Single-Car Routing in Rail Freight Transport

Cars in rail freight service follow prescribed routes from their origin via intermediate shunting yards to their destination. The goal in designing such routes is to reduce the number of trains and their travel distances. Various real-world hard constraints make the problem difficult to formulate and also to solve. We present integer programming formulations for this car routing problem arising...

Improving Resilience of rail-based intermodal Freight Transportation Systems

Title of Document: IMPROVING RESILIENCE OF RAIL-BASED INTERMODAL FREIGHT TRANSPORTATION SYSTEMS Xiaodong Zhang, Doctor of Philosophy, 2013 Directed By: Professor Elise Miller-Hooks, Department of Civil & Environmental Engineering With the increasing natural and human-made disasters, the risk of an event with potential to cause major disruption to our transportation systems and their components ...

Scheduled Service Network Design for Freight Rail Transportation

The paper addresses the scheduled service network design problem for freight rail transportation. The proposed model integrates service selection and scheduling, car classification and blocking, train make up, and routing of time-dependent customer shipments, based on a cyclic three-layer space-time network representation of the associated operations and decisions, their relations and time dime...

Automated Generation and Optimization of Public Railway and Rail Freight Transport Time Tables

Railway traffic now and in future faces ever-growing challenges. On the one hand, infrastructure measures must be planned and in the medium respectively long term corresponding operating programs have to be generated. On the other hand, in the short term economical and political reasons exert increasing influence on the requirements of timetabling as well. Hence, they can hardly be efficiently ...
