摘要
知识约简是粗糙集理论的核心问题之一。讨论了具有Fuzzy决策的信息系统的知识约简问题。给出了知识约简的几种定义、相应的知识约简的判定定理和可辨识属性矩阵,从而为具有Fuzzy决策的信息系统的知识约简的计算提供了具体方法。
Knowlwdge reduction is one of the main problems in the study of rough set theory. In this paper, definitions of reduction in information systems with fuzzy decisions are introduced. The judgement theorems and discernibility matrices with respect to these types of reduction are obtained, from which methods of knowledge reduction in fuzzy decision information systems can be derived.
