Abstract
Systems methodologies to model third-party intervention in international conflicts are developed within the framework of the graph model for conflict resolution (GMCR). An inverse GMCR is introduced to utilize the GMCR as a negotiation tool by altering the procedure of the original framework. The methodologies presented give a better understanding of how decision makers (DMs) can be motivated to undertake certain actions within the conflict. Moreover, the inverse GMCR tackles the problem of specifying which preferences for DMs lead to a particular resolution, thereby making it easier for a mediator or other third party to influence the course of the conflict. The methodologies are applied to a real-world dispute, a complex water conflict in the Middle East.
