Our research center has long time experience with optimization of human resources. We are focused primarily on applications from health care and transport sector but other domains interest us as well. Our specialty are problems with high number of shift types allowing to better cover personnel demand. The algorithms designed at our center are able to produce working plans for more than one hundred employees assuming planning horizons longer than one month and dozens of hard/soft constraints. We are also able to speedup these algorithms using learning techniques and parallel algorithms.
