| Abstract: | The extension of rough set is a hot research direction in rough set theory. The aim of this paper is to present a new extension of rough set model over two different universes which is a new fuzzy rough set on two universes based on a fuzzy compatible relation. The low and upper approximation of a fuzzy set are defined. Moreover， several properties of this rough set model are also investigated. |
