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.
