摘要
在一般等价关系下,给出单向直觉模糊S-集合、双向直觉模糊S-集合的概念,利用这些概念,提出直觉模糊S-粗集,给出直觉模糊S-粗集的数学结构和有关结论,对有关性质进行了讨论。直觉模糊S-粗集为研究动态信息系统中大量的不确定性问题提供了新的途径和方法。
Concepts of one direction Intuitionistic Fuzzy S-set and two direction Intuitionistic Fuzzy S-sets under commonly equivalent relation are presented, using these concepts, Intuitionistic Fuzzy S-Rough sets are put forward, the mathematics structure and correlative conclusion of Intuitionistic Fuzzy S-Rough sets are presented, and a discussion be made on the correlative characters. The new avenue and method for research large numbers of indeterminate problems in dynamical information systems are offered by Intuitionistic Fuzzy S-Rough sets.
