            Abstract : 
The collection of all the rough sets of an approximation space can be made into a 3-valued Lukasiewicz algebra called rough 3-valued Lukasiewcz algebras. BCI-algebras and BCK-algebras are two important classes of logical algebras. In this paper, it is shown that a rough 3-valued Lukasiewicz algebra is a BCI-algebra and a BCK-algebra. The direct relation between rough set theory and BCI-algebras/BCK-algebras is constructed. The definition of rough BCI-algebras and rough BCK-algebras are also given.
