The Canadian province of Quebec has set for 2030 a greenhouse gas (GHG) emission reduction target of 37.5% below 1990 levels. Meeting such a reduction targ...

Dans cet article, nous proposons une méthode d'optimisation sans factorisation pour les problèmes avec contraintes d'égalité pour lequel toutes les contrai...

For optimization problems involving many nonlinear inequality constraints, we extend the bound-constrained (BCL) and linearly-constrained (LCL) augmented-La...

In this paper we consider a version of the capacitated vehicle routing problem (CVRP) where travel times are assumed to be uncertain and statistically corre...

Within state-of-the-art optimization solvers such as IBM--CPLEX the ability to solve both convex and nonconvex Mixed-Integer Quadratic Programming (MIQP) pro...

L’imitation d’une marque connue est une pratique courante et peut être légale ou illégale (dans le cas de la contrefaçon). On considère un scénario où une f...

In the last 20 years, there has been increasing interest in using advanced simulation and optimization techniques to develop and manage mineral resources a...

A mining complex is a mineral value chain that consists of multiple activities, starting from material extraction to a set of sellable products delivered t...

Signatories of the Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC) are exploring avenues to drastically abate their ...

The multiple depot vehicle scheduling problem (MDVSP) has been widely studied in the context of public transit systems. It consists of building vehicle sched...

In global liner shipping networks a large share of transported cargo is transshipped at least once between container vessels, and the total transportation ti...

Canada was a proactive participant in developing the Paris Accord (COP 21; December, 2015), and committed to reduce its greenhouse gas (GHG) emissions by 30%...

Soient \({\mathcal D(G)}\), \({\mathcal D}^L(G)={\mathcal Diag(Tr)} - {\mathcal D(G)}\) et \({\mathcal D}^Q(G)={\mathcal Diag(Tr)} + {\mathcal D(G)}\),...

Soit \(G\) un graph d'ordre \(n\). L'énergie \(\mathcal{E}(G)\) d'un graph simple \(G\) est la somme de des valeurs absolues des valeurs propres de s...

Despite the lack of theoretical and practical convergence support, the Nelder-Mead (NM) algorithm is widely used to solve unconstrained optimization proble...

The mining value chain comprises many inter-related components, from mines to transportation, to customers. When the individual components are optimized sep...

We analyze the effect of non-constant discounting on economic growth and social welfare in an endogenous growth model with pollution externalities. For ti...

Climate change is one of the greatest environmental challenges facing our planet in the foreseeable future, yet, despite international environmental agreemen...

This note revisits the problem of how to select an equilibrium in a differential game in the case of multiplicity of Nash equilibria. Most of the previous ap...

In this paper, we focus on the problem that has been described in the second international nurse rostering competition: a personalized nurse scheduling prob...
