基于知识的分布式设计流管理技术研究

DISTRIBUTED DESIGN FLOW MANAGEMENT BASED ON KNOWLEDGE

在ＣＡＤ集成框架中，建立高水平的设计流管理专家系统是解决分布式设计流管理的有效技术途径．本文提出一种通过建立分布式设计流管理知识库，实现设计流管理的自动化的方法．我们以设计流图为基础，采用基于扩展Ｐｅｔｒｉ网的理论模型描述设计流的动态行为，并将该模型与基于知识的方法相结合，实现了基于知识的分布式设计流管理系统，它能在较高层次管理在分布、异构设计环境下的设计过程．该设计流管理系统在ＹＨＣＩＦ集成框架中得到了成功的应用．

An effective way to solve distributed design process management problem in CAD framework is to build a high quality expert system.This paper proposes an approach to achieve automated design process management through knowledge base.In our distributed design flow management system,we adopt E -petri net model to describe the dynamic behavior of design flow and incorporate the model with the knowledge -based approach.The system can effectively manage design process in distributed and heterogeneous design environment.The design flow management system was applied successfully in YHCIF framework.
