利用吴伟志所定义的两个直觉模糊蕴涵算子I和J,把(I,J)-直觉模糊粗糙集的概念推广到区间直觉模糊集的情形,给出了区间直觉模糊近似空间的概念及(I,J)-区间直觉模糊粗糙集,研究了(I,J)-区间直觉模糊粗糙集的基本性质并推广了张植明等人提出的结论。
By two intuitionistic fuzzy implicators I and J in Wu Weizhi's paper,this paper extends(I,J)-intuitionistic fuzzy rough sets to(I,J)-interval-valued intuitionistic fuzzy rough sets.It defines an interval-valued intuitionistic fuzzy approximation space.It investigates the properties of(I,J)-interval-valued intuitionistic fuzzy rough sets.It generalizes the results in Zhang Zhiming et al's paper.
