| Outline of Final Research Achievements |
We consider a cooperative production planning model where some of the resources owned by multiple firms are pooling and they can use these resources by each other. All the firms are cooperative in the sense of sharing the resources, but they are noncooperative because they independently make their own decisions to maximize their own profits. We formulate a two-stage model with stochastic demands, and propose a computational method for obtaining a Nash equilibrium point under the assumption that the total profit at the second stage is allocated to all the firms by using a core allocation which is a stable solution concept in cooperative game theory.

| Academic Significance and Societal Importance of the Research Achievements |
近年頻発する大規模な災害にも対応しうるように，特定の製造業界では，各社独自の事業継続計画の策定から，業界全体で危機に取り組めるような体制を整え，業界全体での事業継続計画の策定を目指している．本研究課題の成果は，このような要求に対応できるような協調的サプライチェーン構築に資するものであり，事業の継続性，システム運営の効率化，サプライチェーン全体の利益の増加あるいはコストの削減等に対する数量的評価に対して，提案するモデルの効果が期待できる．
