The Effects of Shift Generation on Staff Rostering

To the best of our knowledge, this is the first paper to examine the effect of shift structures on staff rostering optimization. The study showed that the generated shift structures have a significant effect on optimizing the staff rosters. The study also showed that we should allow longer working days, because they imply better consideration of the stress and risk factors introduced by the Finnish Institute of Occupational Health. The PEASTP metaheuristic, a computational intelligence framework, was used to justify the findings. The results were obtained using a real-world instance from a Finnish contact center.
