As reaching the maximum consensus degree in the group decision making problems is very important, many consensus reaching processes have been proposed in the literature. An important step within a consensus reaching process is the feedback mechanism, in which the experts involved in the decision problem under consideration are advised to modify their opinions in order to increase the level of consensus achieved. Therefore, many different feedback mechanisms have been proposed in the existing literature. The aim of this study is to present three of them and analyze their strengths and weaknesses. To do so, an illustrative example is provided.
