Abstract: By using the upper and lower approximations and the properties of the multi-granularity rough sets, and combining with fuzzy sets decomposition theorem, the representation and properties of upper and lower approximations of multi-granularity fuzzy rough sets are studied. Based on the upper and lower approximations of fuzzy rough sets, the belief function and the probability function are constructed.

Key words: multigranularity, rough set, fuzzy set, belief function, probability function
