A short time ago, decision support by operations research methods in railway companies was limited to planning (e.g., vehicle scheduling, duty crew rostering). In effect since December 12, 2004, the 2005 timetable of Berlin subway is based on results mathematical programming techniques. It first such service concept that has been put into daily operation. Profiting from these techniques, compared with previous timetable, today operates a offers shorter passenger waiting times—both at stops...
In the overwhelming majority of public transportation companies, designing a periodic timetable is even nowadays largely performed manually. Software tools only support planners in evaluating timetable, or by letting them comfortably shift sets trips some minutes, but they rarely use optimization methods. One main arguments against that there no clear objective practice, many criteria such as amount rolling stock required, average passenger changing time, speed trains, and number cross-wise...
Air and high-speed rail (AH) integration services are gaining ground with the development of railway airline industries. A well-designed feeder train timetable good synchronization is great significance in an AH service, because it can improve connectivity at transfer nodes offer more opportunities for intermodal passengers to travel. In this study, we propose a multi-objective model problem service synchronization. The aims optimization maximize number synchronizations coverage synchronized...
Periodic timetabling for railway networks is usually modeled by the Event Scheduling Problem (PESP). This model permits to express many requirements that practitioners impose on periodic timetables. We discuss a requirement are asking for, but which, so far, has not been topic of mathematical studies: concept symmetry. Several motivations why symmetric timetables might seem promising will be given. However, we provide examples showing symmetry leads suboptimality. To integrate into graph...
Within the metro networks of agglomerations all over world, circle lines play important roles with respect to network connectivity and passenger transfer. The train rescheduling problem a line under small disturbances is considered in this paper, including response rules for inserting standby trains, using storage tracks, holding. A mixed-integer nonlinear programming model proposed, aiming minimize timetable deviations, headway variations, number cancelled stops, rolling stocks, which then...
We consider the computation of periodic timetables, which is a key task in service design process public transportation companies. propose new approach for solving timetable optimisation problem. It consists (partially) heuristic network aggregation to reduce problem size and make it accessible standard mixed-integer programming (MIP) solvers. alternate invocation MIP solver with well-known specific modulo simplex (ModSim). This iterative helps ModSim-method overcome local minima...
