| Authors: | WU Yan-hua LI Ke-dian |
| Abstract: | This paper combines interval-valued intuitionistic fuzzy sets and rough sets.It studies rougheness in interval-valued intuitionistic fuzzy sets and proposes one kind of interval-valued intuitionistie fuzzy-rough sets models under the equivalence relation in crisp sets.That extends the classical rough set defined by Pawlak. |
