Research On Optimization Techonlogy Of Product Design Based On Knowledge System

The research of this paper have regarded knowledge engineering as the foundation, based on the optimization design of knowledge system, faced to the shortage of conventional knowledge base in the complicated knowledge system, regarded improving the automatization and intelligence of knowledge system as the goal, and launched the research on dynamic organization technology of knowledge base.Firstly, the paper has analyzed and summarized the research status in domestic and international. Pointed out that the optimization technology of knowledge base (KB) was a most important technology in KBE. Then provided the research contents and framework of the paper.Secondly, has explained the principle of KBE, discussed the definition, framework, design procedure base on KBE. And has summarized the three-layer frame of KBE.In the theory field, this paper probed a lot, form knowledge to KB. In order to improve the capability of KB, the paper has developed the new concept and technology of organization tactic of KB. Based on the modular and linked organization, this paper has put forward a new technology: dynamic organization based on module. Then discussed the key technologies of the dynamic KB's construction, just like knowledge representation, knowledge acquisition and knowledge management.
