摘　　要：基于模糊集理论中贴近度的定义及模糊粗糙集的有关性质 ,讨论了模糊粗糙集 (FR集 )的贴近度 ,进而给出了模糊粗糙集的距离贴近度、最小最大贴近度。In this paper, base on the definition of closeness in fuzzy set theory and some properties of fuzzy rough sets, the closeness of fuzzy rough sets is discussed. The closeness of distance, the least and the greatest closeness, the least average closeness and the closeness in the lattice for fuzzy rough sets are introduced. At the same time, we discuss their properties.

关 键 词：模糊集 粗糙集 模糊粗糙集 贴近度
