Description

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

For mass-customized products that realize a uniform custom product with mass production productivity, the supplier / production area should meet the delivery date and achieve high profits according to the delivery destination, delivery date, target cost, and specifications for each project. It is desirable to design an individual supply chain that determines such factors. However, due to the huge combination of suppliers and production areas, it is difficult to design each project, and the supply chain is decided in advance. As a result, it is not possible to keep up with changes in the business environment and fluctuations in demand, leading to a decline in the on-time delivery rate and profitability. Therefore, it is effective to derive a supply chain design proposal for each project in a short time from a huge number of combinations for each project.

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

Patent Document 1 describes a technique that "when there is an order for which the delivery date is not secured, scheduling is performed in consideration of outsourced equipment" (see summary).

Patent Document 2 describes a technique of "calculating the recommendation level of a product for which purchase unit price negotiation is prioritized" (see summary).

Patent Document 3 describes a technique that "setting information necessary for generating a joint transportation route can be set visually and easily" (see abstract).

JP-A-2002-215220 JP-A-2017-49795 JP-A-2017-84085

The technique described in Patent Document 1 has a function of deriving a plan for considering outsourced processing when an evaluation index such as a delivery date is not reached due to in-house production. However, since the item is simply requested to be processed by another company, it is necessary to separately decide where to produce or procure the constituent items such as materials and parts of the item. In other words, even if the item is processed by another company, the bill of materials (BOM) does not change. In the manufacturing industry, in addition to the case where the item is outsourced, it may be purchased from another company. When purchasing from another company, the materials and parts of the item are also produced and procured by the other company, so there is no need to consider the supply chain of the materials and parts of the item. In that case, the materials and parts of the item will be excluded from the BOM. Patent Document 1 does not cover such a form. In addition, it is considered difficult to derive in a short time because all combinations will be performed when considering switching between in-house and external production.

Further, the technique described in Patent Document 2 has a function of evaluating the room for negotiation of the purchase price of the item from the past order history information, but the adjustment across a plurality of cases results in a low price and a short delivery time. You cannot create transaction terms to purchase.

Further, in the technique described in Patent Document 3, it is possible to generate a joint transportation route and evaluate the evaluation index value for the joint transportation condition input by the user, but the joint transportation condition itself is automatically generated. Can't be done.

Therefore, an object of the present invention is to derive a supply chain design proposal for each project in a short time from a huge number of combinations. Then, production / procurement / delivery conditions that can achieve the target values are generated for the projects in which the evaluation index values such as the delivery date and the cost do not reach the target values in the individual project design.

In order to solve at least one of the above problems, the supply chain design system according to the present invention has a calculation unit and a storage unit, and the storage unit includes case information, item information, production base information, and The item information includes at least one of the supplier information, the item information includes the specifications of the deliverable for each ordered item, and the evaluation criteria of the supply chain design proposal for each item. The production base information includes the items of the parts produced at each production base and the production conditions, including the items of the parts constituting the delivery, and the supplier information is the parts procured from each supplier. The calculation unit generates one or more supply chain design proposals including the production base or the procurement source of each part constituting the delivery for each of the above-mentioned items and the procurement conditions. The supply chain design proposal is evaluated based on the evaluation criteria, and for the supply chain design proposal that does not meet the evaluation criteria, an adjustment proposal in which the production conditions or the procurement conditions are changed so as to satisfy the evaluation criteria is generated and generated. It is characterized in that the above-mentioned adjustment plan is output.

According to one aspect of the present invention, it is possible to derive a supply chain design proposal for each case that improves the on-time delivery rate and the rate of return.

Examples will be described below, 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 this embodiment, the supply chain design for each project of the target article is automatically generated. Target articles include, for example, elevator devices such as elevators and escalator, electrical products, mechanical products, automobiles, trains, aircraft, generators, control devices, control panels, storage devices, network storage such as NAS (Network Attached Storage), etc. Examples include servers and water treatment equipment.

FIG. 1 is a diagram showing an example of a functional block of the supply chain individual design system 1 of this embodiment.

The supply chain individual design system 1 includes a user terminal 2, a database 3, and a supply chain individual design device 10, each of which is communicably connected via a 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 individual design device 10. The database 3 is, for example, a system such as ERP (Enterprise Resource Planning), or a database or storage device that stores data equivalent thereto.

The network CN communicateably connects the user terminal 2, the database 3, and the supply chain individual design device 10. The network CN is either a communication network that uses a part or all of a general public line such as a LAN (Local Area Network), a WAN (Wide Area Network), a VPN (Virtual Private Network), or the Internet.

The supply chain individual design device 10 is an information processing device such as a PC or a server computer. The supply chain individual 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 input of information to the supply chain individual design device 10 via an input device such as a keyboard or a touch panel. The calculation unit 12 derives a supply chain design proposal 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 or receives information with another device connected via the network CN.

The input unit 11 includes a matter information input unit 110, an item information input unit 111, a production base information input unit 112, and a supplier information input unit 113.

