摘要
从动态系统中对象集所对应的属性集出发，结合模糊集理论和变异S-粗集理论提出单向变异S-粗模糊集的概念、结构及其性质，并对此进行了讨论．
Combining attribute sets, which correspond to object sets in the dynamic system, with Fuzzy sets theory and variation s - rough sets theory, this paper presents a research report on the concept, structure and property of s - rough fuzzy sets of one direction variation.
