The Graph Model for Conflict Resolution constitutes a unique and flexi
ble approach to the representation, analysis, and understanding of str
ategic conflict. This methodology, as implemented in the Decision Supp
ort System GMCR, constitutes a useful tool for negotiation support. Be
cause GMCR includes efficient algorithms for calculating the stability
of states, it encourages extensive comparisons of the consequences of
different models of negotiators' decision making. GMCR also facilitat
es modifications to the way in which the conflict is represented, enco
uraging sensitivity and what-if analyses. The applicability of GMCR to
negotiations is discussed in general, and in the context of a specifi
c case study in environmental conflict resolution.