The matter information input unit 110, the item information input unit 111, the production base information input unit 112, and the supplier information input unit 113 each acquire necessary information from the user terminal 2 or the database 3 via the communication unit 15. , The acquired information is stored in the storage unit 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-project coordination unit 123.

The priority item order generation unit 120 generates a priority item order when designing the supply chain. In supply chain design, as mentioned above, if you switch the item to external production (that is, procurement by purchasing from another company) instead of in-house production (that is, production at your own production base), consider the lower level items. It becomes unnecessary. Therefore, it is common to consider from the highest level item of BOM.

However, for example, there may be a rework such as giving up the in-house production of the lower-level item because the delivery date cannot be met depending on the production or procurement status, and reconsidering the production base change or the external production of the upper-level item. Therefore, in order to prevent rework, it is desirable to generate a priority item order from the load status of the production base and the transaction conditions of the supplier, and consider the supply chain design in the order of priority items. There is a priority item order generation unit 120 in order to reduce rework when performing such a supply chain design.

The priority item order generation unit 120 calculates each evaluation index for each item, generates a priority item order by integrating the evaluation indexes, and compares the matter specifications with the overall result of the priority item order for each matter. Generate a priority item order for. The priority item order generation 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 that determine the production base / production conditions and the procurement source / procurement conditions for each item according to the priority item order for each project. 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 cost 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-project coordination unit 123 confirms the supply chain design proposal evaluation results of each project, extracts the projects whose evaluation index values such as delivery date and cost do not reach the target values, and produces and procures that meets the target values of the evaluation indexes. -Generate shipping conditions. At that time, the inter-project coordination unit 123 not only generates production / procurement / delivery conditions that satisfy the target value of the evaluation index for each project, but also considers bundling a plurality of projects.

For example, if there are multiple projects that procure the same item, the price will be reduced by conducting centralized purchasing such as arranging the suppliers. In addition, if there are multiple delivery projects to the same period / area, the price will be reduced by performing joint delivery such as aligning the delivery dates. If there are multiple projects that produce the same item in-house, the price will be reduced by performing collective production such as aligning the production areas.

In this way, by making adjustments such as centralized purchasing, joint delivery, and bulk production across projects (that is, between multiple projects), we explore the possibility of achieving short delivery times and low prices, and target values for evaluation indicators. Generate a supply chain design proposal that meets the requirements. The inter-project coordination 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 includes project information 130, item information 131, production base information 132, supplier information 133, priority item order information 134, supply chain design proposal information 135, and supply chain design proposal evaluation result information 136. I remember.

The case information 130 is information about a case that the company has received an order from a customer.

Item information 131 is BOM information required when manufacturing the target article.

The production base information 132 is information related to the company's manufacturing.

The supplier information 133 is information (procurement lead time, purchase cost, etc.) regarding procurement between the supplier and the company. Procurement supplier information 133 is set at the time of processing start, with the past transaction record and consent with the supplier.

The priority item order information 134 is the priority item order information in each evaluation index and the total result of each evaluation index, and the priority item order information for each matter for each item.

Supply chain design proposal information 135 is supply chain design proposal information for each project. Supply chain design information is whether the production base / production conditions, supplier / procurement conditions, and production conditions / procurement conditions of each item that make up the specifications are different from the transaction results and master values so far and require new negotiations. Consists of flag information representing. In addition, multiple supply chain design proposals are stored for each project.

The supply chain design proposal evaluation result information 136 is the result information of evaluating whether or not the supply chain design proposal for each project has achieved the target values of the evaluation indexes such as the delivery date and the cost.

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 project stored in the matter information 130, the supply chain design proposal information 135, and the supply chain design proposal evaluation result information 136. It is transmitted to the user terminal 2 via the communication unit 15. This information is displayed on the user terminal 2. On the evaluation result screen, the supply chain design proposal that determines the production base / production conditions, supplier / procurement conditions for each item, and the target values of evaluation index values such as delivery date and cost at that time are achieved. Information indicating whether or not it has been done is displayed.

In the present embodiment, the user terminal 2 and the database 3 are provided outside the supply chain individual design device 10, but the configuration of the supply chain individual 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 individual design system 1 can be appropriately changed as long as the object of the present embodiment is not impaired.

The production base information 132 includes a factory 1321, an item 1322, a production lead time 1323 indicating the period from the start of production to the completion of production, and a production cost 1324 including assembly costs, processing costs, and production management costs related to production. Includes an average operating rate of 1325, which represents the average operating rate of processing equipment and assembly lines. In this embodiment, the unit of the production lead time 1323 will be described as a day. Further, the unit of the production cost 1324 will be described as 10,000 yen.

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

The supplier information 133 includes the supplier 1331, the item 1332, the procurement lead time 1333 indicating the period from ordering to warehousing, the procurement cost 1334 including the purchase price of the item and various expenses related to procurement, and the transaction record. Includes transaction record 1335 indicating the presence or absence. In the transaction record 1335, if there is a transaction record, the last transaction date is described. On the other hand, if there is no transaction record, but the master is set in advance with the supplier, "-" is described. In this embodiment, the unit of the procurement lead time 1333 will be described as a day. Further, the unit of the procurement cost 1334 will be described as 10,000 yen.

