Abstract:

We propose an optimization framework for routing rail-truck intermodal shipments when shippers and receivers have access to alternate intermodal terminals. The objective is aiming to minimize the total transport cost and infrastructure improvement cost from the perspective. The decisions include hub capacity improvement, main line transport services designing, the access to alternate intermodal terminals and segments reconstruction. Our analysis indicates that route-selection is driven by customer specified delivery-times. Reduction is possible by using faster trains and negotiating a later delivery-time so that advantageous paths can be taken through. Meanwhile, identification of major intermodal gateways in each region and the high- traffic rail-links in the network can facilitate the improvement of infrastructure system.

Key words: integrated transportation, rail-truck multimodal transportation, network optimization, modeling optimization

摘要:

基于公铁联运模式,构建干支线运输方案设计的混合整数规划模型,揭示了网络基础设施配置与干线运输服务设计间的协调优化关系.对公铁联运网络的枢纽等级配置、干线运输服务设计、货物托运人和收货人对于中转枢纽的选择、货物托运人和收货人对干线运输服务的选择,以及干线区段改造方案等决策进行综合优化.分析表明,收货时间限制成为联运方案选区的关键约束条件.此外,公铁联运中转枢纽节点的能力制约着联运系统的服务能力,瓶颈区段的识别并改进,以及合理的干线差异化等级的运输服务组合能够大幅度降低网络运营成本
