Applications of rough soft sets in BCI-algebras and decision making

Rough sets and soft sets are important tools to deal with uncertainties. Combining rough sets and soft sets, we apply rough soft set theory to BCI-algebras. Some basic operations of the lower and upper soft approximations are discussed. Some kinds of rough soft ideals of BCI-algebras are also obtained. Finally, two kinds of decision making methods for rough soft BCI-algebras are investigated.
