Abstract：Hesitant fuzzy rough set is an expansion of the classical fuzzy rough set. However,the exist hesitant fuzzy rough set model do not take the multi-source information into consideration. To solve such problem,a test-cost-sensitive based multigranula?tion fuzzy rough set model is proposed in this paper. And the theoretical properties of this model are analyzed in detail. The result shows that the model which is proposed in this paper is a powerful expansion with the classical multigranulation fuzzy rough set in re?al world application.
