| Outline of Final Research Achievements |
A mathematical optimization model for ship routing to minimize fuel consumption was developed, and a computational algorithms to derive its solution was developed. In doing so, we developed a framework incorporate a nonlinear fuel consumption model to accommodate various ship types with different fuel consumption characteristics. Furthermore, we have developed a method to integrate this ship routing method with a ship scheduling model to realize efficient operation of the entire fleet. This makes it possible to operate each vessel in the fleet efficiently and reduce the environmental impact of individual voyages at the same time.

海上での物資輸送における重要な意思決定として，船舶スケジューリングと航路計画が挙げられる．これらの問題は，海上で物資を輸送する複数の船舶を効率的に運用するためのものである．このスケジューリング・計画として良いものができれば，船舶運航による環境負荷を低減できると同時に，船隊として輸送能力を高く保つことができる。本研究では，数理最適化モデルを用いてこのための方法を開発した．
