摘要: 提出了一种基于粗糙集理论的决策规则获取算法及实用的决策规则表示方法。产品智能设计系统中,在概念设计阶段需要决定产品的类型。一般的产品设计过程,是从分析用户给定的技术参数、设计要求开始。规则获取算法就是从设计参数中挖掘设计知识,从而确定哪种类型的产品最适合用户的要求。该算法不需要任何先验知识。为了将算法应用到实际系统中,必须解决规则表示问题。本文将关系数据库成功地应用于设计规则的表示,使设计出的专家系统推理方便,运行效率高。通过继电器智能设计实例,说明了本方法的应用。

Abstract: Present a new decision rule acquisition algorithm based on rough set and a practical decision rule presentation approach. The product type designed should be decided during concept designing stage, which is usually done from analyzing the specifications and design requirements. The Algorithm of decision rule acquisition is to mine the design rules from the technical parameters, and decide which one type of products is best to the specifications. The presentation of the rules must be solved when the rules are used in Expert Systems. The Relation Database is used for rules presentation. The approach is explained by an example of the relay intelligent designing.
