装配工艺设计知识表达研究

Research on Knowledge Representation in Assembly Process Planning

为实现知识在装配工艺设计中的应用,从知识在计算机辅助装配工艺设计应用的角度出发,对装配工艺领域知识进行了分析和结构化表达。针对检索、引用以及工艺决策3类应用,对装配工艺通用知识、装配工艺模板知识及装配工艺决策元知识建立了知识库模型,并结合工艺设计系统给出了知识库应用实例,验证了知识库模型的有效性。

In order to realize the application of knowledge in assembly process planning, this article analyzes and structuralizes the knowledge in the domain of assembly process from the perspective of knowledge application in computer aided assembly process planning. Aiming at achieving applications like retrieving, citing and process decision-making, the knowledge base models of general assembly process knowledge, assembly process template knowledge and assembly meta-process of decision-making knowledge are constructed respectively, whose validity is also verified based on a case study on the application of knowledge base in process planning system.
