摘要
基于变异S-粗集和相容关系,提出了广义双向变异S-粗集,给出了它的变异结构,并对广义双向变异S-粗集的有关性质进行了讨论。广义双向变异S-粗集为研究具有相容关系的动态系统提供了新的途径和方法。
Based on the variation singular rough sets and the correlation, this paper proposes the generalized two-direction variation singular rough sets and introduces the variation structure. And it further discusses the features of generalized two-direction variation singular rough sets. Generalized two-direction variation singular rough sets provide new approaches to the research on the dynamic system with correlation.
