Application of an iterative framework for real-time railway rescheduling

Twan Dollevoet, Dennis Huisman, Leo G. Kroon, Lucas P. Veelenturf, Joris C. Wagenaar
2017 Computers & Operations Research  
In this research, we describe an iterative framework in which all three resources are considered. The framework applies existing models and algorithms for rescheduling the individual resources.  ...  We extensively test our framework on instances from Netherlands Railways and show that schedules which are feasible for all three resources can be obtained within short computation times.  ...  Here, the macroscopic timetabling problem is modelled using an event activity network.  ...