In this embodiment, the supply chain individual design device 10 holds both the production base information 132 and the supplier information 133, but the supply is supplied, for example, when all the parts are produced in-house. The chain individual design device 10 may not have the supplier information 133. Further, the supply chain individual design apparatus 10 may not have the production base information 132, for example, when the company does not have a production base such as a factory and procures all the parts from another company.

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

The priority item order information 134 includes item 1341, rank 1342, item 1343, evaluation value 1344, and evaluation point 1345. There are three types of values registered in item 1341: items that are important when determining the order of priority items, overall results, and each item.

In this embodiment, the operating rates of processing equipment and assembly lines, lead times related to production and procurement, and costs related to production and procurement are used as important items. The priority item order may be determined by items other than these. In addition, as a comprehensive result, in this embodiment, a comprehensive result is created from the three indicators of operating rate, lead time, and cost, and item 1341 is registered as a comprehensive result.

Further, as each matter, the matter number is registered in the item 1341, and the priority item order information for each matter is registered. Here, when the item 1341 is the total result, the evaluation value 1344 cannot be calculated, so “−” indicating a blank is described. In addition, when item 1341 is for each case, the evaluation value 1344 cannot be calculated in the same way as the total result, so a “-” indicating a blank is described, and the value of the evaluation point 1345 is the same value as the total result, which means omission. "-" Is described.

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

Supply chain design proposal information 135 includes project number 1351, design proposal number 1352, item 1353, production base / procurement destination 1354, production / procurement lead time 1355, production / procurement cost 1356, and negotiation flag 1357. including.

The negotiation flag 1357 is a flag indicating whether negotiation with the supplier is necessary. For example, when the information is created from the production base information 132 and the supplier information 133, negotiation is not necessary because an agreement has been reached with the supplier. Therefore, the negotiation flag 1357 is described with "-" indicating that negotiation is unnecessary. On the other hand, in the case of the supply chain design proposal created by the inter-project coordination department 123, the production / procurement lead time 1355 and the production / procurement cost 1356, which are the production and procurement conditions, are negotiated because the agreement has not been formed with the supplier. Is required. Therefore, a negotiation flag 1357 “N” and a number (eg, “001”) are added to indicate to the user that negotiation is necessary. This number is for identifying related matters.

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

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

FIG. 9 is a diagram showing a hardware configuration example of the supply chain individual design device 10 of this embodiment.

The supply chain individual design device 10 includes an input device 161, an output device 162, an external storage device 163, an arithmetic unit 164, a main storage device 165, and a communication device 166, and each component is provided by a bus 167. It is connected.

The input device 161 is a device that receives an input operation from the 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 individual 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 a writable and readable storage medium such as an HDD (Hard Disk Drive). The arithmetic unit 164 is a central processing unit and executes processing according to a program recorded in the main storage device 165 or the external storage device 163. The functions of the processing units constituting the arithmetic unit 12 are realized by the arithmetic unit 164 executing the 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 individual 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. Further, the storage unit 13 may have its function realized by a storage device on the network CN, or may have its function realized by the database 3 as described above.

The processing of each component of the supply chain individual design device 10 may be executed by one hardware or may be executed by a plurality of hardware. Further, the processing of each component of the supply chain individual design device 10 may be realized by one program or may be realized by a plurality of programs. Since the user terminal 2 and the database 3 also have the same hardware configuration as the supply chain individual design device 10, the description thereof will be omitted.

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

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

First, the matter information input unit 110, the item information input unit 111, the production base information input unit 112, and the supplier information input unit 113 read the 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 base information input unit 112 reads, for example, the production base information 132 at the time of processing from the database 3 and stores it in the storage unit 13. The procurement source information input unit 113 reads, for example, the procurement source information 133 at the time of processing from the database 3 and stores it in the storage unit 13.

Next, the calculation unit 12 repeatedly executes the processes of steps S2 to S8 for each matter. The number of items to be repeatedly executed is the number of records stored in the item number 1301 of the item information 130.

In the processing of steps S2 to S8, first, the priority item order generation unit 120 reads the matter information 130, the item information 131, the production base information 132, and the supplier information 133, and causes the priority item order information. 134 is created and stored in the storage unit 13 (step S3).

Specifically, the priority item order generation unit 120 first calculates the average operating rate, the average lead time, and the average cost for all the items included in the item information 131. The average operating rate is calculated from the average operating rate 1325 of each item obtained from the production base information 132 (FIG. 4). For example, in the case of the item "MOT-X", it is 90% at the A factory and 90% at the B factory, and the average operating rate of these is 90%.

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

The average cost is calculated from the average value of the production cost 1324 of each item obtained from the production base information 132 and the procurement cost 1334 of each item obtained from the supplier information 133. For example, in the case of the item "MOT-X", the average of these is 250,000 yen for factory A, 250,000 yen for factory B, 200,000 yen for company C, 150,000 yen for company D, and 50,000 yen for company E. The cost will be 180,000 yen.

