| 摘 要： | 文9]在Pawlak近似空间中讨论了粗糙模糊集的构造,本文将在普通近似空间中讨论基于λ-上截集、强λ-上截集,λ-下截集、强λ-下截集,λ-上重截集、强λ-上重截集,λ-下重截集、强λ-下重截集的基于模糊等价关系的粗糙模糊集的构造性质;并以截集的形式定义了近似空间中的上、下近似,然后给出了此新的定义下粗糙模糊集所满足的性质.

| Abstract: | This paper mainly studies the constructive properties of rough fuzzy sets based on some kinds of cutsets under generalized approximation space.It is an extension of paper9],and then another definition of lower approximation and upper approximation is given based on the cutsets,and the corresponding properties is proved based on this new definition. |
