【摘要】 随着电子、电气、通讯、航天等行业的日益发展,对继电器的设计要求也日趋复杂,继电器产品种类更加繁多。如何根据客户的要求,更加快速、合理地设计出合乎要求的继电器,已经成为继电器厂家在竞争中取胜的关键。本文结合人工智能的方法,将基于实例的推理(CBR)的研究应用到继电器产品的设计上来,这将对电器产品的智能设计产生积极意义。基于实例的推理在其它领域已经有很多成功的案例,在继电器产品设计上还鲜有研究。所谓基于实例的推理就是通过利用以往求解相似问题的以实例形式表示的经验知识进行推理,来获得当前问题求解结果,是符合逻辑的科学的推理方法。模糊CBR就是在CBR基础上考虑了模糊因素。本文讨论了基于实例的推理的关键技术,以及其实现方法。基于VB和数据库技术,采取相应的实现技术和相似度计算方法,实现了对CBR系统的软件编程。对于模糊CBR关键问题—相似度的计算,提出了一种建立在当前两种常用的贴近度的基础上的新的贴近度算法,通过具体的实例验证了其计算的合理性。更多还原

【Abstract】 Along with electron electric communication and spaceflight developing day by day, the requirement to relay is more and more complex and the category of relay is much more various. How to design satisfying relay fastly and reasonedly, according to the requirement of client , already become the key that relay companies get victory in the competition.Combining with the method of artificial intelligence, CBR method is applied to the design of relay product in this paper ,that will bring advanced meaning in some degree. Case-based reasoning has gotten some successful case in some other domain, but there is few study in relay product design. What is called case-based reasoning is that through using the experience and knowledge that is used to explain problem as case expressed to reason to get the problem result ,and it is logical and scientific reasoning.This paper discussed the key technique of case-based reasoning and its method to realize. It brought forward a new method to compute approach degree that is based on two current usual approach degrees and validated its computational rationality through the material example . At last, we realized the software program that is based VB and data base technique with the conventional technique and figure method of similar degree.更多还原
