System and method for predicting the error quotient of a product

摘要

A defective ratio evaluation method includes a step (100) of classifying defective information describing product structure and manufacturing features which become product defective occurrence factors and making the defective information accessible, a step (110, 120, 130) of comparing design information of a product to be evaluated with the detective information, computing types of defective information and a number of defective information items included in the design information, and computing, using the types of defective information and the number of defective information items thus computed, a degree of occurrence of an event in which the evaluation objective product becomes defective; and a step (140) of displaying the degree of defective occurrence thus computed.
