Cutoff grade specifies the available supply of metallic ore from an open pit mine for the multiple processing and refining streams of the corresponding minin...

Mining operations can be modelled as a supply chain from the sources of raw material (mines) through various processing streams to the final saleable product...

Preferential sampling of high grade zones is a common practice in the drilling campaigns of ore deposits. This may lead to a bias in the statistics derived f...

Unconditional consensus is the property of a consensus algorithm for multiple agents, to produce consensus irrespective of the particular time or state at wh...

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

Parkinson's disease (PD) is a multifactorial disease known to result from a variety of factors. Although age is the principal risk factor, other etiological ...

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...

In this paper we propose the use of twin graphs for optical transport network (OTN) physical topology design. Some properties inherent to twin graphs are fa...

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...
