In the last 20 years, there has been increasing interest in using advanced simulation and optimization techniques to develop and manage mineral resources a...
BibTeX referenceStochastic optimization of long-term block cave scheduling with hang-up and grade uncertainty
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...
BibTeX referenceStochastic orebody modelling and stochastic long-term production scheduling for an iron ore deposit
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...
BibTeX referenceSimultaneous stochastic optimization of production scheduling at Twin Creeks mining complex, Nevada
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...
BibTeX reference
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...
BibTeX reference
Short-term production scheduling in open pit mining consists of defining the extraction sequence and process allocation of mineralized material over time-sca...
BibTeX reference
Signatories of the Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC) are exploring avenues to drastically abate their ...
BibTeX reference
Relatively recent techniques for categorical simulations are based on multi-point statistical approaches where a training image is used to derive complex spa...
BibTeX reference
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%...
BibTeX reference
As more and more data about mining complex operations is collected and stored, it becomes increasingly important for computer systems to help human operators...
BibTeX reference
The mining value chain comprises many inter-related components, from mines to transportation, to customers. When the individual components are optimized sep...
BibTeX referenceNon-constant discounting, social welfare and endogenous growth with pollution externalities
We analyze the effect of non-constant discounting on economic growth and social welfare in an endogenous growth model with pollution externalities. For ti...
BibTeX reference
Climate change is one of the greatest environmental challenges facing our planet in the foreseeable future, yet, despite international environmental agreemen...
BibTeX reference
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...
BibTeX reference
This study presents a production scheduling optimization method for a mining complex, which provides a flexible long-term plan for future investments and ope...
BibTeX reference
This work studies the strategic impact of a region's investment in adaptation measures on the equilibrium outcomes of a transboundary pollution dynamic gam...
BibTeX referenceNumerical methods for stochastic dynamic programming with application to hydropower optimization
Stochastic Dynamic Programming (SDP) is a powerful approach applicable to nonconvex and stochastic stagewise problems. We investigate the impact of the form...
BibTeX reference
The calibration of hydrological models is here formulated as a Blackbox optimization problem where the only information available to the optimization algorit...
BibTeX reference
A performance-based mechanism as a support for an environmental protection law is proposed to promote product recovery and to subside the pollution caused by...
BibTeX referenceAre ECVs breaking even? Competitiveness of electric commercial vehicles in retail logistics
In this paper, we evaluate the competitiveness of electric commercial vehicle (ECV) in medium-duty mid-haul logistics for a specific case study. This is done...
