基于产生式规则专家系统在结构损伤诊断中的应用

工程结构损伤诊断过程复杂,信息源要求广,而且该领域专业知识零散,不成系统.针对此现状,将知识工程领域中应用成熟的专家系统技术引入结构损伤诊断领域,利用专家系统的知识库及推理机制,不仅能协助专家进行现场作业,而且能够整理、保存和推广应用结构损伤诊断领域的专业知识.介绍了采用产生式规则的知识表示模型和面向对象的知识表示方法,也介绍了基于产生式规则专家系统的设计思路,以及结构损伤诊断专业知识的处理方法,并利用Visual C++6.0实现了具有实际应用价值的结构损伤诊断专家系统.

Application of Expert System Based on Production Rule to Structure Injure Diagnosis

Structure injure diagnosis is complicated,which needs a lot of diagnosis information,and the knowledge of this field is scattered.According to this,the expert system technology which used widely in knowledge engineering is applied to the structure injure diagnosis.With base and reasoning mechanism of expert system,the system not only can help human expert diagnose the structure injure,but also can arrange,save and apply the specialized knowledge of structure injure diagnosis.The paper firstly explains how to build the expert system and how to deal with the specialized knowledge,the knowledge expression model of production rule and the knowledge expression method of object oriented,and then builds the expert system which has practice application worth with Visual C++ 6.0.
