Alternatively, a predetermined software is installed on a server, and a client machine connected via a LAN or the Internet gives a predetermined command,
The server may execute the process and return the result.

As shown in FIG. 1, the I / F 12 includes a company name / company name specifying section 24 for specifying a company name or a company name that constitutes the SCM model based on a user input, and a company (company) to be set. ), Business conditions, sales conditions, inventory conditions,
Further, it has a sales condition setting unit 26, an inventory condition setting unit 28, and a procurement / production condition setting unit 30 which respectively set the procurement / production conditions. The I / F 12 is SC
It has a link setting unit 34 that forms links between various business operators and business offices that make up the M model and grasps them.

The view generating unit 14 generates a condition input view including a question item for the user and an input field for inputting an answer to the question item, and an SCM according to the user's input. A model view generation unit 3 for generating a model view in which a model is made into a figure
8 and.

The operation of the CSM design support system thus configured will be described in more detail. 2 and 3 are flowcharts showing an example of a user's input procedure to the input field displayed in the condition input view and a processing procedure in the I / F 12. 2 and 3,
The procedure in the figure surrounded by the broken line 200 is input by the user, and the procedure in the figure surrounded by the broken line 210 is I / F.
The processing by 12 is shown. In the present embodiment, initially, the condition input view generation unit 36 sequentially generates the views as shown in FIG. 2 for which an input is requested so that the user can guide the model generation.

First, the condition input view generation unit 36 specifies the name of the business operator that is the center of the model, basically the business operator (company) or business office that designs the CSM model and executes the simulation. A condition input view including an input field for inputting and an input field for the product name to be evaluated is generated, presented, and the user is requested to input (steps 201 and 202). The user operates the input device 20.
Operate to enter the necessary items (company name or business office name) and the product name to be evaluated.
In the present specification, the input by the user includes directly inputting a numerical value or a character string using a keyboard and selecting a predetermined one from candidates shown by a pull-down menu or the like. As a result, the company name / business office name specifying unit 24 stores the input company name or business office name in a predetermined area of the user input information / history DB 18. As a result, inventory management points (hereinafter, also referred to as "PSI points" depending on the case) are set (steps 211 and 212). The model view generation unit 38 also generates a model view including the symbol of the set PSI point.

FIG. 4 is a diagram showing an example of an image including a conditional input view for which an input is made in steps 201 and 202 and a model view obtained by the input. As shown in FIG. 4, in the condition input view 401, a company name or establishment name input field 411 and a product name input field 412 are displayed.
Is included. When the necessary information is entered in the above input fields,
The model view generation unit 38 generates the view 402 including the symbol 421 of the PSI point according to the input information and the explanation column 422 attached to the symbol indicating the input product name. Thereafter, in the present embodiment, in response to sequentially inputting information in the condition input view, symbols, links between symbols, and an explanation column associated with symbols are added to the model view.

Next, a process for creating a PSI point located downstream of the initially created PSI point is executed. Here, in the condition input view,
An input box for inputting the sales destination is arranged, and the user operates the input device 20 to input the names of the distribution destination / sale destination of the product to be sold (step 203). In response to this, the I / F 12 stores the input information about the distribution destination / sales destination in a predetermined area of the user input information / history DB 18. As a result, the distribution / sales destinations are set as PSI points (step 213). FIG. 5 is a diagram showing an example of images of the condition input view and the model view in step 203. In the condition input view 501, a distribution / sales destination input field 501 is provided. Also, in the model view 502, the newly created P
SI point symbols 521 and 531 are displayed, and explanation columns 522 and 532 of the products to be evaluated, which are associated with the respective symbols, are also displayed.

Further, the PSI point symbol 421
Inside, the “S” box 512 is the PS of the distribution / sales destination.
It will be appreciated that it is linked to the "P" box of I points (see 513, 514). This is the supply of PSI points (Supply) corresponding to the business operator who is the main body that executes the simulation, and the production and procurement of PSI points of distribution and sales destinations.
urement) is associated with.

