AN ANALYTIC HIERARCHY PROCESS MODEL OF GROUP CONSENSUS
摘要
In group decision making,a certain degree of consensus is necessary to derive a meaningful and valid outcome.This paper proposes a consensus reaching model for a group by using the Analytic Hierarchy Process(AHP).It supports people to improve their group consensus level through an updating of their judgments.In this model,a moderator suggests the most discordant decision maker to update his judgment in each step.The proposed consensus reaching model allows decision makers to accept or reject the suggestion from the moderator.This model ensures that the judgment updating is effective and the final solution will be of acceptable consistency.Finally,a numerical example is given to illustrate the validity of the proposed consensus reaching model.
