一个基于开放式结构的工艺设计知识库系统

摘要

根据工艺设计知识库的开放性要求，提出了一个基于开放式结构的层次化知识库rn模型。在此基础上构造了工艺设计知识库及其管理系统，并给出了工艺知识的综合表示方法和知识库的维护算法。%According to the openness of process planning knowledge base,this paper proposes a hierarchy knowledge base model based on open structure. On the basis of the model, a knowledge base management system for process planning is developed, and a synthetical knowledge representation method for process planning and a maintain algorithm of knowledge base are also given.
