Abstract: Customer-centered reusable design is one of important feature of DFMC (Design for mass customization). Design retrieval is one of the key technology for design reuse. In allusion to insufficiency of design retrieval based on similarity , the Neural Network is introduced into design of case retrieval and a model based Neural Network is proposed. By modeling for the fuzzy requirement information, the model for design retrieval is more adapt to the design reuse engineering fact. Simulation and practical application show that the design retrieval method based on Neural Network is better and more effective than the general method based case similarity, especially in the design retrieval for fuzzy requirement information, the retrieval result is more flexible.

Key words: Customer-centered design, Design retrieve, Design reuse, Fuzzy mapping, Neural Network
