This paper presents a gain-scheduling wind-turbine control strategy to mitigate the effects of adverse weather conditions on degradation drive-train. By choosing suitable gain according wind class, it is possible establish trade-off between generated energy and drive-train degradation. The dissipated in mechanical transmission used as an indicator modeled flexible shaft using nonlinear dynamics...

Urban rail crew scheduling problem is to allocate train services to crews based on a given train timetable while satisfying all the operational and contractual requirements. In this paper, we present a new mathematical programming model with the aim of minimizing both the related costs of crew duty and the variance of duty time spreads. In addition to iincorporating the commonly encountered cre...

The timetable of a metro system is essential for trains running safely and efficiently. For the design timetable, potential power interruptions energy supplies from substations to should be borne in mind. In case occur, backup plan completed responsively accommodate passenger demands this study, we propose an supplementation strategy utilizing regenerative decelerating event develop tri-objecti...

Starting from the defined network topology and the timetable assigned beforehand, the paper considers a train rescheduling in respond to disturbances that have occurred. Assuming that the train trips are jobs, which require the elements of infrastructure – resources, it was done by the mapping of the initial problem into a special case of job shop scheduling problem. In order to solve the given...

In this paper the results of a locomotive scheduling problem faced by National Railways of Zimbabwe (NRZ) are presented. The study is in part inspired by similar optimization problems in public transports. This paper focuses on the planning version of the locomotive scheduling model (LSM), where there are multiple types of locomotives and a decision is made as to which set of locomotives is to ...

Abstract. This paper addresses the problem of generating conflict-free periodic train timetables for large railway networks. We follow a two level approach, where a simplified track topology is used to obtain a macro-level schedule, and the detailed topology is considered locally on the micro level. To increase the solution space in the interface of the two levels, we propose an extension of th...
