可视化产生式系统的设计与实现

Design and Implementation of Visual Production System

产生式系统是最流行的专家系统类型。目前常见的产生式系统,如OPS5和CLIPS,它们的应用和开发界面都是类似LISP的文本界面,可操作性差。文章基于面向对象的方法和技术,设计并实现了一个可视化的产生式系统,该系统采用Rete算法进行推理,提供了事实库、规则库和Rete网络的可视化的维护功能。实际运行表明,该系统效率高,可操作性强。

Production system is the most common expert system.Practical production systems ,such as CPS5and CLIPS,are not operational due to their text interfaces similar to LISP.This paper designs and implements a visual production system in OOP environment.The production system applies Rete algorithm on reasoning,and provides visual maintenance for fact base,rule base,and Rete net.Experimental results show that the system is efficient in reasoning and user-friend-ly in operation.
