Next, the operation of the apparatus constructed as described above will be described.

Market / Customer 10 Demand Forecast 1
1. The manufacturer makes an overall sales plan based on the budget plan. In the sales plan, it is not always necessary to calculate the planned number for all the product models, and the plan may be created by substituting several typical product models. Then, a production plan is created based on this sales plan. This also has a strong meaning to grasp the overall quantity such as allocation of production resources, so it is often created based on the product model used in the sales plan, but it can also be created in units.

In the following, description will be made by taking a product model as an example.

The unit configuration expanding function 21 has a function of selecting the units 1, 2, and 3 to be used, and the production planning / sales planning data 2 of the product from the demand forecasting database 24.
4a and unit configuration data 24b for each product model for procurement
Is read out, the total number of units 1, 2, and 3 required for production is calculated from the quantity of each product model configured by the combination of the selected units 1, 2, and 3, and The parts table is read from the parts table database 23. Then, the supplier 13 is informed of the quantity of the units 1, 2, and 3 and parts arrangement based on these parts lists.

That is, the unit configuration expanding function 21 calculates the unit requirement amount necessary for the product model of the production plan. Based on the calculated required amount, a product model other than the representative product model is added or a specific unit required amount is adjusted as necessary. At this point, the production plan is
It is treated as a unit-based plan rather than a product model-based plan. The quantity planning in product model units is basically referred to for rough planning such as production resource allocation, but the actual production planning is based on unit requirements.

Next, the parts required for production are procured. The required quantity used for procurement is obtained by developing each unit parts bill based on each unit requirement calculated in the production plan, not on a product model basis. Procured parts are stored as inventory after procurement or after unit manufacturing.

Next, the product model to be produced and its quantity are determined. In the case of ordering and assembling according to customer-requested specifications, selection of units according to customer specifications and production plan / order data including the quantity of a product model including these units are determined based on orders from customers. Of course, the same procedure can be used for planned production by selling through a retail store.

Next, the product model structure expanding function 22 reads out the product production plan / order data 12 stored in the production plan / order database 26, and based on the production plan / order data 12, the parts table database. 23, the unit parts table data 23a and the unit parts table data 23b are registered in the units 1, 2, 3 and the part a,
b, n, ..., P are read. Then, a product model parts table (manufacturing plan / instruction database 27) that defines all the parts a, b, n, ..., P constituting the product is generated, and this manufacturing plan / instruction data 28 is processed / assembled into the product. It is given as a manufacturing instruction of the product to step 16 of.

That is, the product model structure expanding function 22.
Generates a product model parts table required for final assembly of the product from the order data. In this product model parts table, all parts of the product model manufactured by the manufacturing mode may be expanded, or some or all of the units may be extracted as another parts table.

For example, as shown in FIG. 3, a unit is selected from the model parts table, and the product model α-1 has units 1, 3,
6 ..., the product model α-2 is a unit 2,
5, 7, ...

Next, the final process and assembly of the product are performed based on the product model parts list, and the product is completed and shipped.
As a manufacturing form, a case where a product is manufactured at once from individual parts and a case where all or some of the units are manufactured in advance,
The unit may be assembled in the final assembly process.
The unit manufacturing includes a method of establishing a manufacturing plan in advance and a method of manufacturing by a subsequent process such as Kanban.

Next, the production plan is adjusted according to the shipping status of the products. At this time as well, the planned quantity is increased or decreased in units of product models.

As described above, in the first embodiment, the model parts table in which each model of the multi-specification product is registered,
And a unit parts table in which a plurality of units each including at least one part are registered, and between these model parts table and the unit parts table, each model of the multi-specification product has one of a plurality of units. Since the relationship of being configured by combining these units is shown, it is possible to manage the parts of all models of the multi-specification product, with one model as the head. As a result, even if the number of parts bills increases, the burden required to manage each part can be reduced, and the parts of the multi-specification product can be efficiently managed to improve productivity.

Furthermore, since each model of the multi-specification product is configured by combining any one of a plurality of units, the production plan is switched for each model of the multi-specification product, or a sudden change in demand occurs. In addition, it is possible to easily manage parts of multi-specification products.

Further, the multi-specification product is divided into a plurality of units constituting each model and registered, and at least one component constituting the unit is registered in the lower layer of these units,
When an order for a product is received, units are selected and combined according to the contents of the order to create a product model parts table.

Therefore, even if the number of parts bills for a multi-specification product becomes enormous, the parts bill management is simplified, the procurement work is simplified, and the manufacturing work efficiency is increased without increasing the burden of managing the parts bill. Can be converted.

Further, regarding the parts table management, it is only necessary to register and change the parts table for each unit and the two types of parts table showing a selectable unit set for each model as an upper layer of the product model. A parts table for each model can be automatically generated as needed, and management of the parts table can be greatly simplified. Also, at the time of design change, the necessary product model BOM can be automatically generated by changing the design only for the required units. Therefore, it is necessary to manually manage the change for each product model BOM as before. There is no.

Also in the procurement work, the procurement unit of the materials required for production is not limited to the product models of many kinds,
Since it is performed in units of limited types, the procurement work from the supplier 13 can be greatly simplified. In particular, if there is a discrepancy between the demand forecast and the actual demand, it is possible to finely procure additional components or discontinue the procurement in units rather than in product model units, so it is possible to prevent extra component arrangements and inventory increases. Also, in the case of planned production, even if the sales volume of the model that is expected in the initial plan does not increase, there are cases where the unit arranged for this model or product model can be diverted to another model. Can reduce losses.

In order to improve the efficiency of manufacturing operations, since each product model parts table necessary for manufacturing can be automatically generated from the production plan / order data, it is necessary for the person in charge of manufacturing to manage the parts table for all product models to be manufactured. Is eliminated and efficiency is improved. This eliminates the need for the manufacturing side to change the bill of materials for each product model due to the design change. Furthermore, the parts list of the product model is compatible in manufacturing and is managed for each unit, so all or some units are created in advance and assembled into a finished product at once in accordance with the order. The manufacturing method is easy. This is particularly effective in reducing the manufacturing lead time.
