Abstract The existing hesitant fuzzy rough set model does not take the multi-source information into account. To solve this problem, an optimistic strategy based multigranulation hesitant fuzzy rough set model and a pessimistic strategy based multigranulation hesitant fuzzy rough set model are proposed, respectively. The properties of the two models are shown. Finally, the approximate sets under optimistic version and pessimistic version are analyzed by an example of a multi-source information system.

Key words： Hesitant Fuzzy Set Multigranulation Optimistic Pessimistic Rough set
