An extension of soft rough fuzzy sets

Ismat Beg, Tabasam Rashid

Abstract


This paper introduces a novel extension of soft rough fuzzy set so-called modified soft rough fuzzy set model in which new lower and upper approximation operators are presented together their related properties that are also investigated. Eventually it is shown that these new models of approximations are finer than previous ones developed by using soft rough fuzzy sets. 


Keywords