The process of setting the PSI points of the distribution / sales destinations will be described in more detail with reference to FIG. When the company name or the office name is input using the condition input view (see reference numeral 501 in FIG. 5) (step 60)
1) In the user input information / history DB 18, a record relating to the input company name or business office name is generated (step 602). In addition, in the record of the company, that is, the business operator who is the subject of the simulation execution,
Information on the sales destination is added, and the record of the company concerned and the generated record are linked (step 603). Then, based on these pieces of information, the model view generation unit 38 is located downstream of the symbol of the company,
At the same time, a model view is generated in which the "P" box includes the PSI point symbols of the distribution / sales destinations that are linked to the "S" box of the company (steps 604 and 605).

Next, the condition input view generation unit generates a condition view having an input field for inputting information on the transaction form with the distribution / sales partner and transaction conditions, and the user inputs necessary information. Ask (step 204). 7 and 8 show images including the condition input view 701 and the model view 602 at this stage. Figure 7
As shown in FIG. 7, in the condition input view 701, the transaction form and transaction conditions (for example, annual sales amount, order frequency, delivery date, etc.) between the company and each supplier / seller can be entered. There is. Further, the presence / absence of preliminary information between them and, if the preliminary information exists, the preliminary information can be input. Preliminary information is based on the agreement between the company and its business partners / sales partners.
Prior to receiving an order, it refers to information such as expected orders to be exchanged with business partners / sale parties in advance. Further, in the image 800 shown in FIG. 8, the condition input view 801 shows a sales forecast of a distribution destination / sales destination, a sales plan (for example, sales results by day, week, etc., sales forecast by day, week, etc.). And the difference between the plan) can be entered.

When information is input to such a condition input view, the input transaction information is displayed in the model view 702 in association with each symbol (see reference numerals 713 and 732).

Next, the input relating to the production base and the processing associated therewith are executed. The setting is executed by inputting the production base / production item and the production lead time of the product to be evaluated (step 205). In response to these inputs, the production base is set as the PSI point, and the production item and the production lead time are registered.
Further, a BOM (Bill Of Material) of the production item is automatically generated (step 215). In the example of orange juice, the orange juice production base is set as the PSI point, and the required packaging material (for example, a can) is input by the automatic generation of the BOM. The image 900 shown in FIG.
In the condition input view 901, the target PS
It is questioned whether I-point is producing.
If you input "No" here, another P
SI points are generated, and various information can be input at the PSI points. In addition, the production form and constraints can also be entered here (step 301,
311).

In the example of FIG. 9, in the condition view 901, "manufacturing (processing)" is designated at the target PSI point (symbol 421 in the model view 902), so the symbol 421 is designated. Information about the production plan of the corresponding PSI points is entered.
By this input, the production item and the production plan are displayed in association with the symbol 421 in the model view 902 (see reference numerals 912 and 913).

Next, the procurement item, the procurement destination and the procurement lead time necessary for the production of the merchandise, which are obtained by the automatic generation of the BOM, are input (step 302). In response to these inputs, the supplier is set as the PSI point. Further, the procurement item and the procurement lead time are registered (step 312). Here, the PSI point of the production base and the PSI focus of the procurement base are linked. In addition, the BOM of the procured product is automatically generated if necessary.

As shown in the image 1000 of FIG. 10, the BO
A condition input view 1001 for setting a supplier and a procured item name of the raw material / part obtained by the automatic generation of M is displayed, and the operator may input or select the supplier and the procured item name. This allows the model view 1
002 is a symbol 10 indicating the PSI point of the supplier.
11, symbol “P” of symbol 412 and symbol 1011
A link 1012 connecting the “S” mark is formed, and the product name sold at the PSI point of the supplier is displayed (see reference numeral 1013).

Further, the operator refers to the condition input view (see the condition input view 1101 in the image 1100 of FIG. 11) displayed after the input of the supplier and the name of the procured product, and refers to each of the supplier and the procured item. Information on the transaction form and transaction conditions can be entered (step 303). This information is user input information / history D
It is stored in B18 (step 314).

