Abstract: Combining rough sets and soft sets, we apply rough soft sets to BL-algebras. Some new operations of the lower and upper soft approximations are obtained. In particular, rough soft (implicative, positive implicative, fantastic) filters with respect to a filter over BL-algebras are also investigated. In particular, we propose two kinds of decision making methods for rough soft BL-algebras. Finally, the numerical experimentation program is written for given by MATLAB, which supports the above decision making methods.
