非線形計画法を用いたモーダルシフトによる環境改善の-考察

抄録

This study discusses a conversion problem from car into ship and/or train transportation inorder to reduce pollutant loads from the two viewpoints; one is money, the other is non-money. While the first money viewpoint has been considered by some researchers, the second non-money viewpoint is newly introduced in this study and will play much important roles in pollution problems in the near future. The proposed conversion problem is transformed into an optimization one to determine share retio of car, ship and train vehicles by non-linear programming method based on modal-shift scheme.The derived share retio of transportation vehicles achieves a resonable environmental improvement.
