Abstract: 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.

Key words: interval-valued intuitionistic fuzzy rough sets, interval-valued intuitionistic fuzzy sets, interval-valued intuitionistic fuzzy implicators, rough sets

摘要: 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。
