Abstract: In this article we propose to analyse the extent of agreement in a group of experts employing intuitionistic fuzzy sets. Concept of distances between intuitionistic fuzzy preferences is our main tool to evaluate how far the group is from full agreement (consensus in a traditional sense). Next, we propose to evaluate if it is possible for a considered group to come closer to the state of consensus. Entropy is the measure which makes it possible to say how strong are the preferences of experts.
Keywords: Group agreement (distance from consensus), Intuitionistic fuzzy sets, Intuitionistic fuzzy preference relation, Intuitionistic fuzzy entropy
