Abstract :
Recently, much attention has been given to the rough set models based on two universes of discourse. And many rough set models on two universes have been developed from different views. In this paper, a novel model, the intuitionistic fuzzy rough set model over two different universes is firstly proposed from the intuitionistic point of view. We study some important properties of approximation operators.