Next, the priority item order generation unit 120 converts the evaluation value into an evaluation point for each item calculated earlier. In this embodiment, a 10-step evaluation is performed. When item 1341 is the operating rate, the maximum is 100% and the minimum is 0%, so when classified in 10 stages, 0% or more and less than 10% is 1 point, 10% or more and less than 20% is 2 points, and 90% or more. It will be 10 points. For example, in the case of the item "MOT-X", the evaluation value 1344 is 90%, so the evaluation point 1345 is 10 points.

When item 1341 is a lead time, it is divided into 10 stages within the range of the maximum value and the minimum value 0. In this embodiment, since the maximum value is 15, 0 or more and less than 1.5 is 1 point, 1.5 or more and less than 3 is 2 points, and 13.5 or more is 10 points. For example, in the case of the item "MOT-X", the evaluation value 1344 is 15, so the evaluation point 1345 is 10.

Then, when the item 1341 is a cost, it is classified in 10 stages within the range of the maximum value and the minimum value 0. In this embodiment, since the maximum value is 220,000 yen, 0 or more and less than 2.2 is 1 point, 2.2 or more and less than 4.4 is 2 points, and 19.8 or more is 10 points. For example, in the case of the item "MOT-X", the evaluation value 1344 is 180,000 yen, so the evaluation point 1345 is 9 points.

The priority item order generation unit 120 assigns evaluation points for each item, then sorts the evaluation points for each item in ascending order to create a rank 1342, and stores the priority item order information 134 in the storage unit 13. Store. As a method of converting the evaluation value into the evaluation point, in this embodiment, the interval is equalized in 10-step 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 total evaluation score from the evaluation points of each of these items. In this embodiment, the total evaluation score is calculated by multiplying each evaluation score. For example, in the case of the item "MOT-X", the evaluation point 1345 when the item 1341 is the operating rate is 10 points, the evaluation point 1345 when the item 1341 is the lead time is 10 points, and the evaluation point when the item 1341 is the cost. 1345 is 9 points. Multiplying these evaluation points gives 10 points x 10 points x 9 points = 900 points. That is, when the item 1341 is comprehensive, the evaluation point 1345 is 900 points.

The priority item order generation unit 120 assigns a comprehensive evaluation point for each item, sorts the evaluation points in ascending order, creates a rank 1342, and stores the priority item order information 134 in the storage unit 13. As a method of calculating the total evaluation score from the evaluation points of each item, the method of multiplying each evaluation point was adopted, but from the evaluation points of each item by a method other than the above, for example, a method of adding or a method of multiplying weights. The overall evaluation score may be calculated.

At the end of step S3, the priority item order generation unit 120 creates priority item order information for each matter for all the matters registered in the matter information 130. For example, when the matter number 1301 is 001 and the specification 1305 is "spec 200", an item composed of the item information 131 is extracted and the parent-child relationship is illustrated as shown in FIG.

FIG. 11 is a diagram for explaining an example of the generation process of the supply chain design proposal of this embodiment.

The view of FIG. 11 is as follows. It means that the parent item 1371 "Spec 200" is manufactured from the child items 1372 "MKG-X" and "SGY-X", and the "MKG-X" is manufactured from "MCH-X" and "GBN-X". doing. Check in ascending order of rank 1342 whether these items match item 1341 of priority item order information 134 with item 1343 registered as a whole, and if there is a match, set item 1341 as matter number 001. Register in rank 1342 and item 1343. For example, "MOT-X" having the first overall evaluation order is registered in the priority item order information 134 because it is also used in the case where the case number 1301 is 001. Next, since "MOT-Y" having the second highest overall evaluation order is not used in the case where the case number 1301 is 001, it is not registered in the priority item order information 134 as the information corresponding to the case where the case number 1301 is 001. Through such processing, priority item order information for each matter is created and stored in the storage unit 13.

The priority item order generated as described above indicates the degree to which the parts of each item are likely to generate a supply chain design proposal that does not meet at least one of the delivery date and the target cost. For example, for a part produced at a production base with a high operating rate, if a supply chain design proposal that selects the production base is generated, the production of the part is undertaken because the production base does not have a margin in the operating rate. Therefore, there is a high possibility that the delivery date will not be met. In addition, if a production base or supplier with a long lead time is selected, there is a high possibility that the generated supply chain design proposal will not meet the delivery date. Similarly, if a costly production site or supplier is selected, it is more likely that the generated supply chain design proposal will not meet the target cost.

Therefore, for example, the higher the operating rate of the production base or the supplier, the higher the rank, the longer the lead time of the production base or the supplier, the higher the rank, and the higher the cost of the production base or the supplier, the higher the rank. It is determined.

See FIG. 10 again. Next, the calculation unit 12 repeatedly executes the processes of steps S4 to S6 in the order of priority items. The priority item order is the order of the items 1343 obtained by sorting the records in which the item 1341 of the priority item order information 134 matches the matter number in the ascending order of the order 1342.

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

Specifically, for example, when the matter number 1301 is 001, the item 1341 of the priority item order information 134 is the matter number 001, and the item 1343 in which the rank 1342 is the first place is "MOT-X". The chain design proposal generation unit 121 first determines the production base / procurement source of "MOT-X".

