Shunting scheduling problems at railway depot can be regarded as a sort of resource constrained project scheduling problem (RCPSP). Unlike the normal RCPSPs, however, shunting scheduling problems require that the number of activities which form a project has to be dynamically changed in the problem solving process and some of the activities have to be performed at a prescribed timing, for examp...

In light of the improvements to capacity and timeliness heavy-haul railway transportation that can be organized through group trains originating at a technical station, we address train operation scheduling problem with freight demand importance via newly proposed mixed integer programming model simulated annealing algorithm. The optimization objective is minimize weighted sum cost total cargo ...

With the development of wireless communication, people have put forward higher requirements for train-ground communications in high-speed railway (HSR) scenarios. help mobile relays (MRs) installed on roof train, application Millimeter-Wave (mm-wave) communication which has rich spectrum resources to system can realize high data rate, so as meet users’ increasing demand broad-band multimedia ac...

The purpose of this research is to using ant colony optimization (ACO) to develop a heuristic algorithm to solve the train timetabling problem. This algorithm takes into consideration the trains scheduling in the transit period between peak period and off-peak period, the conflict resolving and the balance of in and out trains for each depot. A case study using the Taipei MRT is giving to demon...

Transshipment yards, where gantry cranes allow for an e cient transshipment of containers between di erent freight trains, are important entities in modern railway systems and facilitate the general shift from point-to-point transport to hub-and-spoke railway systems. Modern rail-rail transshipment yards accelerate container handling, so that multiple smaller trains with equal destination can b...

At a planning level, train scheduling consists of optimizing the routing and scheduling for a set of trains on a railway network. In real-time operations, however, the planned schedule constantly needs to be verified and possibly updated due to disruptions/delays that may require train rerouting or cancelation. In practice, an almost immediate reaction is required when unexpected events occur, ...

Railway crew scheduling problem is the process of allocating train services to the crew duties based on the published train timetable while satisfying operational and contractual requirements. The problem is restricted by many constraints and it belongs to the class of NPhard. In this paper, we develop a mathematical model for railway crew scheduling with the aim of minimising the number of cre...
