Interval Ordered Rough Set Model Based on Possible Degree Dominance Relation
Abstract：To sovle the deficiencies of five dominance relations in interval ordered systems, a new dominance relation-α-possible degree dominance relation is proposed. The basic properties of α-possible degree dominance relation and the relationships with other dominance relation are analysed. Furthermore, an extended rough set based on α-possible degree dominance relation is defined. The example shows that:by the variety the value of a to adjust the degree of dominance, α-possible degree dominance relation can overcome the deficiencies of former dominance relation in in interval ordered systems.
