Fuzzy sets and its extensions are widely used to determine membership of an element using different functions to decrease the effect of uncertainty. In this paper, intuitionistic fuzzy Z-numbers that are a new extension of fuzzy sets are proposed for the first time. First, fuzzy Z-numbers and intuitionistic fuzzy numbers are determined as preliminaries. Then definitions and defuzzification of intuitionistic fuzzy Z-numbers are proposed.
