Wu, Yanhua; Li, Kedian Cut set of interval-valued intuitionistic fuzzy sets. (Chinese. English summary) Zbl 1240.03035 J. Hainan Norm. Univ., Nat. Sci. 23, No. 3, 249-252, 273 (2010). Summary: In this paper, firstly, the concepts of cut set of interval-valued intuitionistic fuzzy sets and interval-valued intuitionistic nested set are proposed. Secondly, some properties of cut sets of interval-valued intuitionistic fuzzy sets are discussed. Finally, a decomposition theorem and a representation theorem of interval-valued intuitionistic fuzzy sets are given.
