Abstract
Recently, from the view point of financial readjustment, both the Central and the Local Government want to reexamine the construction system of Infrastructure. Now, many of the businessman want to make a new allocation system that is recognized by the society that is equity and fair. So, we proposed the Formed Agreement cost-allocation Model for the project composed several sections. This allocation system has a special function that can accommodate the participation's opinion. In this paper, we analysis the elemental factor and try to Game-theoretic analysis to understand the quality of the solution on this proposed cost-allocation model. To illustrate the property of this model, We picked up the case study, the access to the Hibiki New Port in Kitakyushu City, that is recognized as an international leading port by the Ministry of Transport. And we want to construct the Connecting Bridge by use of this model on the point of P. F. I.(Private Finance Infrastructure).
