| Research Abstract |
In this research, we dealt with decision making problems with multiple decision makers, in which parameters of the problems cannot be explicitly defined or consistency of the decision makers cannot always be assumed. To find an outcome better for a particular decision maker, we examined the decision making problems from the point of view that we give the decision maker some advice on how to make a decision. By introducing the preference and some belief of the decision maker and estimating choice of strategies of the other decision makers, we examined strategies which should be selected by the decision maker. To do so, we formulated some mathematical programming problems and developed computational methods for obtaining optimal solutions to the problems. The research program consisted of the following four parts :
1. We dealt with hierarchal decision making problems and examined rational strategies in the problems.
2. We developed decision support systems based on the proposed models.
3. We applied the decision support systems to real world problems.
4. We investigated types of societies in which a certain norm such as the collective rationality holds by using agent-based artificial society models.
We have published a part of the results of the above research program in international journals of the related fields and have also presented some papers in international conferences in 2001-2002. Moreover we intend to contribute some papers to domestic and international journals, and the related research works that we have been continuing presented in the book entitled "Fuzzy and Multiobjective Games for Conflict Resolution" as is shown in the References of this report.
