摘要
从建立专家系统的角度对JB4708-2000、JB/T4709-2000、JB4744-2000国家标准中焊接工艺知识进行了归纳总结,将焊接工艺知识按特点分为事实性知识、定义性知识、规则性知识、过程性知识和描述性知识,并针对不同类知识建立了其知识表示方式;采用基于规则的推理过程,推理机不再单独出现,规则嵌入对象与对象之间,与知识库合并一同存在于知识库中。
Based on summarizing welding process knowledge in national criterion of JB4708-2000,JB/T4709-2000 and JB4744-2000 from the point of establishing expert system.It classifies five kinds of welding process knowledge(verity knowledge,definition knowledge,regularization knowledge,process knowledge and description knowledge)and establishes the knowledge expression styles accordingly.In this article,reasoning procession based on rules,the inference engine and the rules are not showed separately but embed between objects,lie in the knowledge base.
