Timetable management in universities is a complicated issue which uses up a great deal of human resources and is therefore very costly. This article deals with the analysis and design of an interactive decision support system for timetable management. This tool will be able to take hierarchical data organization into account and maintain coherence of the constraints on this data. Our research w...

Several European railway traffic networks experience high capacity consumption during large parts of the day resulting in delay-sensitive traffic system with insufficient robustness. One fundamental challenge is therefore to assess the robustness and find strategies to decrease the sensitivity to disruptions. Accurate robustness measures are needed to determine if a timetable is sufficiently ro...

Genetic algorithms (GA) have been applied to a number of optimisation problems with some success The algorithms mimic the process of natural selection, with the effect of creating a number of potentially optimal solutions to some complex search problem. One of the major disadvantages of genetic algorithms is that they are very slow. In this paper we discuss the application of a GA to the school...

The definition of train scheduling is going to shift its current static approach, as generally resulting in a timetable, towards dynamic approach where the timetable can be modified order enhance satisfaction passengers’ demand. In this paper, demand-oriented and rescheduling models are formalized propose that satisfy groups passengers. More specifically, assessment based on min max method. pro...

Railway planners have several tools to simulate the operation. Simulation allows the evaluation of the railway system’s quality by different points of view. Analyses of timetable stability and robustness include several indicators: recovery time and total delay among others. This paper formulates a model to describe the delay on a railway line. The total delay is characterized as a polynomial f...

We will consider the modeling and analysis of public transportation networks which evolve according to a timetable. Some results are summarized. A way to control these networks is introduced.

In most schools and colleges, producing a timetable is a task that is dreaded by those charged with annually creating it. In schools in particular , it can be difficult to produce any solution at all because teaching resources are usually stretched to the limit. This situation is made more difficult by the fact that the person making up the timetable must not only produce a valid solution but o...

Energy efficiency is an important concern in for railway administrations and operators. Strategies focused on traffic operation can achieve energy savings in short term and with associated low investments. For that purpose the main strategies are the design of efficient timetables and driving (ecodriving). The ecodriving applies coasting commands (null traction force) to reduce energy consumpti...
