Situations of distributed decision making are usually characterized by the existence of different points of view between decision makers (DMs), and by different temporal dynamics within the system, which reinforces importance of studies on information data flows between DMs, and founds usual classical DDSS approaches. We propose here not to limit the analyse of the situation (and consequently the role of the DDSS) to information flows, but to integrate cognitive modelling of each DM, and to use these latter for better analysing relevant information, in order to control it, within the flows exchanged in the system. Our approach relies on a realistic application framework concerning decision making in Maritime Patrol.
