Abstract
Generally, as for the large-scale development, a planning and construction period turns in a long time. And the change of the sense of values happens for this period. Because of this, the plan that is thought to be the most rational at the early stages of a plan often becomes far from the inhabitant's request at the time of the completion. In other words, large-scale development project involves self-contradiction. The occurrence of the conflict between the environment side player and the development side player causes self-contradiction to come out. In this paper, a change of the sense of values and the decline of the disaster consciousness are modeled by the attitude change function.This function consists of the mutual influence models which describes the mutual influence between the players and the oblivion models which describes a change in a time target of the person's oblivion. An analysis by the circulation to take a time shaft into consideration becomes possible by combining the model with the conflict analysis that is focusedon a stability analysis. This model is applied to the problem of Nagara River mouth weir to check the adaptability of themodel, and to do a history analysis.
