La production hydroélectrique joue un rôle crucial dans le paysage énergétique mondial en offrant une source d'électricité renouvelable et durable. La prévis...

This work presents a new strategy to virtual bidding based on distributionally robust optimization (DRO) using a Wasserstein distance. Virtual bidding, a mec...

The \(p\)-median problem is a classical location problem where the goal is to select \(p\) facilities while minimizing the sum of distances from each loc...

Local search methods start from a feasible solution and improve it by successive minor modifications until a solution that cannot be further improved is enco...

This paper introduces a new approach to nurse scheduling that integrates employee well-being into the decision-making process. A random forest regressor is t...

Le 4 févriere 2025 a eu lieu la 5e édition de la journée des étudiant(e)s du GERAD, sous le thème de la transition énergétique. Le but de cet événement était...

Bilevel optimization has garnered growing interest over the past decade. However, little attention has been paid to detecting and dealing with unboundedness...

We consider chemical graphs that are defined as connected graphs of maximum degree at most 3. We characterize the extremal ones, that is, those that maximize...

Integrating Optical Transport Networks (OTNs) into multilayer Elastic Optical Networks (EONs) enhances data transmission efficiency but introduces significan...

High-impact climate damages are often driven by compounding climate conditions. For example, elevated heat stress conditions can arise from a combination of ...

Planners in different industries use optimization software for decision-making. In numerous practical applications, these optimization tools are often not re...

Le Quatorzième atelier de résolution de problèmes industriels de Montréal, qui eut lieu du 13 au 17 mai 2024, fut organisé conjointement par le Centre de rec...

À mesure que le changement climatique s'intensifie, la transition vers des sources d'énergie plus propres devient de plus en plus urgente. Avec l'accélératio...

Les réseaux optiques élastiques (EON) sont confrontés à la fragmentation du spectre, qui peut entraver l'établissement de nouvelles connexions. Bien que le c...

This paper tackles a complex variant of the unit commitment (UC) problem at Hydro-Quebec, referred to as the transient stability constrained unit commitmen...

We propose an approach to construct text-based time-series indices in an optimal way -typically, indices that maximize the contemporaneous relation or the pr...

Millions of oil and gas wells are abandoned and orphaned around the world. Due to funding shortfalls, many abandoned and orphaned wells remain unplugged and ...

The arithmetic-geometric index is a newly proposed degree-based graph invariant in mathematical chemistry. We give a sharp upper bound on the value of this ...

Le Treizième atelier de résolution de problèmes industriels de Montréal, qui eut lieu du 21 au 25 août 2023, fut organisé conjointement par le Centre de re...

We reassess Boehmer et al. (2021, BJZZ)'s seminal work on the predictive power of retail order imbalance (ROI) for future stock returns. First, we replicate ...
