| Research Abstract |
Our research focuses on the resolution of conflicts theoretically and practically. The multilateral conflict aspects are considered. Our approaches are based on possibility theory, bidding theory, cooperative game theory and graph models.
Fair cost sharing of network maintenance is analyzed. It is shown that the Shapley values of cooperative game theory give a rational resolution of the problem. We give a definition of characteristic function of network structure then define the Shapled values on it. They can be calculated very easily. The idea is applied to the actual situation, maintenance of railway network by the local governments, and we show that theoretical result is similar to the actual situation.
Applying the graph model to the conflict resolution, we propose a new way of policy analysis. It is shown that the important thing about the refinement is limited to the stakeholders' direct interests.
We also consider the bidding problem of the public construction. It is pointed out that under an uncertainty such as ground condition the expected values are not appropriate for both governments and builders. We propose a new bidding system that does not use the expected values as payoffs. Our bidding system is designed by using the second price bidding system.
We formalize the uncertainty of demand by possibility distribution, then propose a new decision models. By our new decision model we can determine the optimal order quantity of the short life cycle goods.
We have proposed several ways of conflict resolutions that can be applied to the actual situations. It is expected that these will be applied to many real conflicts.
