摘要
在经典的覆盖近似空间中,定义了区间直觉模糊概念的粗糙近似。通过区间直觉模糊覆盖概念,给出了一种基于区间直觉模糊覆盖的区间直觉模糊粗糙集模型。讨论了两种模型的一些相关性质。
Rough approximation of an interval-valued intuitionistic fuzzy set is established based on a crisp covering approxima- tion space. The interval-valued intuitionistic fuzzy rough set models based on a interval-valued intuitionistic fuzzy covering are presented by the concept of interval-valued intuitionistic fuzzy covering. Some properties of the interval-valued intuitionistic fuzzy rough sets based on covering are discussed.
