| Abstract: | Aiming at interval-valued information system,a new dominance relation is presented,then upper and low approximation sets of this system are constructed which are based on this dominance relation.Attribute reduction of interval-valued information system is displayed with discernibility matrix.An example illustrates that this method is simple and easy. |

| Keywords: | rough set interval-valued information system dominance relation
