Abstract :
Aiming at a special incomplete information system, this paper proposes a novel rough set model to deal with it. Compared with other systems, this kind of incomplete system has the value of ldquonotrdquo. After analyzed related methods for incomplete information system, this paper proposes one special relation based on CWA and OWA, which can reflect the real situation between objects.
