An innovative topology-based method for modeling railway train control systems is proposed in this paper. The method addresses the problems of having to rely too much on designers' experience and of incurring excessive cost of validation and verification in the development of railway train control systems. Four topics are discussed in the paper: 1) the(More)
Finding a correspondence between surfaces is a recurring problem in geometry processing applications. Many of the current approaches try to match the meshes directly in 3D. This is often complicated and makes it hard to produce good matches in a reasonable amount of time. This approach proposes a different way to tackle the problem by making use of already(More)
The authors of this paper review how complex entities, composed of many interdependent subsystems, such as international rail operators, can improve their ability to recover from incidents through the better management of key interfaces. The principles of Normal Accident Theory and resilience engineering are discussed, and the case study of the Eurostar(More)
Turnouts are probably the most important infrastructure elements of the railway system because of its effect on the system safety, reliability and quality of the service. In this paper, a predictive maintenance system in point mechanism, called RCM, has been implemented for increasing the quality service. RCM is based on the integration of the two other(More)
There usually exists a high density of traffic through bottleneck sections of mainline railways, where a perturbation of one single train could result in long consequential delays across a number of trains. In the event of disturbances, rescheduling trains approaching the bottleneck will be necessary to increase the throughput of the section. To model the(More)
Considering the growing demand for railway transportation, especially metros, and the changing social context, regular 24-hour operation is becoming a requirement. The railway is an inherently complicated and complex system and extending the service hours increases the level of difficulty in operating. In order to run all the services safely, punctually and(More)
