本文研究了具有铁路和公路两种运输方式的汽车配送网络。由于交货期影响昂贵铁路车辆的周转率，而运量对从工厂到铁路匝道的总交货期有很大影响，因此本文考虑了铁路成本结构中的数量折扣。本文提出了一种基于整数线性规划（ILP）的业务方案，通过模式和匝道选择决策使总配送成本最小化。基于随机创建实例的数值实验表明，该方法得到的解明显优于实际使用的模拟人工协商过程的结果。这两种方案导致的结果在向铁路支付方面没有统计上的差异。
This paper studies an automotive distribution network with two transportation modes: railway and highway. Because lead-time influences the turnaround rate of expensive railcars and volume has a large impact on the total lead-time from a plant to a railway ramp, the paper considers quantity discounts in railway cost structures. This paper proposes a business scheme based on an integer linear program (ILP) to minimize the total distribution costs by making mode and ramp selection decisions. The numerical experiments based on randomly created instances show that the solutions obtained from the ILP significantly outperform the results of the simulated manual negotiation process used in practice. The two schemes lead to results that are not statistically different in payments to railways.
