In this paper we study the linear quadratic regulation (LQR) problem for dynamical systems coupled over large-scale networks and obtain locally computable l...
référence BibTeXValue-based production planning in non-ferrous metal industries: Application in the copper industry
Production planners in the non-ferrous metal industry face an inherent combinatorial complexity of the metal production process within a fast changing market...
référence BibTeX
The complex-step derivative approximation is a numerical differentiation technique that can achieve analytical accuracy, to machine precision, with a single ...
référence BibTeXSolving a real-world multi-period petrol replenishment problem with complex loading constraints
In this paper, we solve a rich real-word Multi-Depot Multi-Period Petrol Replenishment Problem with a heuristic based on Branch-and-Price heuristic. The netw...
référence BibTeXLearning chordal extensions
A highly influential ingredient of many techniques designed to exploit sparsity in numerical optimization is the so-called chordal extension of a graph repre...

This work proposes strategies to handle three types of constraints in the context of blackbox optimization: binary constraints that simply indicate if they a...
référence BibTeX
This paper studies the team orienteering problem, where the arrival time and service time affect the collection of profits. Such interactions result in a non...
référence BibTeX
We propose a generalized decomposition approach for production planning problems with process configuration decisions. These problems appear in contexts wher...

This work introduces StoMADS, a stochastic variant of the mesh adaptive direct-search (MADS) algorithm originally developed for deterministic blackbox optim...
référence BibTeXAn exact dynamic programming algorithm for the precedence-constrained class sequencing problem
This article discusses the precedence-constrained class sequencing problem (PCCSP). In scheduling terms, this is a one-machine scheduling problem with preced...
référence BibTeX
Dealing with demand uncertainty in multi-item lot sizing problems poses huge challenges due to the inherent complexity. The resulting stochastic formulation...

We introduce an iterative method named BiLQ for solving general square linear systems \(Ax=b\)
based on the Lanczos biorthogonalization process defined by ...
Nous déterminons le prix optimal et la quantité commandée de deux produits substituts offerts dans deux marchés, dont l'un est saisonnier avec un potentiel d...
référence BibTeXSustainable city logistics via access restrictions? An impact assessment of city center policies
Cities are facing severe traffic-related problems causing emission thresholds to be exceeded. All around the world, city center access restriction policies a...
