• ON SEMI ROUGH SETS

R. PANDURANGA RAO*

Abstract


This present research article introduces semi Rough sets by using Rough membership function. Some interesting properties of semi Rough sets and Rough membership functions are studied. A Rough membership function was introduced by Zdzislaw Pawlak together with Skowron [4] in 1991 and it is used to generate semi Rough sets in this work in a finite universe set. Some of their properties are discussed in this context.
