摘要
介绍了基于案例、规则和模型的预报推理方法 ,比较了各种预报推理方法的优、缺点 ,提出了基于案例、规则和模型的混合推理。同时讨论了贴近度的定义、表示和计算以及规则表示等问题。最后给出了系统的功能和实现方法。应用证明基于知识库的锅炉“四管”
The predictive methods based on case,on rule and on model are introduced in this article.Comparing with each other,advantage and disadvantage of these reasoning methods are obtained.Thus the mixed reasoning based on case,rule and model is posed.At the same time,the definition,representation and calculation of the degree of similarity and rule representation are discussed.The function of system and way of realization are also described in the paper.It is proved by application that expert system of 'four tube' crack prediction based on knowledge base can achieve the same predictive result as the expert.
