Extension of Rough Set Model under Dominance Relation Based on Set-Pair Analysis

摘要：

In incomplete information systems, the rough set model based on dominance relation has some limitations. In this paper, by means of set-pair analysis we will define the set-pair (α,β) -dominance relation for incomplete information systems, propose a rough set model based on set-pair (α,β)-dominance relation to extend the classical rough set theory, and then present a corresponding attribute algorithm. By an example, it is verified that this model is more feasible and effective than the model based on dominance relation in practice.
