In the CAPMO-Train project, we aimed to illuminated the possibilities of automated, optimized train-dispatcher shifts that take all legal and operational restrictions into account and integrate train-dispatcher workload. To this end, we developed an optimization frame-work for shift scheduling. We exemplified our framework with results for Malmo¨ dispatching center, but the framework itself is flexible and can be applied for other dispatching centers. We derived the number of train movements in a dispatching area during a time period as an approximation for the objective task load (which is correlated to the subjective dispatcher workload) and inferred an upper bound for this approximation based on discussion with operational experts. Together with legal and operational requirements for train-dispatcher shifts, this task-load measure build the basis for the optimization framework.
