HEC Liège invites applications for a full-time assistant position in Operations Research

The Operations Department of HEC Liège – Management School of the University of Liège is looking for an assistant in Management Sciences, with a specialization in Operations Research (optimization, algorithmics, decision support). The assistant position consists of a PhD research and supervising exercise sessions.

The PhD is co-supervised by Professors Jérôme De Boeck and Bernard Fortz. The proposed topic considers the use of mathematical optimization techniques together with machine learning for the electricity supply chain with a particular focus on the Unit Commitment problem (UC). The UC consists of determining the planning of power generators in order to meet a given demand and minimizing cost. Power generators have a large variety of technical constraints. Determining when to use a given power generator and what quantity of electricity to produce is not as trivial as turning an on/off switch due to these technical constraints. This problem has been widely studied in the literature with mathematical optimization techniques but little work has been done for the UC with machine learning. In the context of energy transition and the increasing use of renewable energies, the UC becomes a more challenging problem leading to several modelization and computational challenges when using mathematical optimization techniques. The technical constraints of power generators do not vary over time, only the demand in electricity and the weather conditions change on a daily basis and will influence the planning of energy production. The research will build over this observation. The aim is to use machine learning methods to learn how the planning of generators is influenced by the parameters changing on a daily basis in order to improve state-of-the-art mathematical optimization methods used for the UC. The applicant is free to propose another topic of research in accordance to the objectives of HEC Liège and can be discussed with the supervisors before submitting an application.

The supervision of exercise session will be in the field of operations research and given in English with a maximum workload of 300 h/year.
