Price and Frequency Competition in Freight Transportation
This paper develops a simple analytical model of price and frequency competition among freight carriers. In the model, the full price faced by a shipper (a goods producer) includes the actual shipping price plus an inventory holding cost, which is inversely proportional to the frequency of shipments offered by the freight carrier. Taking brand loyalty on the part of shippers into account, compe...
متن کاملThe Energy-Efficient Operation Problem of a Freight Train Considering Long-Distance Steep Downhill Sections
With the energy consumption rising in rail transport, the railway sector is showing increasing interest in the energy-efficient operation of freight trains. Freight trains require more complicated driving strategies than ordinary passenger trains do due to their heavy loads, especially in the long-distance steep downhill (LDSD) sections that are very common in freight rail lines in China. This ...
متن کاملFleet Size and Frequency in Rapid Transit Systems
Given is a set of stations linked by railway tracks, forming an undirected railway network. One or more lines are formed in this network. Each line consists of an origin station, a destination station, and a number of intermediate stations. In order to complete the line configuration, you need to decide the frequency (number of services per hour) and the capacity (number of carriages) for each ...
متن کاملDynamic Models for Freight Transportation
Freight transportation is characterized by a variety of dynamic information processes: the demands of customers, the performance of people and equipment, and the performance of the network. In addition, large networks are characterized by how they organize decisions and information: who makes what decision with what information? This chapter approaches the development of models for freight tran...
متن کاملConcurrent Locomotive Assignment and Freight Train Scheduling
The locomotive assignment and the freight train scheduling are important problems in railway transportation. Freight cars are coupled to form a freight rake. The freight rake becomes a train when a locomotive is coupled to it. The locomotive assignment problem assigns locomotives to a set of freight rakes in a way that, with minimum locomotive deadheading time, rake coupling delay and locomotiv...
