  Below, the processing content by the production planning system 10 is demonstrated.

  First, FIG. 2 shows a use case relating to a production planning system. The user is a production planning unit, sales unit, or manufacturing unit, and first creates a production plan for each production-intensive type based on demand information such as order information and inquiry information (use case 1). Then, a shipping operation is performed based on the production plan for each production-intensive type name created and the shipping instruction for each order type name created based on the order information (use case 2). Also, the production operation is performed based on the production instruction for each production type name created based on the production plan and the order information (use case 3). Thus, in the production planning system 10, it is essential to have a model name master having a relationship between the model names.

  The model name master is stored in the recording means 101 of FIG. FIG. 3 shows an ER diagram of the model name master, and FIGS. 4 to 7 show the contents of the master data. In FIG. 3, the model names are: (1) Order intensive model name: Order model name = 1: N, (2) Order model name: Production model name = 1: N, (3) Production intensive model name: Production model name = 1: N, (4) Order intensive type name: Production intensive type name = 1: N.

  The user also performs a task (use case 4) when a new type name is generated or when the relationship between the type names is changed.

  The structure and format of the master data described above are suitable as the model name master of the production planning system. However, in order to achieve the object of the present invention, the production planning system can have another structure and format. However, the present invention is not limited to the structure and form shown above.

  Next, the processing contents of use cases 1 to 3 shown in FIG. 2 will be specifically described.

  FIG. 8 shows a sequential chart when the production plan system 10 is used to create a production plan, a shipping instruction, and a production instruction.

  First, the production plan creation means 102 creates order-intensive type demand information by aggregation by order-intensive name based on the demand-specific demand information held in the storage means 101 (step S1). Then, it is sent to the input / output means 106 (step S2). And a user inputs a production plan request | requirement with respect to the production plan preparation means 102 via the input / output means 106 based on order-intensive type demand information by name (step S3).

  In response to this, the production plan creation means 102 creates a production-intensive name-specific production plan initial value by disassembly for each production-intensive name, and sends it to the input / output means 106 (step S4). Then, the user inputs a production-intensive name-specific production plan via the input / output means 106 based on the order-intensive name-specific demand information (step S5).

  In response to this, the production plan creation means 102 creates an order-intensive type production plan by name by means of aggregation by order-intensive type name, and stores the order-intensive type production plan by name and the production-intensive type production plan by storage. 101 (step S6).

  Further, the shipping instruction creation unit 103 creates a shipping instruction by disassembly by order type name based on the order-intensive type production plan and demand information stored in the storage unit 101 (step S7). The data is sent to the output means 106 (step S8). Further, the production instruction creating unit 104 creates demand information by production type name by decomposing by order type name based on the demand information held in the storage unit 101 (step S9), and further Based on the demand information by production type name and the production plan (step S11), a production instruction is created by development by production type name and sent to the input / output means 106 (step S12).

  The system operation in this use case will be described below.

  First, a case where a production plan is created will be described.

  FIG. 9 shows an example of demand information. FIG. 9, which is information for each order type name, is processed by the production plan creation means 102, from the order type name in the demand information to the order type name in FIG. The requested quantity is aggregated for each order aggregation type name associated with the order type name. For example, in FIG. 9, the order type name “A123-2” with the request ID “0002” having the same request date and the order type name “A123-1” with the request ID “0003” are the order type name—order received in FIG. As shown in the aggregate name master, both are associated with the order aggregate name A123, so the requested quantities “70” and “40” are aggregated, and the order aggregate name “A123” indicated by the request ID “1002” in FIG. The requested date is “3/11” and the requested quantity is “110”. The result of aggregation for all demand information becomes demand information for each order aggregation type name as shown in FIG.

  Further, the demand information for each order-intensive name is displayed on the screen as shown in FIG. By inputting the number of demand information for each order-intensive name on the screen of FIG. 11 and pressing the “Register” button, the demand information can be changed to the input number.

  Demand information for each order intensive type name (FIG. 10) is obtained from the order intensive type name in the demand information for each order intensive type name to the production intensive type name-order intensive type name master in FIG. The order quantity is processed, and the requested quantity is disassembled for each production-intensive name linked to the received order-intensive name. Here, the disassembly is performed using the following disassembly rules based on the preset distribution ratio.

[Disassembly by preset distribution ratio]
Decomposition according to the preset distribution ratio of the above-described decomposition rule is performed as follows. A flowchart is shown in FIG.

  In step S21, one piece of demand information data for each order-intensive name is selected.

