- PublikationOptimizing staff rosters for emergency shifts for doctors(IEEE, 28.06.2009) Frey, Lukas; Hanne, Thomas; Dornberger, RolfThe creation of staff rosters for emergency shifts for doctors is a complex task. To construct good rosters, many restrictions (e.g. holydays and workload) have to be taken into account. These restrictions have been mathematically specified for a concrete case in order to solve the problem afterwards with a straightforward genetic algorithm. Thereby the main focus lays on two different mutation methods and the combination of them. The results of this procedure will be discussed in this work.04B - Beitrag Konferenzschrift
- PublikationMultiobjective and Preference-Based Decision Support for Rail Crew Rostering(IEEE, 18.06.2009) Hanne, Thomas; Dornberger, Rolf; Frey, LukasIn this paper we discuss a real-life problem in rail crew rostering. Specific emphasis is placed on the requirements of advanced approaches in rostering and the usage of optimization-based decision support. The modeling of the rostering problems is discussed including the treatment of constraints, the consideration of preferences, and the formulation of several objective functions. The specific solving method of the problem using an evolutionary algorithm and visualization and navigation tools for decision support are sketched briefly and some preliminary results are shown. Finally, some conclusions are presented.04B - Beitrag Konferenzschrift