First, the supply chain design proposal generation unit 121 extracts records that match the item 1343 from the item 1322 of the production base information 132 and the item 1332 of the supplier information 133. When the item 1343 is "MOT-X", "Factory A" and "Factory B" are extracted as the factory 1321 from the production base information 132, and "Company C" and "D" are extracted as the supplier 1331 from the supplier information 133. "Company" and "Company E" are extracted. The supply chain design proposal generation unit 121 evaluates whether or not the delivery date can be met at this point with respect to these five patterns of supply chain design proposals, and excludes those that cannot meet from the supply chain design proposals at this point.

The supply chain design proposal generation unit 121 first calculates the shortest production lead time when all the upper items of "MOT-X" ("MCH-X" and "MKG-X" in the example of FIG. 11) are produced in-house. Then, if the production base is "A factory" or "B factory", the production lead time is added to the value, and if the supplier is "C company", "D company" or "E company", the procurement lead time is added. , Present + Judge whether the lead time can meet the delivery date.

In the above example, the shortest production lead time when all the high-ranking items of "MOT-X" are produced in-house is 3 days of "MCH-X" + 1 day of "MKG-X", which is a total of 4 days. From the production base information 132 and the supplier information 133, the lead times of the A factory, the B factory, the C company, the D company, and the E company are 5 days, 5 days, 10 days, 15 days, and 30 days, respectively. In addition, the delivery date is June 1, 2019 from the case information 130. Assuming that the current time is May 1, 2019, if procured from Company E, 4 days + 30 days = 34 days, and the completion date will be 2019/5/1 + 34 days = 2019/6/3, and the delivery date cannot be met. Therefore, the supply chain design proposal generation unit 121 excludes company E, which cannot meet the delivery date, at this point, and based on the supply chain design proposals of the remaining four patterns (that is, factories A, B, C, and D). Design the supply chain for the following priority items.

Next, the supply chain design proposal generation unit 121 determines the production base / procurement source of the item 1343 “MCH-X” in which the item 1341 of the priority item order information 134 is the second item in the order 1342 of the item number 001. In the case of "MCH-X", the factories A and B are extracted as the factory 1321 from the production base information 132, and the company B is extracted as the supplier 1331 from the supplier information 133.

Here, when "MCH-X" is procured from company B, the child part "MOT-X" is included in "MCH-X" purchased from company B (that is, the cost is also included in "MCH-X" from company B. It is included in the procurement cost of "MCH-X"), so there is no need to manufacture "MOT-X" separately in-house or procure it separately from other companies. Therefore, when procuring "MCH-X" from Company B, it is necessary to select the above four patterns of Factory A, Factory B, Company C, and Company D as the production base or procurement source of "MOT-X". Is gone.

Therefore, 8 patterns that combine 2 patterns for selecting "MCH-X" from A factory and B factory and 4 patterns for selecting "MOT-X" from A factory, B factory, C company, and D company. A total of nine patterns of supply chain design proposals, including a pattern of procuring "MCH-X" from Company B, can be considered.

As in the case of "MOT-X" described above, the supply chain design proposal generation unit 121 evaluates and satisfies whether or not the delivery date can be met at this point for these nine patterns of supply chain design proposals. Those that do not exist are excluded from the supply chain design proposal at this point. For example, if "MCH-X" is produced in-house at Factory A and "MOT-X" is also produced in-house at Factory A, the shortest production lead when all the higher-level items of "MCH-X" are produced in-house. The time is the sum of 1 day of "MKG-X", 3 days of production lead time of "MCH-X" at factory A, and 5 days of production lead time of "MOT-X" at factory A. If the total is 9 days and the current time is May 1, 2019, there are enough days until the delivery date is June 1, 2019. The supply chain design proposal generation unit 121 performs the same calculation for the remaining eight patterns, evaluates whether or not the delivery date can be met at this point, and excludes those that cannot meet from the supply chain design proposal at this point.

The supply chain design proposal generation unit 121 repeats the above processing up to the item in which the item 1341 of the priority item order information 134 has the lowest rank 1342 of the matter number 001, so that the supply chain design proposal information for each matter 135 is generated and stored in the storage unit 13.

As described above, the priority item order is set so that the parts of each item are so high that they are likely to generate a supply chain design proposal that does not meet at least one of the delivery date and the target cost. Therefore, by generating the supply chain design proposal according to the order of priority items, while step S5 is repeatedly executed in the loop of steps S4 to S6, it is relatively early (that is, at a stage where the number of completed repetitions is still small). ), You can discover supply chain design proposals that do not meet the delivery date. By excluding such a supply chain design proposal from the processing target at an early stage, unnecessary calculations can be omitted and the processing time can be shortened.

