Modeling of Product Functional Model in Conceptual Design based on Case-based Reasoning

The modeling of the functional model has been researched by using case-based reasoning (CBR) in conceptual design. On the basis of the describing of the functional model and the coding of the product functionthe functional nodes and the edge have been matched. The functional model which has the most high similarity has been searchedthen the nodes and edges have been modified to meet the design require. Based on the above two kinds of technology and follow the design principle of multi-agent cooperation solving system and CBR working procedure, a multi-agent system architecture which adopt a strategy of task harmonize and based on hybrid structure is put forward. The functional model can be established to meet the companys ability in the conceptual design stage by using the methods in this paper.
