摘要
在S-粗集的基础上,给出单元素迁移的定义,讨论了单元素迁移对粗集结构的影响,并给出了相关定理;用单元素迁移解释S-粗集的动态过程,给出了S-粗集的动态结构特征.
Based on S-rough set, the defirfifion of single element transfer is given. Its influence on the structure of rough set is discussed, and its correlative theorem is presented. The single element transfer is used to explain the dynamic process of S-rough set. The dynamic structure characteristic of S-rough set is also given.
