基于区间值直觉模糊相容关系,给出了双论域上的区间值直觉模糊粗糙集模型并讨论了其相关性质,为粗糙集的应用提供了新的理论基础与操作手段。最后,通过一个例子阐述了本文提出的区间值直觉模糊粗糙集模型在临床诊断系统中的具体应用。
Based on the interval-valued intuitionistic fuzzy compatible relation,the interval-valued intuitionistic fuzzy rough set model on two universes is presented and the related properties are discussed,from which we obtain new theory and practical approach to apply rough sets.Finally,an example is applied to illustrate the application of the proposed interval-valued intuitionistic fuzzy rough set model in clinical diagnose systems.
