Title of Thesis: Scheduling Under Uncertainty for a Single-Hub Intermodal Freight System Degree Candidate: Nikola Marković Degree and Year: Master of Science, 2010 Thesis directed by: Paul Schonfeld Professor Department of Civil and Environmental Engineering This thesis addresses the optimization of an intermodal system with freight transfers at a single hub. It investigates the transportation processes and constraints that arise in a system’s recovery after a major disruption during which backlogs have accumulated along the routes. When dealing with the backlogs, the system operator must coordinate the transportation processes and control the inflow of freight to the terminal in order to avoid overloading its storage facilities, which might reduce the throughput of the system. The coordination of transportation processes during the system’s recovery can further improve the overall system performance by reducing the dwell time, increasing vehicle utilization and reducing late delivery penalties. This work focuses on the scheduling problem and develops an approach that would help the

Job Creation Factors for Inland and Near Dock Intermodal Facilities
The major driving forces behind the establishment of intermodal facilities include number of jobs that will be created by the facility, freight performance improvement, and other economic benefits to the region. Job creation is the most tangible benefit that stakeholders use to justify the development of such facilities. This project explores different job creation factors for intermodal facili...
متن کاملAlternative transport network designs and their implications for intermodal transhipment technologies
Six principles for operation of the rail part of intermodal rail freight transport systems are described: direct link, corridor, hub-and-spoke, connected hubs, static routes, and dynamic routes. The first part is a theoretical discussion of the characteristics of the transport network designs. The theory is then applied to intermodal freight transport by analysing how each transport network des...
متن کاملBi-objective optimization of multi-server intermodal hub-location-allocation problem in congested systems: modeling and solution
A new multi-objective intermodal hub-location-allocation problem is modeled in this paper in which both the origin and the destination hub facilities are modeled as an M/M/m queuing system. The problem is being formulated as a constrained bi-objective optimization model to minimize the total costs as well as minimizing the total system time. A small-size problem is solved on the GAMS software t...
متن کاملMinimizing greenhouse gas emissions in intermodal freight transport: an application to rail service design
Freight transport has undesirable effects on the environment. The most prominent of these is greenhouse gas emissions. Intermodal freight transport, where freight is shipped from origin to destination by a sequence of at least two transportation modes, offers the possibility of shifting freight (either partially or in full) from one mode to another in the hope of reducing the greenhouse emissio...
متن کاملRobust uncapacitated multiple allocation hub location problem under demand uncertainty: minimization of cost deviations
The hub location–allocation problem under uncertainty is a real-world task arising in the areas such as public and freight transportation and telecommunication systems. In many applications, the demand is considered as inexact because of the forecasting inaccuracies or human’s unpredictability. This study addresses the robust uncapacitated multiple allocation hub location problem with a set of ...
