| Abstract: | A new variable precision tolerance relation is defined and the induced maximal variable precision tolerance classes in interval valued information system are studied,this paper proposes the rough set model based on the maximal variable precision tolerance classes in interval-valued fuzzy objective information systems.Furthermore,the approaches to decision rules acquisition based on membership function are discussed and finally an example illustrates that the approaches are valid. |
