本文旨在通过建立一个混合整数规划公式，为长江沿岸钢铁厂集群提供一个最优的航运计划。该模型考虑了长江上多层次的航运网络，动态的铁矿石价格和运输成本，以及钢铁厂在多个时期的及时需求。通过将提出的模型应用于现实世界的案例，观察到几个有趣的发现，导致进一步有用的管理见解。我们还提出了一种基于动态规划算法的精确解方法来解决这个问题的一个特殊情况。
This paper aims to provide an optimal shipping schedule for steel-manufacturing plants cluster alongside the Yangtze River by developing a mixed integer programming formulation. The model takes into account the multi-layer shipping network on the Yangtze River, the dynamic iron ore price and transportation costs, and the timely demands of steel plants over multiple periods. By applying the proposed model to a real-world case, several interesting findings are observed, leading to further useful managerial insights. We also propose an exact solution approach based on a dynamic programming algorithm to a special case of this problem motivated by real-world practice.