In the above example, it is determined whether the delivery date is satisfied based on the lead time, but similarly, it is determined whether the target cost is satisfied based on the cost, and if it is not satisfied, the proposal can be excluded. Good. Further, it may be determined whether the delivery date based on the lead time is satisfied and whether the target cost based on the cost is satisfied. Further, in the above example, the proposal is excluded when the delivery date is not satisfied, but the proposal may be excluded when the excess delivery date exceeds a predetermined value by allowing a certain amount of excess. The same applies to the cost. Alternatively, those in which only one of the delivery date and the target cost is exceeded may be left without excluding. As a result, even if the supply chain design proposal does not meet the requirements such as delivery date, it is possible to leave a room for later adjustment.

In the above embodiment, when creating a combination pattern of a production base or a procurement source, a production condition such as a production lead time and a production cost and a procurement condition such as a procurement lead time and a procurement cost are described using only one pattern. However, there may be a plurality of patterns. In that case, a pattern is created by combining the base and the conditions.

After the iterative processing of steps S4 to S6, the supply chain design proposal evaluation unit 122 reads the supply chain design proposal information 135, evaluates whether or not the evaluation indexes such as delivery date and cost have reached the target values, and evaluates whether or not the evaluation indexes such as delivery date and cost have been achieved. The supply chain design proposal evaluation result information 136, which is the evaluation result, is generated and stored in the storage unit 13 (step S7).

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

FIG. 12 is a diagram for explaining an example of the evaluation process of the supply chain design proposal of this 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 the evaluation value 1381 for each item individually. For example, in the case of "MCH-X", from 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 evaluation value of each item individually. For example, in the case of "BAC-X", the constituent item is "ROH-A". If it is "MCH-X", the constituent items are "BAC-X", "ROH-A", "MOT-X", "BRK-X" and "ROH-C". After defining the range 1382 of the constituent items of each item, the evaluation value 1383 for all of these constituent items 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 130,000 yen by the same calculation. become. In the case of "MCH-X", the lead time of the component "BAC-X" is 9 days, the procurement lead time of "MOT-X" is 10 days, and the lead time of "BRK-X" is 11 days. Therefore, the production lead time of the "MCH-X" itself (that is, the number of days from the start to the end of the production of the "MCH-X" with all the components) is 2 days, so that the lead of the components The lead time of the entire "MCH-X" including the time is MAX (9th, 10th, 11th) + 2nd = 13th. Since the costs are simply added up, the costs are 200,000 yen + 130,000 yen + 200,000 yen + 200,000 yen = 730,000 yen.

The supply chain design proposal evaluation unit 122 performs the same processing as above for the constituent items other than the “MCH-X”, and calculates the lead time and cost of the “spec 200” of the BOM top item. Then, by comparing the calculation result with the target value of the evaluation index and determining whether or not the achievement has been achieved, the supply chain design proposal evaluation result information 136 for each case is generated and stored in the storage unit 13.

See FIG. 10 again. After the iterative 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 achieved in all the projects (step S9). When the supply chain design proposal evaluation unit 122 determines that the target value of the evaluation index is not achieved in all the projects (that is, the target value of the evaluation index is not achieved in at least one project) (when “NO” in step S9). , 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 achieved in all the projects (when “YES” in step S9), the process proceeds to step S11.

Next, the inter-project coordination unit 123 reads the supply chain design proposal information 135 and the supply chain design proposal evaluation result information 136, and achieves the target values of the evaluation indexes such as delivery date and cost by individual optimization for each project. Generate and evaluate adjustment proposals for projects that could not be done. Then, the inter-case coordination unit 123 adds the result of generation and evaluation to the supply chain design proposal information 135 and the supply chain design proposal evaluation result information 136, and stores the result in the storage unit 13 (step S10).

Specifically, the inter-project coordination unit 123 first obtains items, production bases / procurement for projects for which the target value of the evaluation index has not been reached, based on the supply chain design proposal information 135 and the supply chain design proposal evaluation result information 136. Generate a combination of supply chain design proposals for projects that have a high degree of commonality in terms of destination and timing. For example, the higher the proportion of parts of the same item among the parts included in the two projects, the higher the proportion of parts acquired from the same production base or supplier among the parts included in the two projects, or The closer the delivery dates of the two projects are, the higher the commonality.

FIG. 13 is a diagram for explaining an example of the inter-project adjustment process of this embodiment.

The combination table 1391 of FIG. 13 is an example of generating a combination of supply chain design proposals of projects having a high degree of commonality, and which of the design proposal numbers 1 and 2 of project number 001 and the design proposal numbers 1 and 2 of project number 002 is generated. Is also trying to procure item BAC-X from company C or company D, and is a supply chain design proposal for a project with a high degree of commonality in item, supplier, and timing. The delivery date of all four plans meets the target value, but the cost does not meet the target value. Therefore, the inter-project coordination unit 123 generates production / procurement / delivery conditions so as to satisfy the target value of cost.

For example, looking at item BAC-X again, even if the procurement lead time is 15 days, the delivery date is satisfied. Therefore, at present, the procurement lead time of Company C is 10 days, but instead of extending it to 15 days, we will try to negotiate whether the current procurement cost of 200,000 yen can be reduced. Since the project number 001 exceeds the target cost by 50,000 yen and the project number 002 exceeds the target cost by 40,000 yen, the inter-project coordination department 123 has a procurement cost higher than the current value so that the target cost is satisfied in any project. Generate a plan to make it 150,000 yen, which is 10,000 yen cheaper.

