A Support System for Multilateral Negotiations

A Negotiation Support System (NSS) is developed based on the conceptual framework of the Evolutionary Model for Multilateral Negotiations (EMMN). The EMMN methodology is utilized to identify the most likely outcomes of asymmetric multilateral negotiations, in which each negotiator seeks to reach the most preferable outcome for which he or she can gain enough support from other negotiators. This NSS increases the speed of calculations, as well as avoids the errors typical of manual stability calculations and sensitivity analyses. All stable and feasible negotiation states are identified and illustrated in the output of this NSS, which is, therefore, a valuable aid in practical negotiations.
