Conflict of Interest : None declared

Rough set model with lower and upper approximations based on lattice theory is defined and for the new model some properties are given. Lattice theory plays an important role in rough set theory and fuzzy set theory, so the new rough set model over lattice theory in this paper may be a new tool to study the relationship between fuzzy set theory and rough set theory.
