Book Description
This monograph presents a framework for optimum design of timetables to maximise schedule robustness and minimise resource deployment, especially for large railway networks, wherein the problem has been formulated as a multi-objective non-linear model. The monograph s contribution is the formulation of methods to reduce the problem size to computationally manageable proportions, and thus enable planners to undertake network-wide optimisation studies. The monograph demonstrates that the design of timetables can be spread over a canvas incorporating not only over the entire railway network, thus enabling study of the mutual interactions across the network, but also involving the optimisation of crew and rolling stock in the purview of the model. This can thus emulate the planning process more truthfully, wherein piecemeal optimisations are of little import. This monograph should be especially useful for researchers engaged in problems pertaining to railway networks, railway network planners, railway decision support software developers or one interested in industrial applications of operations research.

Book Description
We have developed a non-linear multi-objective model for optimal design of railway timetables. The objectives of the model are to maximize schedule reliability and minimize energy consumption, rolling stock and crew deployment. Metrics have been derived for each of these objectives. AHP is used to determine the relative weights of the objectives, while GCA & TOPSIS techniques are used for optimization, which is demonstrated on a test case.

Book Description
The book comprises a number of research papers presented at several Computers in Railways Conferences. It has been compiled by Ingo A. Hansen, President of the International Association of Railway Operations Research (IAROR) and comprises selected papers originating from different countries, such as Denmark, France, Germany, Japan, Italy, Netherlands, Sweden and Switzerland. The papers give an overview of the current state-of-the-art analytical approaches, methods and simulation tools for the modelling and analysis of network timetables, the distribution of train delays and real-time rescheduling of perturbed operations. The topics include e.g. railway capacity estimation according to the UIC norm 406, train punctuality analysis based on standard track occupation and clearance data, and boarding, alighting and distribution of passengers along suburban trains, as well as fast recognition and resolution of conflicts between train movements in case of disturbances by means of real-time speed adaptation, re-ordering or re-routing. The book can serve as an introduction to the theory of railway traffic, timetable design, operations analysis, simulation, safety and control for Master and PhD students from engineering faculties and professionals working in the railway industry.

Book Description
Scheduled transportation networks give rise to very complex and large-scale networkoptimization problems requiring innovative solution techniques and ideas from mathematical optimization and theoretical computer science. Examples of scheduled transportation include bus, ferry, airline, and railway networks, with the latter being a prime application domain that provides a fair amount of the most complex and largest instances of such optimization problems. Scheduled transport optimization deals with planning and scheduling problems over several time horizons, and substantial progress has been made for strategic planning and scheduling problems in all transportation domains. This state-of-the-art survey presents the outcome of an open call for contributions asking for either research papers or state-of-the-art survey articles. We received 24 submissions that underwent two rounds of the standard peer-review process, out of which 18 were finally accepted for publication. The volume is organized in four parts: Robustness and Recoverability, Robust Timetabling and Route Planning, Robust Planning Under Scarce Resources, and Online Planning: Delay and Disruption Management.

Book Description
This volume features the proceedings of the Eleventh International Conference on Computer System Design and Operation in the Railway and other Transit Systems. It provides the latest information on the use of computer-based techniques, and promotes a general awareness of these throughout the business management, design, manufacture and operation of railways and other advanced passenger, freight and transit systems. Of interest to railway managers, consultants, railway engineers (including signal and control engineers), designers of advanced train systems and computer specialists, the proceedings will also be of interest to planners of railway network systems, manufacturers of the track, rolling stock, locomotives and other ancillary equipment and systems; who all have a common interest in the development and application of computer techniques for the solution of problems in the railway and other mass transit systems. Papers included in this volume cover the following topics: Planning; Safety and security; Passenger interface systems; Decision support systems, Computer techniques; Driverless operations; Advanced train control; Train location; Dynamic train regulations; Timetable planning; Operations quality; Communications, Energy management; Power supply; Dynamics and wheel/rail interface; Freight; Condition monitoring; Asset management; Maglev and high speed railway.

Book Description
Rail is potentially a very efficient form of transport, but must be convenient, reliable and cost-effective to compete with road and air transport. Optimal control can be used to find energy-efficient driving strategies for trains. This book describes the train control problem and shows how a solution was found at the University of South Australia. This research was used to develop the Metromiser system, which provides energy-efficient driving advice on suburban trains. Since then, this work has been modified to find practical driving strategies for long-haul trains. The authors describe the history of the problem, reviewing the basic mathematical analysis and relevant techniques of constrained optimisation. They outline the modelling and solution of the problem and finally explain how the fuel consumption can be minimised for a journey, showing the effect of speed limits and track gradients on the optimal driving strategy.

Book Description
This book promotes the use of mathematical optimization and operations research methods in rail transportation. The editors assembled thirteen contributions from leading scholars to present a unified voice, standardize terminology, and assess the state-of-the-art. There are three main clusters of articles, corresponding to the classical stages of the planning process: strategic, tactical, and operational. These three clusters are further subdivided into five parts which correspond to the main phases of the railway network planning process: network assessment, capacity planning, timetabling, resource planning, and operational planning. Individual chapters cover: Simulation Capacity Assessment Network Design Train Routing Robust Timetabling Event Scheduling Track Allocation Blocking Shunting Rolling Stock Crew Scheduling Dispatching Delay Propagation