The supply chain design proposal evaluation unit 122 again evaluates the supply chain design proposal 1392 created by the inter-project coordination unit 123. Then, the created new supply chain design proposal and 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 are stored in the storage unit 13.

In the above example, all of the created supply chain design proposals meet the delivery date and do not meet the target cost. For this reason, the inter-project coordination unit 123 has generated an adjustment plan that reduces costs instead of extending the lead time. On the other hand, if the created supply chain design proposal does not meet the delivery date and meets the target cost, the inter-project coordination unit 123 proposes an adjustment proposal that allows an increase in cost instead of shortening the lead time. Can be generated.

In this way, when one of the plurality of requirements is satisfied and the other is not satisfied, the conditions (for example, lead time) related to the requested one (for example, delivery date) are relaxed and satisfied. By tightening the conditions (eg cost) related to the unfulfilled requirements (eg target cost), it is possible to generate an adjustment proposal that meets all the requirements and is easily accepted by negotiation.

In addition, as in the case where the procurement lead time of company C is extended from 10 days to 15 days in the above example, the lead time of the same parts in other supply chain design proposals that meet the delivery date (in the above example, company D). By designing the adjustment plan with the procurement lead time) as the upper limit, it is possible to generate an adjustment plan that is highly likely to be realized. The same applies when allowing an increase in cost to reduce lead time, and if there is another supply chain design proposal that meets the target cost, the cost value of the same part of that design proposal is the upper limit. Adjustment proposals can be generated.

In the above example, the inter-project coordination unit 123 refers to parts of the same item that are produced at the same production base or procured from the same supplier for the supply chain design proposals of a plurality of projects. , Generate adjustment proposals to change production conditions or procurement conditions. However, the inter-project coordination unit 123 may generate coordination proposals for one supply chain design proposal for one project. In that case as well, adjustment proposals that may be accepted by negotiation can be generated, for example, by lowering the cost instead of extending the lead time as described above.

However, as described above, it is considered that the possibility of being accepted by the mass production effect is increased by generating the adjustment plan across a plurality of projects, especially when the cost is reduced. In addition, the ordering party can also propose an adjustment plan that can collectively solve the same problem regarding the delivery date or the target cost for a plurality of projects having a high degree of commonality, and the processing burden is reduced.

See FIG. 10 again. Finally, the supply chain design proposal display unit 140 generates a supply chain design result screen from the matter information 130, the supply chain design proposal information 135, and the supply chain design proposal evaluation result information 136, and transmits the supply chain design result screen to the user terminal 2. (Step S11). After that, the calculation 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 this embodiment.

The supply chain design result screen 141 includes a matter number selection button 1411, a matter 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-project adjustment information table. 1416 and.

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

Then, the item, quantity, production base / procurement source, production / procurement lead time, production / procurement cost, and negotiation flag related to the selected design proposal number are acquired from the supply chain design proposal information 135. , Displayed in the specification information column 14131. Then, information indicating whether or not the evaluation index such as the delivery date and cost related to the selected design proposal number has achieved the target value is acquired from the supply chain design proposal evaluation result information 136 and displayed in the evaluation index information column 14132. Will be done. The specification information scroll bar 1415 can be used to switch the content displayed in the specification information field 14131.

Finally, if there is a negotiation flag for the item related to the design proposal number selected by the design proposal number selection button 1414, the matter number, the design proposal number, the item, the quantity, and the production having the same negotiation flag number. The base / procurement source, production / procurement lead time, and production / procurement cost are acquired from the supply chain design proposal information 135 and displayed in the inter-project adjustment information table 1416. In addition, the format showing the supply chain design result is not limited to the mode shown in FIG.

According to this embodiment, it is possible to derive a supply chain design proposal for each project in a short time from a huge number of combinations of suppliers, production areas, and the like. In addition, by individual optimization for each project, it is possible to generate adjustment proposals for projects that could not achieve the target values of evaluation indexes such as delivery date and cost. This is expected to improve the on-time delivery rate and profitability.

A typical example of the embodiment of the present invention described above can be summarized as follows. That is, the supply chain design system of one aspect of the present invention (for example, the supply chain individual design system 1 of FIG. 1) has a calculation unit (for example, calculation unit 12) and a storage unit (for example, storage unit 13). The storage unit includes at least one of case information (for example, case information 130), item information (for example, item information 131), production base information (for example, production base information 132), and supplier information (for example, supplier information 133). The item information includes the specifications of the deliverable for each ordered item (for example, specification 1305) and the evaluation criteria for the supply chain design proposal for each item (for example, delivery date 1303 and target cost 1304). The information includes the items of the parts constituting the delivery (for example, the parent item 1311 and the child item 1312), and the production base information includes the items of the parts produced at each production base (for example, item 1322) and the production conditions (for example, item 1322). The supplier information includes the production lead time 1323 and the production cost 1324, etc.), and the supplier information includes the item of the parts procured from each supplier (for example, item 1332) and the procurement conditions (for example, the procurement lead time 1333 and the procurement cost 1334, etc.). ), And, for each case, the calculation unit generates one or more supply chain design proposals including the production base or supplier of each part constituting the delivery (for example, steps S4 to S6), and each supply chain. The design proposal is evaluated based on the evaluation criteria (for example, step S9), and for the supply chain design proposal that does not meet the evaluation criteria, an adjustment proposal in which the production conditions or procurement conditions are changed so as to meet the price criteria is generated (for example, step S10). ), The generated adjustment plan is output (for example, step S11).

