在区间直觉模糊近似空间上,利用一对区间直觉模糊蕴涵算子(只夕),定义了蕴涵区间直觉模糊粗糙集的概念,并证明了相应的一些重要性质。刻画了区间直觉模糊关系的自反性,对称性和传递性。
By employing two interval-valued intuitionistic fuzzy implicators and , interval-valued intuitionistic fuzzy rough sets with implicators are first defined in the interval-valued intuitionistic fuzzy approximation space. Properties of interval-valued intuitionistic fuzzy rough sets with implicators are proved. Finally, the reflexivity, symmetry and transi- tivity of interval-valued intuitionistic fuzzy relations are characterized.
