A Method of Engineering Case-Based Reasoning-Comprehensive Evaluation

This paper discusses the thoughts of design experts in case-based design. A methodof case-based reasoning-comprehensive evaluating, which simulates the experts' designingthoughts, is presented in this paper. Based on a fuzzy matching model and a fuzzy evaluatingmodel, a multi-layer model is provided for quantiative discription of the similarity at differentlayers. This method has been used in the development of engineering intelligent CAD kmelsystem.
