MCDA and preference disaggregation in group decision support systemsMCDA and preference disaggregation in group decision support systems Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-032001enWithin the frame of decision aid literature, group decision making has drawn the attention of researchers from a wide spectrum of disciplines. Group Decision Support Systems (GDSS) can play a critical role, in decision situations with multiple individuals, each having his/her own private point of view on the handling of the decision problem. In such an environment, the conflict between the members of the group is not a seldom situation. Multiple criteria decision aid (MCDA) methods can be proven as invaluable tools in handling such interpersonal conflicts where the aim is to achieve consensus between the group members or at least reduce the amount of conflict among participating individuals. This paper reviews some of the past approaches in the multiple criteria–multiple decision makers context.http://creativecommons.org/licenses/by/4.0/European Journal of Operational Research 2130414-429 Matsatsinis Nikolaos Ματσατσινης Νικολαος Samaras Andreas Σαμαρας Ανδρεας Elsevier Business--Information storage and retrieval systems information storage and retrieval systems business business information storage and retrieval systems
