Abstract

In this paper, we generalized the notions of Pawlak’s rough set theory to a topological model where the set approximations are defined using the topological notion c-open sets. Also, we study some of their basic properties of Pawlak’s rough set model. Moreover, several important measures, related to the new model, such as accuracy measure and quality of approximation are presented.
