| Outline of Final Research Achievements |
We dealt with a two-level production and transportation planning problem for supply chain management between a distributor and a manufacturer, and formulated the production planning problem from the perspective of DEA, taking into account uncertainty of the manufacturer's production technology information. A two-stage supply chain model for facility opening and transportation was formulated to maximize uncertain profits. In order to deal with disruptions in the supply chain, we proposed a model taking into account the risk attitude of the manager. To maximize the profit in a multiperiod linear production problem in which multiple firms pool their uncertain resources, we formulated a cooperative game taking into account the risk attitudes of players, and furthermore extended it to a two-objective cooperative game for the profit maximization and the reduction of greenhouse gas emissions.

経団連は民間と官，あるいは企業間の協調の重要性を指摘している．一方，近年の度重なる自然災害を経て，災害に対する事業の持続可能性は喫緊の課題である．このような背景のもと，本研究では関連する組織や企業などの経済主体が独自の戦略に従いながらも，互いに協力することによって，収益を向上させるだけでなく，経済主体の経営基盤の更なる健全化や頑健化を考える．経済主体間での協調的運営をモデル化するが，必ずしも経済主体が完全に協力し，最終的に経済主体を統合することはないと考える．そのため，各経済主体の独自の活動と経済主体の協調的運営を同時に考慮するモデル化とその計算手法をあらたに開発した．
