摘要：
In this paper, the dominance-based rough set approach is introduced into multigranulation environment. Two different dominance-based multigranulation rough sets models: dominance-based optimistic multigranulation rough set and dominance-based pessimistic multigranulation rough set are constructed, respectively. Not only the properties of these two dominance-based multigranulation rough sets are discussed, but also the relationships among dominance-based optimistic multigranulation rough set, dominance-based pessimistic multigranulation rough set and the classical dominance-based rough set are investigated.
