In 1971, Graham and Pollack established a relationship between the number of negative eigenvalues of the distance matrix and the addressing problem in data c...

This article deals with the general theory of games played over uncontrolled event trees, i.e., games where the transition from one node to another is natu...

It is increasingly important to provide the relevant data for strategic decisions related to oil production and the marketing of oil products. We propose the...

In terms of energy resources, Canada is an important player on the world scene. However, the energy systems of the Canadian provinces and territories are muc...

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...

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 ...

This paper proposes a heuristic approach based on network flow techniques to schedule the production in open-pit mines, while accounting for metal uncertaint...

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...

This paper presents an analysis of Canadian energy and climate policies in terms of the coherence between federal and provincial/territorial strategies. Afte...

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...

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

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...

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...

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 ...

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

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...