  In step S22, the order intensive type name (J) of the selected data is used, the production intensive type name—the order intensive type name master is processed, and the production intensive type name to be disassembled and the distribution ratio of the production intensive type name are obtained. Demand information for each production-intensive name (Sn) is calculated using the following calculation formula.

Demand information for production-intensive name (Sn) =
(Demand information of order-intensive name (J)) x (Allocation ratio of production-intensive name (Sn))
In step S23, steps S21 and S22 are repeated for the demand information data for every order-intensive name.

  For example, in FIG. 10, the requested quantity “50” of the request ID “1001” and the order-intensive type name “123” is obtained from the distribution ratio of the production-intensive type name—the order-intensive type name master in FIG. Since it is disassembled into 60% for A123-Z and 40% for production-intensive type name “A123-Y”, the production plan for A123-Z is 30, and the production plan for A123-Y is 20. The result of disassembling the demand information for every order-intensive name is the production plan for each production-intensive name as shown in FIG.

  The production plan for each production-intensive name is displayed on the screen as shown in FIG. On the screen of FIG. 14, the number of production plans for each production-intensive name is input, and by pressing “Register”, the number of production plans can be changed to the input number.

  Next, a case where a shipping instruction is created will be described.

  The production plan for each production-intensive type created by the production plan creation unit 102 (FIG. 12) is obtained from the production-intensive type name in FIG. The production plan is gathered for each order-intensive type name associated with the produced production-intensive type name by mastering the production-intensive type name of the master. The result of consolidating the production plans for all production-intensive names is the production plan for each order-intensive name as shown in FIG.

  Then, from the production plan for each order-intensive type name and the order information for each order-type name, the shipping instruction creation means 103 causes the order type name in FIG. In order to divide the order into the production plan linked to the production plan linked from the order-intensive name associated with the ordered order name. The result of dividing all orders is a shipping instruction for each order type name as shown in FIG.

  The shipping instruction for each order type name is displayed on the screen as shown in FIG.

  Next, a case where a production instruction is created will be described.

  Demand information for each order type name is obtained from the order type name in the demand information by the production instruction creating means 104, and the order type name in the production type name-order type name master shown in FIG. Demand information is disassembled for each production model name associated with. The result of performing the decomposition on the demand information for each order type name is the demand information for each production type name as shown in FIG. In the example of FIG. 18, the demand information for each order type name is decomposed into demand information for each production type name based on a preset distribution ratio of production type name-order type name master in FIG.

  Then, the demand information for each production type name and the production plan for each production-intensive type name are produced from the production type name in the demand information by the production instruction creating means 104 in accordance with the production type name-production-intensive type name master shown in FIG. Demand information is disassembled for each production-intensive type name associated with the produced production type name. The result of performing the decomposition on the demand information for every production type name is the production instruction for each production type name as shown in FIG. The disassembly rules at this time include a rule that (1) a production plan date is a production instruction and (2) a request date is a production instruction. In FIG. 19, the disassembly is performed according to the rule (1). Production instructions are disassembled on the production plan date when demand information is assigned for each model name. Production instructions for each production type name are displayed on the screen as shown in FIG.

  Next, a case where a model name is registered will be described.

  The model name can be registered by the user on the model name master registration screen as shown in FIG. FIG. 21 illustrates a case where an order intensive model name, a production model name, and a production intensive model name are registered when an order model name is determined. The user registers the order-intensive name associated with the order-type name, the production type name associated with the order-type name, the registration of the production-intensive name associated with the registered production type name, and the registered order-intensive type Register production-intensive names associated with names. When the “register” button is pressed by the user, the model name consistency holding unit 105 checks whether the relationship shown in FIG. 3 is maintained.

  Regarding the order intensive type name, the order intensive type name in FIG. 4—order intensive type name master in FIG. 4 and the production intensive type name—order intensive type name master in FIG. Name: Order-type name = 1: N, Order-intensive type name: Production-intensive type name = 1: N. If not, an error message is displayed on the screen.

  As for the production model name, the production model name in FIG. 5—order type model name master and the production model name—production intensive model name master in FIG. It is confirmed whether type name = 1: N, production intensive type name: production type name = 1: N, and if not, an error message is displayed on the screen.

  As for the production intensive type name, the production type name shown in FIG. 6—the production intensive type name master and the production intensive type name—the order intensive type name master shown in FIG. It is confirmed whether the aggregate type name: production type name = 1: N, the order aggregation type name: production intensive type name = 1: N, and if not, an error message is displayed on the screen.

  If all the relationships are confirmed, it is registered in the model name master.
