Modeling the Role of a Coordinator as a Medium of Communication in 2-Player Conflicts

This paper discusses the role of a coordinator in the 2-player conflict where the information on players' preference is incomplete. It is assumed that the coordinator has a priori prospect of feasible alternatives. First, the method of the graph model for conflict resolution (GMCR) is extended to apply to this conflict with incomplete information, and the coordination system for the conflict with incomplete information is proposed. The process operated by the coordinator uses Extended Robustness Analysis that specifies the critical conditions for the stability and Pareto efficiency of an alternative. Finally, the methodology is applied to the conflict between hydropower generation and environmental interests.
