摘要
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 Lambda(beta)-lower and Lambda(beta)-upper approximations which depends on the concept of Lambda(beta)-sets. Also, we study some of their basic properties.
