Negotiation Simulation System Based on Fuzzy Decision-Making

Abstract

This paper introduced the simulation system that helps and supports the party concerned when they negotiate to make a decision. The negotiation model is designed to work by modifying the utility function to compromise in the decision making process. The simulation method based on fuzzy decision making is also suggested to find out the solution or the compromising point that would satisfy both sides. In solution of the problems with multi-stage the movement of each negotiator's opinion is taken into consideration in the view of their adherence to the attributes for decision making in order to make concession, and its concepts is based on human behaviors. After several variations of membership functions and rules basic to the fuzzy control are supposed, the sumulation is done to seek out the compromising point and its process. As a concerte example of the simulation, group car buying decision is dealt with for showing its actual process and the results. All the results suggerst that this method is expected to be efficient in searching for a compromising point to avoid an explosin of combinations of solutions available.
