摘　　要：为了完成基于产品数据管理的计算机辅助工艺设计系统中工艺知识库管理系统的开发,提出了一种基于产品数据管理的工艺知识库管理方法。工艺知识包括工艺资源信息、工艺实例和工艺决策知识三类,据此构建了基于产品数据管理的工艺知识库管理系统的体系结构,提出了基于物料清单的工艺实例表示方法和检索方法、基于数据库中view技术的工艺资源信息的检索方法和基于工艺决策知识三视图模型的工艺决策知识库的维护策略。最后,介绍了样机系统的应用。To develop a process knowledge base management subsystem of PDM-based CAPP system, a PDM-based process knowledge base management method was studied. Process knowledge could be classified as process resource, process case and process decision knowledge. Based on this classification, a PDM-based architecture of process knowledge base was constructed. A Bill of Material (BOM) based representation and indexing method of process case were proposed, a view-technique based searching method of process resource knowledge base was put forward. Based on a model of process-decision-knowledge-3-views, a maintenance strategy of process decision knowledge base was discussed in detail. Finally, the application of the corresponding prototype system was introduced.
