Abstract

Abstract: Based on k-degree tolerance relation and dominance relation propoled by Wu Peng，et al，this paper discusses the knowledge reduction of the set-valued incomplete information system，and presents the decision theorem，the discernibility matrix，and the specific operation method for the knowledge reduction of the set-valued incomplete information system.

Key words: Rough set, set-valued information system, limited tolerance relation, knowledge reduction

摘要： 基于吴鹏等提出的k度限制相容关系模型，讨论在集值不完备信息系统上的约简，给出集值不完备信息系统属性约简的判定定理和辨识矩阵，得到集值不完备信息系统知识约简的具体操作方法。

关键词: Rough集, 集值信息系统, 限制相容关系, 知识约简
