【摘要】 为把本体理念应用于多Agent的CAPP自动工艺系统,提出了基于本体的多Agent自动CAPP系统模型,并构造了单个Agent的基本架构;建立了该领域的零件本体库和特征本体库,采用基于RDF(S)的OIL语言对系统中的各Agent零件特征知识的语法和语义进行详细的描述与注释,并利用一阶谓词逻辑对各Agent之间本体转换规则的语法和语义加以描述;最后通过实例验证了本体的功能和转换规则的智能推理机制,从而很好地满足多Agent自动工艺系统之间零件特征知识共享、复用和互操作的需求,同时对其它领域知识信息的处理也有着很好的借鉴意义.更多还原

【Abstract】 The ontology-based model of a multi-agent system for automatic computer aided process planning(CAPP) is proposed, and the basic structure of an individual agent is constructed in the model.The ontologies of parts and features are presented in the ontology translation center,and ontology interchange language(OIL) is used to annotate the syntax and semantics of parts features in the model,in which the first-order predicate logic is applied to describe the syntax and semantics of translation rules.Performonce of ontology and intelligent reasoning of tronslation rules are testified finally by the application scenario.Consequently,the model will meet the requirement of sharing,reusing and interoperating of parts features among automatic CAPP systems,and play an important referencial role in knowledge representation of other research communities.更多还原
