Abstract

 

In this paper, different types of interval cut-set of interval-valued intuitionistic fuzzy sets (IVIFSs), complement of these cut-sets are defined. Some properties of those cut-set of IVIFSs are investigated. Also three decomposition theorems of IVIFSs are defined. These works can also be used in setting up the basic theory of IVIFSs.

 

Key words:  Interval-valued intuitionistic fuzzy sets, interval cut-set on interval-valued intuitionistic fuzzy sets, decomposition theorem.
