Research on Design Knowledge Retrieval Based on Matlab and VB Language

摘要

When developing new product, in order to shorten new product development cycle, to reduce the design cost, design engineers need to look for the existing design knowledge for reuse. In the process of reuse, the first thing to do is obtaining and searching design knowledge; then, excluding useless and not related knowledge; searching out the most similar case with new products, including basic parameters, the basic principle and so on. In this paper, Matlab is combined with VB language, and on the basis of similarity principle a case library is designed. It is easy for the designers to retrieve the required information. An example has been used to verify the effectiveness of the proposed method and the simpleness of operation.
