A Mixed-Integer-Linear-Programming Model for Rescheduling Freight Trains under an Unexpected Marshalling-Yard Closure

Summary - In this study, we consider rescheduling freight trains to reduce the effects of major interruptions. We assume that the interruption is an unexpected marshalling-yard closure, and we develop a macroscopic Mixed-Integer-Linear-Programming (MILP) model to reschedule the timetable. Furthermore, we design a rescheduling strategy of letting trains wait on the way when the destination yard has a closure. We consider stopping restrictions and the capacity of each segment and station in the model. The order of the trains affected by the interruption is not fixed. We present experimental results for three different cases of various sizes.
