“…An important question here is the level of agreement or consensus reached among the group of decision makers before obtaining the solution. Many results of psychological investigations and also a real life experience clearly show that obtaining a solution without a sufficient agreement among the decision makers is not reasonable as it may be not accepted, and can lead to a solution with no chance for its practical implementation or even prevent the survival of the group in the long time period [23]. Therefore, it is desirable that the decision makers carry out a consensus process [5,51], in which all of them discuss their opinions in order to arrive at consensus.…”

Abstract. Group decision making is part of every organizational life. It is a type of participatory process in which multiple decision makers acting collectively, analyze problems, consider and evaluate several alternatives, and select from among the alternatives a solution. In such a situation, an important issue is the level of agreement or consensus achieved among the group of decision makers before obtaining the solution. In the beginning, consensus was meant as a full and unanimous agreement. Regrettably, this stringent concept of consensus in many cases is a utopia. As a result, and from a pragmatic point of view, it makes more sense to speak about a degree of consensus and, here, the theory of fuzzy sets has delivered new tools for the analysis of such imprecise phenomena like consensus. Given the significance of reaching an accepted solution by all the decision makers, consensus is a major aim of group decision making problems and, in such a way, it has obtained a great attention in the literature. However, there still exist several dares which have to be tackled by the researchers. The purpose of this paper is to bring out several issues that represent challenges that have to be faced.
