Rough set theory was introduced by Pawlak in 1982 to handle imprecision, vagueness, and uncertainty in data analysis. Our aim is to generalize rough set theory by introducing concepts of β -lower and β -upper approximations which depends on the concept of β -sets. Also, we study some of their basic properties.
