| Abstract: | In order to describe the closeness of two rough sets, the concept of the close-degree of rough sets is proposed. The basic properties of the close-degree of rough sets are given. According to some kinds of concrete forms of the close-degree in fuzzy sets, the close-degree of distance, the greatest and the least close-degree, the least average close-degree, and the lattice close-degree of rough sets are defined. |
