An Analysis of Several Novel Frameworks and Models in the Consensus Reaching Process

Usually, at the beginning of the group decision making (GDM) problem, experts’ opinions may differ substantially. Therefore, the consensus reaching process is often a necessity in GDM, and numerous approaches for modeling the consensus process have been proposed. This paper provides an analysis for several novel consensus frameworks and models, investigated by our group. They are the consensus models with minimum adjustments, the consensus models based on consistency and consensus measures, and the direct consensus framework for GDM with different preference representation structures. The advantages of these consensus frameworks and models are analyzed. Meanwhile, the drawbacks and future researches are discussed.
