We study the Capacity Constrained Lot Size Problem with Setup Times (CLST). Based on two strong reformulations of the problem, we present a transformed refor...

In this article we introduce the Quadratic Capacitated Vehicle Routing Problem (QCVRP), a combinatorial optimization problem that arises in practical applica...
BibTeX reference
This paper proposes a state-of-the-art branch-cut-and-price algorithm for the vehicle routing problem with stochastic demands (VRPSD). We adapt the model of ...
BibTeX reference
This paper proposes a heuristic approach based on network flow techniques to schedule the production in open-pit mines, while accounting for metal uncertaint...
BibTeX reference
In the literature, the study of price subsidies of new technologies has focused on the tactical problem of achieving maximum penetration under a budget con...
BibTeX referenceCanadian Energy and Climate Policies: A SWOT Analysis in Search for Federal/Provincial Coherence
This paper presents an analysis of Canadian energy and climate policies in terms of the coherence between federal and provincial/territorial strategies. Afte...
BibTeX reference
In this paper we present a comparative study of several strategies that can be applied to achieve the so-called elementary lower bound in vehicle routing p...
BibTeX reference
Onshore oil fields may contain hundreds of wells that use sophisticated and complex equipments. These equipments need maintenance regularly to keep the...
BibTeX reference
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...
BibTeX referenceElectrification of the Canadian Road Transportation Sector: A 2050 Outlook with TIMES-Canada
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...
BibTeX reference
This paper proposes models and algorithms for the pickup and delivery vehicle routing problem with time windows and last-in-first-out (LIFO) loading constr...
BibTeX reference
In this paper we study a class of N -player finite-horizon linear-quadratic difference games with linear constraints. We introduce a specific information...
BibTeX reference
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 ...
BibTeX reference
Variable neighborhood search (VNS) is a meta-heuristic for solving optimization problems, whose basic idea is a systematic change of neighborhood structure...
BibTeX reference
Symmetric quasi-definite systems may be interpreted as regularized linear least-squares problem in appropriate metrics and arise from applications such as re...
BibTeX referenceFully Endogenous Growth with Increasing Returns and Exhaustible Resources: Existence and Stability
First-generation R&D-based endogenous growth models have been criticized because they predict strong scale effects (growth rate proportional to the size of...
BibTeX reference
We propose a new numerical method for evaluating long-maturity American put options. Most existing numerical approaches are based on the time discretization...
BibTeX reference
Why private labels (PLs) enjoy a large market in some countries while hardly penetrating others? What makes a market favourable to PL-product development? A...
BibTeX reference
The distance Laplacian of a connected graph G is defined by L = Diag(Tr) - D, where D is the distance matrix of G , and Diag(Tr) is the diagonal m...
BibTeX reference
We describe the most recent evolution of our constrained and unconstrained testing environment and its accompanying SIF decoder. Code-named SIFDecode and CU...
