【摘要】 本文介绍一种面向对象的自动工艺设计系统.它采用分层分类方法搜集知识,以产生式规划和与或树结构完整地表达知识,利用规则匹配和深度优先搜索机制进行搜索推理,从而自动进行工艺设计,得到满意工艺规程.该系统设置的外部数据库和规则库,可由用户进行数据及规则的扩充与修改,因而具有较高柔性,可适用于各种环境下的工艺决策.更多还原

【Abstract】 This document describes an automatic process planning system for users. The system collects the knowledge by the different levels and classes. It expresses the knowledge by the If- then rules and AND/OR tree structures. The process planning is antomatically generated by the rule correspondence and the depth priority. This system sets up not only inter knowledge -bank but also outer one. The outer knowledge - bank may be changed and enlarged according to the requirement of the users. So, the system may be used in different environment. It has a better flexibility.更多还原
