base information, and the procurement location information, a priority ranking for the item of the component constituting the delivered item, the higher the priority ranking is, the more likely the item is to become a factor in generating the supply chain design plan that does not satisfy the evaluation criterion,

the calculation unit determines a production base or a procurement location of each of the parts according to the priority order, thereby generating the supply chain plan.

6. The supply chain design system of claim 5,

the manufacturing site information includes the types of parts manufactured at the manufacturing sites and the lead time, manufacturing cost, and operating rate of each type of the parts,

the procurement location information includes the variety of the parts procured from the respective procurement locations and the procurement lead time and procurement cost for each variety of the parts,

the calculation unit determines the priority such that the higher the production lead time or the purchase lead time of the component is, the higher the production cost or the purchase cost of the component is, and the higher the operation rate of a plant that produces the component is.

7. The supply chain design system of claim 1,

the evaluation criteria of the supply chain design scheme of each case includes the delivery date and the target original price of the delivered goods,

the production conditions include a production lead time and a production cost for each variety of the component,

the procurement conditions include a procurement lead time and a procurement cost for each variety of the component,

the calculation unit determines that the evaluation criterion is not satisfied when the supply chain design plan does not satisfy at least one of the delivery date and the target original price of the delivered goods, based on the production condition of the production base and the procurement condition of the procurement location included in the supply chain design plan.

8. The supply chain design system of claim 7,

the calculation unit generates an adjustment plan for reducing the production cost or the procurement cost by extending the production lead time or the procurement lead time when the supply chain design plan not satisfying the evaluation criterion satisfies the delivery date and does not satisfy the target original price,

and generating an adjustment scheme for shortening the production lead time or the purchase lead time and increasing the production cost or the purchase cost when the supply chain design scheme which does not satisfy the evaluation criterion does not satisfy the delivery date and satisfies the target original price.

9. The supply chain design system of claim 8,

the arithmetic unit generates a plurality of the supply chain design plans for each case,

when an adjustment plan is created for extending the production lead time or the procurement lead time to reduce the production cost or the procurement cost for any one of the parts, the maximum value of the production lead time or the procurement lead time of the part included in a supply chain design plan satisfying the delivery date among the plurality of supply chain designs is set as an upper limit to extend the production lead time or the procurement lead time,

when an adjustment plan is created for shortening the production lead time or the procurement lead time and increasing the production cost or the procurement cost for any one of the parts, the maximum value of the production cost or the procurement cost for the part included in the supply chain design plan that satisfies the target original price among the plurality of supply chain designs is set as an upper limit and the production cost or the procurement cost is increased.

10. A supply chain design method executed by a supply chain design system having a calculation unit and a storage unit,

the item information includes items of parts constituting the delivered goods,

the arithmetic unit includes the steps of:

the calculation unit generates one or more supply chain design plans including a production base or a purchase location of each component constituting the delivered goods, for each case;

the calculation part evaluates each supply chain design scheme based on the evaluation criterion;

the calculation unit generates an adjustment plan in which at least one of the production condition and the procurement condition is changed so as to satisfy the evaluation criterion, for a supply chain design plan that does not satisfy the evaluation criterion; and

the calculation unit outputs the generated adjustment plan.
