Transportation infrastructures, particularly those supporting intermodal freight, are vulnerable to natural disasters and man-made disasters that could lead to severe service disruptions. These disruptions can drastically degrade the capacity of a transportation mode and consequently have adverse impacts on intermodal freight transport and freight supply chain. To address service disruption, this paper develops a model to reliably route freight in a road-rail intermodal network. Specifically, the model seeks to provide the optimal route via road segments (highway links), rail segments (rail lines), and intermodal terminals for freight when the network is subject to capacity uncertainties. To ensure reliability, the model plans for reduced network link, node, and intermodal terminal capacity. A major contribution of this work is that a framework is provided to allow decision makers to determine the amount of capacity reduction to consider in planning routes to obtain a user-specified reliability level. The proposed methodology is demonstrated using a real-world intermodal network in the Gulf Coast, Southeastern, and Mid-Atlantic regions of the United States. It is found that the total system cost increases with the level of capacity uncertainty and with increased confidence levels for disruptions at links, nodes, and intermodal terminals.

不确定条件下的铁路-铁路多式联运的可靠路由

运输基础设施,特别是那些支持多式联运的基础设施,容易遭受自然灾害和人为灾害的影响,这可能导致严重的服务中断。这些中断会极大地降低运输方式的能力,并因此对联运货运和货运供应链产生不利影响。为了解决服务中断问题,本文开发了一种在路轨联运网络中可靠地运输货物的模型。具体而言,当网络受到容量不确定性影响时,该模型试图通过道路路段(高速公路连接线),铁路路段(铁路线)和联运码头提供最佳货运路线。为了确保可靠性,该模型计划减少网络链接,节点和多式联运终端的容量。这项工作的主要贡献在于,提供了一个框架,使决策者可以确定在规划路线以获得用户指定的可靠性级别时要考虑的容量减少量。使用在美国墨西哥湾沿岸,东南部和中大西洋地区的真实世界联运网络证明了所提出的方法。发现总系统成本随着容量不确定性水平以及对链路,节点和多式联运终端中断的置信度增加而增加。和美国的中大西洋地区。发现总系统成本随着容量不确定性水平以及对链路,节点和多式联运终端中断的置信度增加而增加。和美国的中大西洋地区。发现总系统成本随着容量不确定性水平以及对链路,节点和多式联运终端中断的置信度增加而增加。
