Retrieval Technology by Example during Product Development of Auto Parts

In this paper, aiming at the characteristics of auto parts enterprises product development, the object-oriented case knowledge expression to build auto parts product development database is used, the nearest neighbor algorithm is as similarity algorithm of case retrieval, the TCP/IP network technology is as the main network transmission protocol, C/S is as the application system to build the case retrieval system, and EPS steering gear is as an example.
