Abstract

Multimodal integration can effectively address the challenges of sustainable urban freight, and utilizing a metro-based passenger and freight cotransportation system during off-peak hours represents a viable interim solution before establishing an underground logistics system. Given the constraints related to passenger carriage crowding, this study explores an integrated optimization problem that involves capacity allocation and timetable rescheduling for metro-based passenger and freight cotransportation lines under a train-shared mode. The final decision-making includes determining the size of the train fleet, the train timetable, the arrangement of carriages, and the assignment of freight flow. Since demand arrival rates are considered continuous functions over time, this integrated problem is formulated as a nonlinear mixed-integer model. To address the most complex aspects of the model, a gradient-based heuristic algorithm is proposed. Finally, numerical examples using real metro lines are provided to test the applicability and effectiveness of the proposed model and algorithm, and the impact of metro-based freight on passenger experience is also analyzed.

综合优化地铁客货联运的运力分配和时刻表重新安排

多式联运可有效解决可持续城市货运的挑战，而在建立地下物流系统之前，在非高峰时段利用地铁客货联运系统是一个可行的临时解决方案。考虑到与客运车厢拥挤相关的制约因素，本研究探讨了一个综合优化问题，涉及列车共享模式下地铁客货联运线路的运力分配和时刻表重新安排。最终决策包括确定列车编组规模、列车时刻表、车厢安排和货运流量分配。由于需求到达率被认为是随时间变化的连续函数，因此这一综合问题被表述为一个非线性混合整数模型。为了解决模型中最复杂的问题，提出了一种基于梯度的启发式算法。最后，还提供了使用实际地铁线路的数值示例，以测试所提模型和算法的适用性和有效性，并分析了地铁货运对乘客体验的影响。
