Abstract
Generalized Ziarkopsilas variable precision rough set model and generalized rough fuzzy set model are introduced and the drawbacks of them are found. Based on support relative error ratio and error parameter beta ( 0 les beta < 0.5 ) , the generalized variable precision rough fuzzy set model is proposed. The basic properties of lower and upper approximation operators are investigated. The relation of between this model and other rough set models is analyzed in detail.
