Design Quality Review System Based on Design-rules and Fault Document Databases for Motors

Abstract

For the purpose of improving product design quality, we have developed a system that supports to manage effectively trouble information with a browser based fault tree diagram editor. We also developed another system that systematizes empirical design knowledge and design know-how's as a set of design rules. This expert system generates design review items that are necessary and suitable to be applied to the product designs of interest. These two systems share a function that translates trouble information into design review items, so that the re-occurrence of similar troubles can be avoided.
This paper presents the concept, the implementation, and the benefits of the systems. The evaluation is based on an actual use in the design and quality assurance activities of large scale DC and Induction motors.
