摘要
针对铁路车站信号设备故障诊断专家系统开发的目标要求,基于面向对象的结构化知识表示方法,对故障诊断知识库的设计与实现进行了研究。分析面向对象知识表示方法的基本构成及特点,并结合实例介绍原型知识库的设计与实现方法。实际应用分析表明,采用面向对象的结构化知识表示方法不仅可增强故障诊断专家系统的知识表达能力,而且有利于对大量专家知识的组织。
According to the goal in the Diagnose Expert System for railway station signal equipment, it was adopted objectorient structural knowledge representation in the design and implementation of knowledge database for Diagnose Expert System. It was analyzed the constitution of object-orient knowledge representation and its features. Meanwhile, by the concrete example, it was also explained the designing and implementing method for original knowledge database. After the actual operation in this expert system, It was find that object-orient technique not only enhanced the representation in expert knowledge, but also benefited the organization for expert knowledge.
