Background: Road transport companies utilize transport capacities as fixed compositions of tractors and semi-trailers, while the possibility of exchanging semi-trailers is considered ad hoc, after some unforeseen circumstances emerge on the route. Such an approach is a limiting factor in...

Die Dissertation beschäftigt sich mit der Entwicklung der taktischen Optimierungsmodelle für globale und regionale Containersteuerung. Die Modelle beinhalten gemeinsame, spezifische Durchschnittsparameter, die den Zusammenhang zwischen den Steuerungsebenen ermöglichen. Die Probleme werden als...

Transportation engineers are taught that as demand for travel goes up, this decreases not only speed but also the capacity of the road system, a phenomenon known as hypercongestion. We revisit this idea. There is no question that road systems experience periods in which capacity falls. However,...

PurposeEmpty container trucks may cause a deficit in transport capacity and contribute to congestion and emissions in the port territory. Reengineering of the container truck hauling process to introduce truck-sharing arrangements using the truck appointment system has the potential of reducing...

For a commercially operating railway company, providing a high level of service for the passengers is of utmost importance. The latter requires a high punctuality of the trains and an adequate rolling stock capacity. Unfortunately, the latter is currently (2002) one of the bottlenecks in the...

The provision of third-party access to rail infrastructure in WA's Pilbara region has been a contentious issue over the past decade. The most recent endeavour proposed by the State Government involves a haulage regime, whereby incumbents would be required to haul the wagons of third parties...

In this paper we introduce robust versions of the classical static and dynamic single leg seat allocation models as analyzed by Wollmer, and Lautenbacher and Stidham, respectively. These robust models take into account the inaccurate estimates of the underlying probability distributions. As...

Based on two strands of theoretical research, this paper provides new evidence on how fares are jointly affected by in-flight seat availability and purchasing date. As capacity-driven theories predict, it emerges that fares monotonically and substantially increase with the flights occupancy...

Die Liberalisierung des Luftverkehrs in Europa (aber auch weltweit) hatte das Ziel, über eine Intensivierung des Wettbewerbs, Effizienzgewinne im System Luftverkehr zu realisieren. Ergebnis der Liberalisierung war es jedoch, dass sich lediglich auf wenigen Hauptstrecken Wettbewerb...

We describe an algorithmic approach to determine an efficient railway rolling stock circulation ona single line or on a set of interacting lines. Given the timetable and the passengers? seatdemand, we develop a branch-and-price algorithm that results in an allocation of rolling stockmaterial to...

Especially in the short-term, prices in natural gas markets are not exclusively determined by overall supply and demand, but also by the availability of the transport infrastructure. If transportation capacity is scarce, prices may form in (local) residual markets and can differ regionally. If...

This paper considers the use of ‘long-run cost functions’ for congested networks in solving second-best network problems, in which capacity and tolls are instruments. We derive analytical results both for general cost and demand functions and for specific functional forms, namely Bureau of...

In transportation planning there can be long lead times to adapt capacity. This paper addresses two questions. First, in a one mode world (say rail or road), what is the optimal capacity choice when faced with uncertain demand, long lead times and congestion. Using a simple analytical model it...

In this paper, we consider a region that invests in infrastructure used by both local demand and through transport. We then compare transport systems that have, for a given capacity, the same total infrastructure cost but vary in the proportion of fixed costs and variable capacity costs. We...