In this way, various information relating to the PSI points of the products to be evaluated by the company (in the illustrated example, the distribution / sales destination of “orange juice (can)” and the raw material / parts procurement source, and If necessary, various information regarding PSI points of other production bases is input, and these information are user input information / history DB1.
When registered in 8, the operator inputs the transportation lead time between PSI points according to the condition input view (step 304). The input transportation lead time is stored in the user input information / history DB 18 (step 315). In the image 1200 shown in FIG. 12, the transport lead time between the set PSI points can be input in the condition input view 1201, and when the information is input, the PSI points are displayed in the model view 1202. The input lead times are displayed in association with the links between symbols (see symbols 1211, 1212, and 1213) (see symbols 1221, 1222, and 1223).

When the transportation lead time is input in this way, the condition input view 1 in the image 1300 of FIG. 13 is input.
An input field for inputting conditions relating to safety stock is displayed at 301, and the operator refers to the safety input view to determine whether or not the safety stock is set at each PSI point, and when the safety stock is set. It is possible to select whether it is a period (number of days) setting or a quantitative setting. These input or selected information are
It is registered in the user input information / history DB 18 (steps 305, 315).

In this way, the basic SCM model is generated. In order to generate a basic PSI model, as described with reference to FIGS.
The condition input view is sequentially presented to the operator by F12, and the operator only has to input or select necessary information in the input field in the condition input view. The user can also specify a symbol displayed in the model view and set a new PSI point upstream (procurement source) or downstream (sales destination / distribution destination) of the symbol. For example, when an “S” mark of a distribution destination symbol (see, for example, reference numeral 521 in FIG. 7) is designated and generation of a new PSI point is instructed, a new PSI point located downstream of the distribution destination PSI point is designated. Regarding PSI points of various sales and distribution destinations,
A condition input view for inputting various information is displayed. The operator may enter necessary information in the fields in the condition input view. Similarly, for other PSI points, if the "P" mark of a certain symbol is specified, the PS
A PSI point located upstream of the I point can be generated.

If the operator wants to change the information at each PSI point and change the simulation condition accordingly, the operator may specify, for example, a "change simulation condition" button 1303. As a result, it becomes possible to return to the desired condition input view and input new information in the condition input view.

When the basic SCM model is completed,
Alternatively, at the stage where the desired correction and addition of PSI points are completed, for example, “simulation execution” is performed.
When the button 1304 is designated, the simulation is started. In the present embodiment, the stock level including the safety stock amount at each PSI point is calculated using various information input using the condition input view as a simulation condition. For example, the safety stock calculation is
"Nikkei Bunko (140) Knowledge of inventory management (written by Yukio Mizuno, published by Nihon Keizai Shimbun, Inc., 1945)". Here, the quantity SS of safety stock is represented by SS = K · σ _L (= K · (√L) · σ). Here, σ _L is the standard deviation of the prediction error during the lead time, and K is a safety factor.

FIG. 14 is a diagram showing an example of a view showing a simulation result. The simulation result view 1401 is preferably arranged above the model view instead of the condition input view. In the simulation result view 1401, the theoretically appropriate safety stock level (stock period or stock quantity) of the PSI point where the safety stock is “present” is displayed. On the other hand, in the model view, as shown in FIG.
A graph 1500 in which a current inventory level 1501 and a theoretically appropriate safety inventory level (calculation result) 1502 are arranged side by side is displayed in association with the point symbol 421. Of course, for other PSI points as well, the current inventory level and the theoretically appropriate safety inventory level are displayed side by side. The result of the simulation is stored in the user input information / history DB 18.

The operator can change the information about the PSI points and repeat the simulation while referring to the model view. At this time, referring to the model view, desired information may be input or selected in the input field of the condition input view as shown in FIG. 4 to FIG. It becomes possible to input.

According to the present embodiment, those who do not have SCM expertise are guided by the condition input view,
It is possible to generate an SCM model and execute a simulation. Further, it is possible to easily change the simulation condition by re-inputting the information in the condition input view. The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and those are also included in the scope of the present invention. Needless to say.
