Distributed Knowledge-Based Product Design

The knowledge-based product design was analyzed in this paper firstly. Aimed the shortages that the knowledge of the existing system for product design was close and the distributed knowledge couldn´t be integrated and shared, a novel distributed knowledge management system framework for product design was proposed. The main layers were studied and the key technologies of system were discussed. Ontology-based knowledge share is proposed. Knowledge ontology and knowledge ontology model are defined in terms of the design knowledge´s characteristic. A novel model searching method based on ontology is proposed, where the appropriate parts model was searched through EDCOM array and similarity. Finally a distributed knowledge management system is developed on the basis of prior analysis and about an example about eddy current retarder design based on the prototype system is given.
