Abstract :
In order to make decision from complex information system, a new rough set model based on partial-similarity relation is built by constructive method. In this paper, partial similarity relation is presented. The connection between partial similarity relation and similarity relation is studied. Then, a new rough set, partial-similarity rough set, is constructed and some correlative concepts are introduced. Also, properties of the new rough set model are studied from the two views: rough set approximation operators and partial limitation.
