| Abstract: | Variable precision rough set model based on k-equivalent degree tolerance relation is proposed in this paper, and it is a spread that variable precision rough set model in incomplete information system. Its upper and down approximation, negative domain, approximation quality and rough measure are defined, and its properties of upper and down approximation is discussed detailedly. Finally, a real example analysis this model the validity of the application in the information processing. |
