Prioritization of Trains: mathematical model

Abstract

We present a mathematical optimization model suitable for providing decision support on train dispatching on small and medium sized regional lines. An implementation of the model has undergone extensive real life testing at the Stavanger train dispatching central on the Stavanger- Mol line from February to October 2014. During this test period the model has been solved about 40 000 times, typically finding the optimal solution within two-four seconds.
