background, aim, method, result) max 200 words: The number of zones for unloading goods in the city centre is often small compared to the number of delivery addresses and carriers. The attendant phenomenon is congestion and its subsequent costs. One way to reduce these effects is to implement retail consolidation centres. Some trials have been carried out on urban distribution centres and a few...

We investigate how containerization impacts local economic activity. Containerization is premised on a simple insight: packaging goods for waterborne trade into standardized container makes them dramatically cheaper to move. use novel cost-shifter instrument -- port depth pre-containerization contend with the non-random adoption of by ports. Container ships sit much deeper in water than their p...

This paper discusses optimization of freight train locomotive rescheduling under a disrupted situation in the daily operations in Japan. In the light of the current framework of dispatching processes that passenger railway operators modify the entire timetables, the adjusted timetable is distributed to a freight train operator. We solve the locomotive rescheduling problem for the given adjusted...

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 ...

Integrating passenger and freight flows creates attractive business opportunities because the same transportation needs can be met with fewer vehicles and emissions. This paper seeks an integrated solution for the transportation of passenger and freight simultaneously, so that fewer vehicles are required. The newly introduced problem concerns scheduling a set of vehicles to serve the requests s...

Continuous growth in air cargo deliveries and increasing competition is necessitating freight forwarders to develop innovative solutions to improve performance and reduce costs. This study considers a freight forwarder's operational implementation of alternative access airport policy in a multi-airport region for air cargo transportation. Given a set of heterogeneous air cargo customers, the fo...

In this paper, an integrated Network and Vehicle Routing Optimisation Problem (NVROP) for freight vehicles is proposed. The variables involved in the problem are discrete (link topology, routes for freight vehicles) and continuous (link capacity in term of signal settings). The discrete variables are related to the link direction, lane numbers, lane use and sequence of retailers reached by the ...

We analyse maintenance cost data for Swedish railway infrastructure in relation to traffic volumes and network characteristics, and separate the cost impact from passenger and freight trains. Lines with mixed passenger and freight traffic, and dedicated freight lines are analysed separately using both log-linear and BoxCox regression models. We find that for mixed lines, the Box-Cox specificati...

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 ...
