Computer-Assisted Negotiations of Water Resources Conflicts

This paper describes the algorithms within and results obtained using an interactive computer program developed to assist those involved in negotiating agreements among parties having conflicting objectives. This Interactive Computer-Assisted Negotiation Support system (ICANS) can be used during the negotiation process by opposing parties or by a professional mediator. On the basis of information provided to the program, in confidence, by each party, it can help all parties identify feasible alternatives, if any exist, that should be preferred to each party's proposal. If such alternatives do not exist, the program can help parties develop counter proposals. Through a series of iterations in which each party's input data, assumptions, and preferences may change, ICANS can aid each party in their search for a mutually acceptable and preferred agreement. This paper describes the algorithms used for analyzing preferences and for generating alternative feasible agreements. Also presented a re the results of some limited experiments involving water resource system development and use conflicts that illustrate the potential of programs such as ICANS.
