Abstract: This article is to introduce the concept of a rough soft lattice, which is an extended concept of a rough soft set and a lattice. We study roughness in soft lattices with respect to congruence approximation spaces. Some new rough soft operations are explored. In particular, lower and upper rough soft lattices and some special rough soft lattices are investigated. Finally, we give a decision method based on rough soft lattices.
