摘要：

从Dubois模糊粗糙集理论与动态模糊集概念出发,提出了单向S-模糊粗糙集概念和结构,分析了单向S-模糊粗糙集与模糊粗糙集之间的关系,并给出单向S-模糊粗糙集的性质和应用。

关键词: 动态模糊集;模糊元素迁移;Dubois模糊粗糙集;单向S-模糊粗糙集

Abstract:

A one-direction fuzzy rough set is proposed, and its general structure and the concept are given by the theory of Dubois fuzzy rough set and the concept of the dynamic fuzzy set. Then, the relationships between a one-direction S-fuzzy rough set and fuzzy rough set are analyzed, and properties and its application of one-direction S-fuzzy rough set are presented.

Key words: dynamic fuzzy set; fuzzy elementary transfers; Dubois fuzzy rough set; one-direction S-fuzzy rough set
