The strength of coalition in a dispersed decision support system with negotiations
2016, European Journal of Operational ResearchCitation Excerpt :In the paper Ntouskas and Polemi (2012), a collaborative decision aid process that is based on multi-criteria decision aid approaches for risk management that aims to categorize security threats is presented. The system JUDGES, which uses a graphical tool in order to discover the consensus and conflicts among individual preferences, is proposed in the paper Colson and Mareschal (1994). The multi-criteria group decision support tool PLEXYS, which uses a 10-level scale for the evaluation of alternatives based on the criteria, is presented in the paper Dennis, George, Jessup, Nunamaker, and Vogel (1988).

2001, European Journal of Operational ResearchCitation Excerpt :After describing the distinctive way of distributed decision making in Japanese organisations they develop a formal mathematical model, based in part in MCDM notions, to help the co-ordinator facilitate the group decision process. Colson and Mareschal (1994) introduced JUDGES, a descriptive GDSS for the co-operative ranking of alternatives. The system uses graphical representations to provide the decision makers with a clear view of their consensus and disagreements with the help of four Group (Visual) Decision Aids (GDAs) components.
