Modeling Negotiations in Group Decision Support Systems
Group decision making processes are usually characterized by multiple goals and conflicting arguments, brought up by decision makers with different backgrounds and interests. This paper describes a computational model of negotiation and argumentation, by which participants can express their claims and judgements, aiming at informing or convincing. The model is able to handle inconsistent, qualitative and incomplete information in cases where one has to weigh multiple criteria for and against the selection of a certain course of action. It is implemented in Java, the aim being to deploy it on the World Wide Web. The basic objects in our terminology are positions, issues, arguments pro and con, and preference relations. The paper describes procedures for consistency checking, preference aggregation and conclusion of issues under discussion. The proposed model combines concepts from various well-established areas, such as Multiple Criteria Decision Making, nonmonotonic reasoning and cognitive science.
