A social consensus model with the AHP method under the row geometric mean prioritization method

Abstract

In this research, a social consensus model with the analytic hierarchy process (AHP) under the row geometric mean prioritization method (RGMM) is investigated. To reach social consensus, there is a need for clarification of both individual and social interests. Some consensus models have been proposed for group decision making using the AHP method proposed by Saaty. The purpose of this paper is to extend a group decision model into a social consensus model. One of our goals is to find out the conditions for achieving social consensus with the Pareto optimality, which requires the efficiency of the society as a whole. This gives a solution to social consensus.
