模糊集方法在粗糙集研究中的一些应用

Applications of Fuzzy Method in Studies of Rough Set Theory

粗糙集理论的创始人Z.Pawlak曾经得出一个结论:“粗糙集是泛化的模糊集;”通过粗糙隶属函数把粗糙集理论与模糊集联系起来,建立了一种粗糙集理论与模糊理论的关系。

The initiator of rough set reaches such a conclusion that ＂rough set is a extensive form fuzzy set＂. In this paper ,we combine the fuzzy set theory with rough set theory by rough membership function and establish a relation between them.
