| Abstract: |
| Firstly, this paper defines the support function of the universes, with which the approximation operators of the generalized multi granulation fuzzy rough set is defined, and then generalized multi granulation fuzzy rough set based on two universes model is constructed. In addition, the properties of the approximation operators are discussed. |
| Key words: Rough set multi granulation two universes |
