Abstract:
The existing product design system based on case reasoning is
analyzed. Aiming at the shortages of the design system that couldn’t
depict the function and deed of product design case well, a product
design ontology model based on case reasoning is proposed. Product
design case ontology and model are established in terms of ontology
technologies. According to the characteristics of product design
based on case reasoning, the important attributes of ontology model
are studied. The searching method of product design case provided after product design based on case reasoning is analyzed. In the method the appropriate product design case is searched through EDCOM
array and similar degree. In the process of maintenance of ontology warehouse the method on the integration of ontology is given. Finally a product design prototype system based on case reasoning and ontology technology is developed for auto parts enterprise. Through designing requirement, case searching and other functional models, this system realizes product design based on case reasoning.
Key words: Case-based reasoning Ontology
Case searching Similar degree
