From cognitive models to multiple decision makers support systems

International audienceWe present in this paper a new approach for building distributed decision supportsystems. Multiple decision makers support systems are devoted to assist setting aconsensus while taking into account all aspects related to the distributed nature ofthe processes. This approach is based on the integration of the individual cognitivemodels of the decision makers of the team and on the modeling of the dynamics ofindividual decisions when being interleaved. Our model allows to detect and pre-vent extremal group behaviors and to identify the right information transfers to beset among decision makers. This model has been tested in a realistic applicationframework concerning decision making in Maritime Surveillance where several oper-ators have to converge towards a unique decision in limited time. We conclude withproposing the main elements of a design methodology for decision makers supportsystems based on the proposed approach
