We propose railway line planning optimization models that determines the frequency of each train so that it can meet passenger origindestination demands while minimizing the related costs. Most line planning models assume that all trains on a supply network stop at all intermediate stations. However to minimize passenger travelling time and provide train service to as many stations as possible,...

In transportation sector implemented deregulation processes as well as increased free competition in the global scale have been key change drivers in recent decades. This research work analyzes in retrospective shareholder value creation in North American railway freight and peer group of four transportation companies from Europe and one from Asia. Research shows that North American, and partic...

Railway timetable planning is one of the key factors in successful operation a railway network. The must satisfy all operational restrictions at microscopic representation network, while maximizing transportation capacity for passengers and freight. an NP-Hard problem, difficult to solve large-scale networks, such as those entire countries. In this work, we propose logic Benders decomposition a...

China’s Railway Transportation (CRT) is enjoying a time of unprecedented development thanks to huge government investment and a series of aggressive favorable policies. Understanding the opportunities and challenges facing the CRT affords the practitioners and policy makers a better perception of development regarding this important transportation mode. This paper attempts to comprehensively as...

Almost all trains have to run according a schedule. One exception may be some freight trains which may start at a random time. Unfortunatly, for some reasons, some minor problems occur and lead to have delays. Due to limited ressources available (tracks, cars,. . . ), a small problem can lead to a chain of delays. To monitor the traffic and take decisions are the main goals of the train dispatc...

The expansion of economic activities and increasing mobility of people on short, medium and long distance trips is an issue that requires attention in the transport industry. The need to address this demanding issue in a sustainable and economically efficient way is the core of general capacity challenge in railway industries. This informs the strategic objective of ensuring an efficient and co...
