摘要: 针对系统具有的模糊、不确定及动态特性,基于直觉模糊集和单向S-粗集理论,提出单向S-粗直觉模糊集,给出它的结构、性质、存在背景和意义解释。分析了单向S-粗直觉模糊集与Pawlak粗集,单向S-粗模糊集以及单向S-粗集等之间的关系。

关键词: 单向S-粗直觉模糊集, 隶属函数, 非隶属函数, 直觉模糊迁移

Abstract: According to the fuzzy,uncertain and dynamical properties of the systems,based on intuitionistic fuzzy sets and one-direction S-rough sets,one-direction S-rough intuitionistic fuzzy sets is proposed.The structure,properties,existing background and meaning explanation of one-direction S-rough intuitionistic fuzzy sets are presented.The relations of one-direction S-rough intuitionistic fuzzy sets,Pawlak rough sets,one-direction S-rough fuzzy sets and one-direction S-rough sets are analyzed.

Key words: one-direction S-rough intuitionistic fuzzy sets, membership function, nonmembership function, intuitionistic fuzzy transfer
