The notion of interval-valued intuitionistic fuzzy set (IVIFS) was introduced by Atanassov and Gargov as a generalization of an intuitionistic fuzzy set. The fundamental characteristic of IVIFS is that the values of its membership function and non-membership function are intervals rather than exact numbers. Some operators have been proposed for aggregating intuitionistic fuzzy sets. However, it seems that there is little investigation on aggregation techniques for dealing with interval-valued… CONTINUE READING
