摘要
基于文献[1]给出的Pawlak近似空间上的模糊集的粗糙度的概念,把粗糙度的定义推广到模糊T近似空间上,得到了粗糙模糊集的粗糙度,并讨论了它们的性质。
According to the concept of roughness of fuzzy set on Pawlak approximation spaces given in literature[1], the paper extended the roughness to the fuzzy T approximation spaces and got the roughness of rough fuzzy set, and also the properties of the new roughness are discussed.
