摘要：The conceptual design of products is an important stage in the design process. However, how to reuse the existing and successful parts is always the key factor to the success of products in the process. To match the case parts rapidly and accurately, this paper puts forward the case-based reasoning (CBR) technology based on functional mode, which expresses accurately the functional structure through the generalized positioning of parts in products. Also, the scheme of variable-length hierarchical coding of functional mode is proposed, and the analytic hierarchy process (AHP) is adopted to determine matching function. Then, based on the hierarchy retrieval mode, the accurate matching of case parts is realized. The application of instance shows that the matching mode is feasible.
