Abstract :
The variable precision covering rough set model is promoted by extending the range of error parameter in this paper. Some properties of the promoted variable precision covering rough set model are discussed. Furthermore, we get some meaningful conclusion by means of researching on the power effect of covering variable precision approximation operators for the promoted variable precision covering rough set model.
