Повний текст джерелаOn-line re-scheduling of trains aims to find accurate solutions after an incident has occurred on the railway network. When we consider a large area, solutions consist in calculating new timetables, sequences and routes of trains. This problem asks for decision support tools based on operational research techniques.This thesis aims to develop solutions toward an operational tool, it articulates around three main parts. The first part defines an exhaustive model of the railway system operations and a multiscalable description of the infrastructure.The second part presents three mathematical models of the rescheduling problem associated with this description. We preset a exhaustive continuous time based model including headways that take into account speeds of trains, plus a discrete time based model and an hybrid model combining both formulations.The last part describes first implementations and the global framework we need to develop in order to solve the real world problem. It emphases on expected synergies, specilaly between simulation and optimization techniques

Повний текст джерелаOver the last twenty years, public transport issues in the Paris region have become a major concern. The French national railway company, which operates most of the rail network in this region, plays a central role in the organisation of transport. However, in contrast to expectations in this sector, rail traffic is experiencing a number of malfunctions. As part of an overall approach to questioning the principles of rail operation in dense areas, this thesis provides a new look at the origin of delays affecting trains. Drawing on road traffic tools and in particular the basic network diagram, the basic railway line diagram is defined for railways, which makes it possible to represent the flow as a function of concentration on a portion of a railway line. This tool is then used to compare the results from our model with a set of data measured on two railway lines in the Paris region, which shows that our model can qualitatively reproduce the traffic congestion phenomena observed on real cases.(Translated with www.DeepL.com/Translator)

Повний текст джерелаThe design of a railway transportation plan is a process achieved between two years and six months before it is put into service. The main phases in the design of a transportation plan are the line planning, the timetabling, the rolling stock and the crew scheduling.The design of the transportation plan can have many consequences on the quality of service: an inadequate frequency in station can cause a loss of passengers, sufficient number of seated places, robustness of the timetable in the face of small incidents... In dense area, as in the Ile-de-France region, all these elements must be taken into account as the transportation plan is designed.Today, SNCF Transilien designs its transportation plans by first taking into account the optimization of production resources (train paths, rolling stock units and drivers). However, today, the increase in resources implemented no longer improves the adequacy of the transportation plan to passengers’ demand. This design method no longer makes it possible to cope with the increase in the demand for mobility (+3% each year since 2000). This is why we must rethink the design of the transport plan by immediately integrating the passenger dimension. Our work focuses on issues of line planning and timetabling in a passenger-oriented approach. First, we present a multi-objective model for line planning. Then, we present a model of timetabling incorporating passenger route choice. Then, we initiate a method to integrate these two models. Finally, we present an evaluation of our results thanks to reliability indicators from the literature and a macroscopic simulation of the timetables

Повний текст джерелаThe current thesis takes place in the framework of fine 1 automation project. It is a project that consists of upgrading fine 1 (with drivers on-board) to unattended train operation (no drivers or agents on-board) without service interruption. It results a mixed fleet operation for a period of two years between manually driven trains and driverless ones. In this context, my research work consists of continuing in a first step the development of software destined to study and analyse the mixed fleet operation on fine 1. Once operational; the model has served as a simulation in two case studies that I elaborate in a second step. These two case studies aim to answer problematical matters affecting the management of the mixed trains running inside the terminal stations. They take into account two opposite constraints: people-staff safety on one hand and quality of service offered to passengers on the other hand. The analysis and the results of these two case studies will be described in the current PhD report

Повний текст джерелаThe reliability control of critical electronic components is one of the challenges to be faced by railway stakeholders. IGBT (Insulated Gate Bipolar Transistors) power modules belong to this list of components. They are subject to high stresses corresponding to those encountered in harsh railway environments. The environmental conditions encountered in rail operations and the demanding availability requirements impose high levels of reliability on IGBT. In order to improve their reliability, an evaluation methodology has been developed based on a probabilistic approach and supported by a Bayesian network. For the implementation of the model, several working elements were assembled. First, an original approach called "U-Cycle" was proposed, highlighting in a one-to-one way a system level associated with the train and a component level similar to the IGBT considered simultaneously according to functional and dysfunctional views. In this context, the work led, first, to highlight the mechanisms characterizing, in a top-down logic, the influence of train loading on component stress and, in a bottom-up logic, the dysfunctional impact of the failure at component level on system reliability. In a second step, the results of this analysis led to the implementation of the structure of a Bayesian model whose generic nature allows it to be deployed for the reliable modelling of any type of rail system. The modelling work based on Bayesian networks is used to support the reconciliation between analytical models (failure physics) and data from the use of the elementary component in its operating environment. The model was used to model the reliability of an IGBT in an application framework corresponding to the metro in the city of Chennai, India. The data and expert knowledge collected on the project made it possible to determine the probability tables of the Bayesian network. The probabilistic results of the model have been translated into reliability indicators

Повний текст джерелаPublic transport management is currently going through important changes, passing from one scale to another: decentralizing from the national level and extending at the local level. The range of transport management powers of the French administrative regions have widened, thus creating new management problems. Within the context of these new questions, our research proposes management solutions which take into account both the continual evolution of daily mobility and the new scales of transport management. More specifically, we considered a specific stage often neglected in geographical approaches to the suject. This stage called traffic generation consists in modelling the process of choice at the point origin of an individual journey. So far, the way that these questions have been treated using transport economy methods has obscured an important stage in the conception of traffic generation, the geographical stage. This stage relates to the zoning of the study area which constrains trip generation. We propose here to carry out the complete modelling of the traffic generation stage in the Franche-Comté region. This includes the understanding and the delimitation of our study area. Other results are the creation of a relevant zoning system in relation to management issues, in order to produce a final assessment of trip generation for the zoning system

Повний текст джерелаThe aim of the doctoral thesis is to contribute on the developpement of real-time traffic control algorithms for mass transit railway systems with junctions, located in urban areas. The scientific ambition of the doctoral thesis is to develop a traffic model with a finer modelisation of the train-passengers interaction. The model will allow a more precise evaluation of the level of service offered to the passengers and of the decisions taken by the operator of the line. Basing on this modeling, we will develop a control algorithm (strategic/ tactical and operational) in order to enhance the service quality on the line. The objective of the Paris metro system operator, financing this thesis, is to have a ready-to-implement control system for a railway line with a junction

Повний текст джерелаThis project aims at an optimization of geostructural modeling methodolgies, leading to a better knowledge and a better management of the rock risk impacting the railway system. Acquired 3D models are exploited in order ton convert 3D point clouds into geostructural analysis. Hence, we have developed a semi-automatic process that allows 3D models to be combined with the results of field surveys in order to provide more precise analyses of rock faces, for example, by classifying rock discontinuities into subsets according to their orientation. A second approach is proposed, combining both 3D point clouds (from LiDAR or image matching) and 2D digital images. Combining these high-quality data with the proposed automatic and manual processing method greatly improves the geometrical analysis of rock faces, increases the reliability of structural interpretations, and enables reinforcement procedures to be optimized
