摘　　要：该文简要介绍了采用ＰＤＣｐｒｏｌｏｇ语言开发的一个高档微机故障诊断专家系统。该系统基于一种新的不确定推理模型，采用正反双向推理机制综合进行高效推理，不仅提供了智能的知识获取工具，而且还具有时推理过程的解释和帮助机制。该系统将推理机与知识库相分离，实现动态模块化的知识库管理与分层推理，并且具有清晰美观、便于操作的人机界面，可以方便地实现对两大故障类、八大故障部位进行有效合理的诊断。This paper introduces a higher micro-computer breakdown diagnosis expert system developed with PDC prolog language.This system is based on a new nondeterministic inference model,and can infer high-effi- ciently with forward and backward inference system.It not only provides an intelligent knowledge collection tool, but also possesses an explanating and helping system to inference procedure.The inference machine is separat- ed from the knowledge- base in this system.It realizes dynamic and block-structured knowledge-base manage- ment and levelling inference,and has a clear and beautiful human-machine interface which can be operated easily.It can diagnose conveniently,efficiently and reasonably two kinds of breakdown and eight breakdown parts of micro-computer.
