摘要：
In order to improve the reasoning ability of Rough Sets, this paper generalizes the Pawlark's rough set model to the fuzzy environment. Fuzzy indiscernibility relation is proposed in this paper to replace Pawlark's underlining indiscernibility relation. A number of fundemental concepts of Pawlark's rough set theory such as the kernel and reduct are extended. Furthermore, this paper proposes the fuzzy discernibility matrix. Based on this matrix, a fast and simple approach to obtaining the fuzzy kernel and reduct is given.