As a result, it is possible to derive a supply chain design proposal for each project that improves the on-time delivery rate and the rate of return.

Here, the calculation unit selects parts of the same item in which supply chain design proposals for a plurality of projects, each of which does not meet the evaluation criteria, are produced at the same production base or procured from the same supplier. When including, an adjustment plan (for example, an adjustment plan shown in FIG. 13) in which the same change is made to the production conditions or procurement conditions of parts of the same item may be generated.

At this time, the calculation unit generates an adjustment plan in which the same changes are made to the production conditions or procurement conditions for the supply chain design proposals of a plurality of projects, each of which does not meet the evaluation criteria, for a plurality of projects having a high degree of commonality. You may.

Further, the calculation unit may calculate the commonality based on at least one of the item of the part included in the delivery, the production base or the supplier of the part, and the delivery date of the delivery.

As a result, it is possible to generate an adjustment plan that is easy for the supplier to accept and negotiate because of the mass production effect.

In addition, the calculation department is likely to be a factor in generating supply chain design proposals that do not meet the evaluation criteria for the items of the parts that make up the delivery, based on the project information, item information, production base information, and supplier information. The supply chain design proposal may be generated by determining the priority (for example, order 1342) so that the higher the number is, and determining the production base or the supplier of the parts of each item according to the priority.

At this time, the production base information includes the item of the part produced at each production base (for example, item 1322), the production lead time, the production cost and the operating rate (for example, the production lead time 1323, the production cost 1324) for each item of the part. The supplier information includes the average operating rate of 1325), the item of the part procured from each supplier (for example, item 1332), and the procurement lead time and the procurement cost for each item of the part (for example, the procurement lead time 1333 and). Including the procurement cost 1334), the calculation unit is ranked higher as the production lead time or procurement lead time of the part is longer, and higher as the production cost or procurement cost of the part is higher, and the operation of the factory that produces the part is performed. The priority (for example, rank 1342) may be determined so that the higher the rate, the higher the rank.

As a result, supply chain design proposals that do not meet the required conditions (that is, are unlikely to be adopted) are excluded from the processing target at an early stage, so unnecessary processing execution is avoided and the overall processing time is shortened. Will be done.

In addition, the evaluation criteria of the supply chain design proposal for each project include the delivery date (for example, delivery date 1303) and the target cost (for example, target cost 1304) of the delivery, and the production conditions are the production lead time and production cost for each item of the parts. The procurement conditions include the procurement lead time and procurement cost for each item of the part, and the calculation unit is based on the production conditions of the production base and the procurement conditions of the supplier included in the supply chain design proposal. If the design proposal does not meet at least one of the delivery date and the target cost of the delivery, it may be determined that the evaluation criteria are not met (for example, step S9).

As a result, the quality of the generated supply chain design proposal is appropriately judged.

At this time, if the supply chain design proposal that does not meet the evaluation criteria meets the delivery date and does not meet the target cost, the calculation unit will extend the production lead time or procurement lead time and reduce the production cost or procurement cost. (For example, FIG. 13), when a supply chain design proposal that does not meet the evaluation criteria meets the target cost without meeting the delivery date, the production lead time or procurement lead time is shortened to increase the production cost or procurement cost. Adjustment proposals may be generated.

Further, at this time, the calculation unit generates a plurality of the supply chain design proposals for each case, extends the production lead time or the procurement lead time for the item of any part, and reduces the production cost or the procurement cost. When generating an adjustment plan, the production lead time or the production lead time or the maximum value of the procurement lead time of the item of the relevant part included in the supply chain design plan that satisfies the delivery date is set as the upper limit among the plurality of supply chain design plans. When the procurement lead time is extended (for example, FIG. 13) to generate an adjustment plan for shortening the production lead time or the procurement lead time to increase the production cost or the procurement cost for the item of any part, a plurality of supplies are used. Among the chain design proposals, the production cost or procurement cost may be increased up to the maximum value of the production cost or procurement cost of the item of the part included in the supply chain design proposal that satisfies the target cost.

As a result, it is possible to generate an adjustment plan that is highly likely to be realized.

The present invention is not limited to the above-mentioned examples, and includes various modifications. For example, the above-mentioned examples have been described in detail for a better understanding of the present invention, and are not necessarily limited to those having all the configurations of the description. Further, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is possible to add the configuration of another embodiment to the configuration of one embodiment. Further, it is possible to add / delete / replace a part of the configuration of each embodiment with another configuration.

Further, each of the above configurations, functions, processing units, processing means and the like may be realized by hardware by designing a part or all of them by, for example, an integrated circuit.
