The classical alternating current optimal power flow problem is highly nonconvex and generally hard to solve. Convex relaxations, in particular semidefinite,...

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...

The survivorship bias in credit risk modeling is the bias that results in parameter estimates when the survival of a company is ignored. We study the statist...

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...

The current trend of deeper and lower-grade deposits makes open pit mining less profitable. Mass mining alternatives have to be developed if mining at a si...

For over a decade, stochastic optimization has emerged as a framework that is capable of generating a life-of-mine production schedule that increases ne...

Twin Creeks is a gold mining complex part of Newmont's Nevada Operations. The mining complex is comprised of two open pits, Mega and Vista, external ore sour...

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...

Short-term production scheduling in open pit mining consists of defining the extraction sequence and process allocation of mineralized material over time-sca...

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...

The facility layout problem is concerned with finding an arrangement of non-overlapping indivisible departments within a facility so as to minimize the tota...

Relatively recent techniques for categorical simulations are based on multi-point statistical approaches where a training image is used to derive complex spa...

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%...
