摘要:

在高铁快捷货运的实践中,需求不确定性及货运节点的不合理设置大大提高了高铁速运的成本。本文综合考虑枢纽建设、改造的经济性和现有高铁网络运营情况,在轴辐式网络框架下,利用分布鲁棒优化方法考虑需求不确定性,最终将高铁快捷货物运输网络优化模型重构成一个混合整数二次锥规划问题。由于非线性混合整数规划较难求解,本文提出了相应的外逼近(outer approximation, OA)算法。数值实验结果表明,OA算法能够有效地提升求解效率。此外,本文提出的分布鲁棒模型能够在现行高铁网络中获得更具稳定性的枢纽选址结果,提高了高铁货运网络的抗风险能力以及远期运营效益,为高铁快运网络布局规划的枢纽选址工作提供了一定的参考价值。

Abstract:

IIn the practice of China Railway High-speed(CRH) Express, the uncertainty of supply and demand and the unreasonable setting of freight nodes greatly increase the total cost of CRH Express transportation. In this paper, the economy of hub construction and transformation and the operation of the existing high-speed rail network are comprehensively considered. Within the framework of a hub-and-spoke network, a distributionally robust optimization approach is employed to account for demand uncertainty. Furthermore, the optimization model is formulated as a mixed-integer second-order cone programming problem. Because of the low efficiency of solving the nonlinear mixed integer programming directly, the outer approximation (OA) algorithm is introduced. Numerical experiment results show that OA algorithm can effectively improve the solving efficiency. The simulation results demonstrate that the distriutionally robust model achieves a more stable network system, improving both the reliability and operational efficiency of high-speed rail freight network, which provides valuable managerial insights for the hub location planning in the CRH Express network.

Key words: high-speed rail express network optimization, distriutionally robust optimization, hub-and-spoke network location model, outer approximation algorithm
