摘要： 该文根据“863”项目“基于知识的箱体CAPP系统”开发经验,提出了一种实用的产生式规则表示和检查方法。通过在规则的条件部分使用嵌套函数,可以表达零件工艺规划中比较复杂的逻辑判断关系,通过对规则的词法检查、语法检查和逻辑关系检查最终保证了从单条规则到整个规则库的正确性和一致性。

Abstract: The paper presents a practical method for checking production rules based on the experiences during the national “863” projectdevelopment. With the use of nesting functions in the “condition” part the rule can express more complicate logic relation. Through the lexical,semantic and logic relation check of the rule, the method guarantees the rightness and consistency from the single rule to the whole rule library.
