Abstract :
On the basis of studying the limitations of the basic rough set model we presented a general rough set model, which is based on a family set of tolerance relations instead of equivalence relations between objects. In this model, we studied both difference and tolerance between objects, and the model inherits most of the characteristics of the basic model of rough set; and it also has a better effect of approximation classification. And they can be further used to illustrate the relationships between objects in various real applications.
