PROBLEM TO BE SOLVED: To study a mounted product plan in which all the factors in the production are totally evaluated, and avoid a large management loss and a large plant operation loss when the actual production is started. SOLUTION: In a stage in which a mounting method and a mounting board construction are studied in accordance with a mounting method data base 2, a mounting method study algorithm 5 and a mounting board construction study algorithm 6, the proper mounting costs of the respective types of components are multiplied by the mounting numbers of the respective components in accordance with a mounting cost data base 3 and a mounting cost study algorithm 7 to obtain a total mounting cost. Then, proper mounting tacts for the respective types of the components are multiplied by the mounting numbers of the respective components in accordance with a machine characteristics data base 4 and a production capability study algorithm 8, and divided by the proper mounting capabilities of machines to obtain the production capability. Thus, the total mounting cost and the production capability are simultaneously studied.

[0002]

2. Description of the Related Art Conventionally, a method as shown in FIG. 11 has been adopted when planning and deciding a product to be mounted. First, regarding the mounting method and the mounting board configuration that have the greatest impact on the contents of the study, regarding the mounting method, if a proven product has already taken the insertion method, the insertion method is used as it is, and the surface mounting method is used. If so, adopt the surface mounting method as it is,
Regarding the mounting board configuration, the area of products already proven,
It has been determined based on the intuition and experience of the designer based on the number of sheets, mounted components, and the number of layers.

[0003] Regarding the study of mounting costs that greatly affect the management of the mounting factory, the total number of mounting points is multiplied by the uniform standard mounting cost from standard and easy-to-mount square chip parts to odd-shaped and difficult to mount QFPs and connectors. It was done by.

[0004] In addition, regarding the study of the production capacity that greatly affects the operation of a mounting factory, the standard mounting tact set for all the different types of mounting parts is multiplied by the total mounting points, and the parts to be mounted and the mounting parts are originally determined. This is done by dividing the mounting capability that can vary depending on the machine productivity or the like with respect to the difficulty level by uniformly representing the standard mounting capability of the machine.

[0005]

However, in the above-mentioned conventional method, it is necessary to first determine a mounting method and a mounting board configuration, and all elements in production such as mounting cost and production capacity are not totally evaluated. Therefore, there is a problem that the mounting method and the mounting board configuration are not always optimal.

In the study of mounting costs, there is a problem that accuracy is poor because all components are estimated at the same standard mounting cost, and there is a large risk of causing a large management loss during actual production.

[0007] Further, in the study of the production capacity, there is a problem in that since all parts are calculated using the same standard mounting tact, accuracy is poor, and there is a large risk of causing a large mounting factory operation loss during actual production. .

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention considers both the total mounting cost and the accurate production capacity at the stage of examining the mounting method and the structure of the mounting board at the same time. The purpose of the present invention is to provide a mounting product planning and review system that can examine mounting product planning that totally evaluates and does not cause a large management loss or factory operation loss during actual production.
