À propos de
l'événement
Le Centre interuniversitaire de recherche sur les réseaux d’entreprise, la logistique et le transport (CIRRELT) vous invite à un séminaire donné par M. Bernard Fortz, professeur au Département d’informatique à l’Université libre de Bruxelles.
Ce séminaire sera présenté en anglais.
Résumé
We consider an extension of the Unit Commitment (UC) problem with a second level of decisions ensuring that the produced quantities are cleared at market equilibrium. In their simplest form, market equilibrium constraints are equivalent to the first-order optimality conditions of a linear program. The UC in contrast is usually a mixed-integer nonlinear program (MINLP) that is linearized and solved with traditional Mixed Integer (linear) Programming (MIP) solvers. Taking a similar approach, we are faced to a bilevel optimization problem where the first level is a MIP and the second level linear.
Conférencier
Bernard Fortz is Professor in the Computer Science Department of the Université libre de Bruxelles (ULB) since 2006. He is currently head « Graphs and Mathematical Optimization » team. He holds a master degree in mathematics from the University of Namur (1993) and a Ph.D. degree in Operations Research, obtained in ULB in 1998. He then worked as postdoctoral researcher at AT&T Research-Labs and Maastricht University. From 2000 to 2006, he was associate professor at the Louvain School of Management (Université catholique de Louvain).
His main research interests are combinatorial optimization, network design applications, optimization of routing protocols in the telecommunications networks, bilevel optimization and applications in energy. He is associate editor of INFORMS Journal on Computing and International Transactions on Operational Research and coordinator of the EURO Working Group on Network Optimization (ENOG). From 2012 to 2017, he has also been coordinator of the inter-university attraction centre « Combinatorial Optimization: Meta-heuristics and Exact Methods » funded by the Belgian federal government. Since May 2015, he is vice-head of the cross-border team INOCS, partnership between INRIA Lille and ULB.
