【Abstract】 In order to resolving the problem of representing part’s knowledge, decompose the part’s knowledge into public and private knowledge of part, body and surface. And then use semantic network to represent the knowledge of features for its merit of powerful reasoning capability. In this paper, the method of using semantic network to represent feature based knowledge of part is set forth, and through example, it is demonstrated the reasoning process of this semantic network generating process plan.更多还原
