The Operations Department of HEC Liège – Management School of the University of Liège is looking for a PhD researcher in Management Sciences, with a specialization in Operations Research (optimization, algorithmics, decision support).

The topic of the PhD is the development of proactive and reactive optimization methods for dynamic and stochastic home healthcare routing and scheduling problems: Home healthcare routing and scheduling problems (HHCRSPs) are complex combinatorial optimization problems where the medical tasks of geographically dispersed patients must be assigned to available care workers and scheduled considering treatment requirements and patient preferences. The rosters of the care workers must also be determined for the planning horizon while respecting workforce-related constraints. Moreover, those operational processes are subject to unexpected disruptions that can have dramatic effects on the quality of healthcare services. This research project aims at designing novel proactive and reactive optimization methods for the HHCRSPs arising in uncertain and dynamic environments. The goal here is to account for the inherent uncertainty and to generate routes, schedules, and rosters that are robust and responsive when facing disruptions.
