Abstract

In this paper, based on the fuzzy number intuitionistic fuzzy hybrid geometric (FIFHG) operator and the fuzzy number intuitionistic fuzzy weighted geometric (FIFWG) operator, we investigate the group decision making problems in which all the information provided by the decisionmakers is presented as fuzzy number intuitionistic fuzzy decision matrices where each of the elements is characterized by fuzzy number intuitionistic fuzzy numbers, and the information about attribute weights is partially known. An illustrative example is given to verify the developed approach.
