Abstract :
The paper mainly supplements the definition of Granular sets which was proposed by predecessors. If let X be given, X is the subset of one or more granules and each granule is not the subset of X on the tolerance relation of Gr, we define some concepts of lower and upper approximation of X, and discuss its properties.
