2. Description of the Related Art Conventionally, an assemblability evaluation system has been realized. This applies the assemblability evaluation master (a table in which check points are set for each evaluation item and the evaluation points are associated) for each of the element parts that make up the product, and each item of the evaluation master is applied for each element part. The detailed evaluation information corresponding to the above, the assemblability index of the corresponding element parts calculated from the detailed evaluation information, and the assemblability evaluation result of the entire product obtained by integrating them are obtained.

On the other hand, CAD has been conventionally used as a design support system. This has made it possible to construct a design information database consisting of product materials, shapes, dimensions, and the like.

However, there is no system that can refer to the design case of the design information database corresponding to the evaluation data of the assemblability evaluation system.

Therefore, even if it is inferior as a result of the evaluation of the assemblability, the only way to devise an improvement plan is to find out the knowledge possessed by the designer from the range of experience. .

The new evaluation information storage unit 10 stores the results of evaluation by the assemblability evaluation unit 6 of the assemblability evaluation system unit B with respect to the element parts for which improvement cases are to be output.

The assemblability evaluation case temporary storage unit 11 temporarily stores an evaluation case to be compared from the assemblability database 7.

The comparator 12 compares the content of the information section of the new evaluation information storage section 10 with the content of the information section of the assemblability evaluation case temporary storage section 11.

The comparison result storage unit 13 stores the evaluation information selected by the comparator 12 so as to be passed to the design case search unit 9 in the next stage.
