摘要
在文献[5]提出单向S-模糊集的基础上,给出映射单向S-粗模糊集概念,映射诱导的等价关系的概念;讨论了映射单向S-粗模糊集的性质。得出单向S-粗模糊集是映射单向S-粗模糊集的特例,映射单向S-粗模糊集是粗集理论的一个新的研究方向。
On the basis of one-direction S-rough fuzzy set introduced in the bibliography [5],this paper defines one-direction S- rough fuzzy set of mapping and mapping equivalence relation.The characteristics about one-direction S-rough set of mapping are discussed.One-direction S-rough fuzzy set is the special case of mapping one-direction S-rough sets and mapping one-direction S-rough fuzzy set is the general form of one direction S-rough fuzzy set.
