An alternative calculation of the consensus degree in group decision making problems Moral Ávila, María José Del Tapia García, Juan Miguel Herrera Viedma, Enrique Group decision making Fuzzy preferences Consensus Decision support rules Distance functions Mean absolute deviation In a problem of group decision-making it is desirable to obtain a solution with the highest possible degree of agreement – consensus- among the participants. For this aim, it is necessary to have tools that facilitate the calculation of the degree of consensus in a reliable way. This study proposes a consensus index based on a statistical measure of variability of the preferences expressed by the experts in a group decision-making process and performs a specific comparative study between this index and several known consensus measures. The analysis shows that in this specific situation the proposed measure behaves in a similar way to the previous ones and it could play their role in a process of decision making in group. 2022-11-15T12:23:30Z 2022-11-15T12:23:30Z 2017-12-12 info:eu-repo/semantics/conferenceObject M.J. del Moral...
