Conflict Analysis Under Incomplete Information and Regional policy

本研究由两部分组成。一是不完全信息冲突分析的理论和方法研究。另一种是不完全信息下的区域市场行为冲突分析研究。第一部分(1)对模糊多属性效用分析的理论背景进行了研究，给出了模糊多属性效用分析的表示定理并给出了严格的证明。另一个研究是关于合作模糊对策的构造。首先，(2)基于特征函数的模糊评价，研究了特征函数形式的协同模糊对策的构造。然后(3)检验了核仁作为多变环境下合作博弈解的鲁棒性。讨论了合作模糊对策的参数规划形式与模糊线性规划形式的相似性。在这些研究中，模糊环境被认为是由于群体决策情境的存在而形成的。第二部分为提高实际应用效率，开发了群体决策模糊效用评价的交互式支持系统。从信息不对称的角度考察了广告对提供地方公共产品的城市形成的影响。作为实证研究，采用区域计量经济模型对神户市进行了模拟分析。

This research was composed of two parts. One is theoretical and methodological studies on conflict analysis with incomplete information. Another one is Studies on regional market behavior with conflict analysis under the incomplete information.Concerning the Part one,(1)investigations on theoretical backgrounds of fuzzy multiattribute utility analysis(FMUF) was performed and provided a representation theorem of FMUF with a rigorous proof. Another study is concerned with construction of cooperative fuzzy game. First of all,(2)construction of cooperative fuzzy game in characteristic function form was examined based on fuzzy evaluation of the characteristic function. Then(3) the robustness of nucleolus as a solution of the cooperative game in changeable environments was examined. The similarity of the parametric programing formation for this purpose to fuzzy linear programing formation for the cooperative fuzzy game was discussed. In these studies, the fuzzy environments were presumed to be formed by the existence of group decision situations.Concerning the Part two, for efficiency in practical use, an interactive support system for the fuzzy utility evaluation in group decision making was developed. The effects of advertising on city formation with the provision of local public goods was also investigated from the point of view of the asymmetry of information. As an empirical study, a simulation analysis using the regional econometric model was performed for the Kobe City.
