Cet article présente une caractérisation des graphes pour laquelle le rayon spectral du Laplacien sans signe q₁ est extrémal lorsqu'un invarian...

Onshore oil fields may contain hundreds of wells that use sophisticated and complex equipments. These equipments need maintenance regularly to keep the...

In this paper we consider the vehicle routing problem with hard time windows and stochastic service times (VRPTW-ST); in this variant of the classic VRPTW ...

This paper deals with the development of an efficient iterative method to solve the chance-constrained generation expansion planning (GEP) problem. Reliabili...

In this paper we evaluate the performance and compare 19 different heuristics for solving continuous global optimization. They are all based on the following...

We compare the use of price-based policies or taxes, and quantity-based policies or quotas, for controlling emissions in a dynamic setup when the regulator...

In this paper, we suggest DE-VNS as a new heuristic that combines two well known metaheuristic approaches: Differential Evolution (DE) and Variable Neighbour...

Avoiding or preventing deadlocks in simulation tools for train scheduling remains a critical issue, especially when combined with the objective of minimizing...

Optical networks, given their excellent characteristics in terms of high bandwidth and low latency, play a crucial role in enabling today's applications that...

We use a newly developed bottom-up model of the entire Canadian energy system (TIMES-Canada) to assess potentials for electrification of the road transport s...

Le nombre de Cahiers du GERAD vient de dépasser 2000. C'est un nombre qui en dit long sur l'activité du centre. Nous profiterons de cette occasion pour fa...

This paper proposes models and algorithms for the pickup and delivery vehicle routing problem with time windows and last-in-first-out (LIFO) loading constr...

In this paper we study a class of N -player finite-horizon linear-quadratic difference games with linear constraints. We introduce a specific information...

In this paper, we study N -player finite-horizon discrete-time dynamic stochastic games where the uncertainty is described by an event tree. We consider ...

In this paper we present a novel experimental platform for network management able to dynamically optimize the energy consumption of backbone IP networks ope...

Variable neighborhood search (VNS) is a meta-heuristic for solving optimization problems, whose basic idea is a systematic change of neighborhood structure...

Attractive travelling salesman problem (AtTSP) consists of finding maximal profit tour starting and ending at a given depot after visiting some of the faci...

Symmetric quasi-definite systems may be interpreted as regularized linear least-squares problem in appropriate metrics and arise from applications such as re...

First-generation R&D-based endogenous growth models have been criticized because they predict strong scale effects (growth rate proportional to the size of...

We propose a new numerical method for evaluating long-maturity American put options. Most existing numerical approaches are based on the time discretization...
