(2) It extracts conflicts which should be adusted among decision makers in the group by sharing their viewpoints. (3) It supports negotation processes for resolving cnflicts by using a tradeoff analysis based on sensitivity analysis. (4) It shows each decision maker the degree of agreements and the degree of compromises during the negotiation process. In this abstract, we describe the outline of our system and then show an implementation examplw. The experiental results shows some usefulness of the systemfor supporting negotiation processes by iterative interaction between each decision maker and the system.
