Stochastic long-term production scheduling of the LabMag iron ore deposit in Labrador, Canada
A long-term production schedule for the LabMag iron ore deposit in northern Québec, Canada is derived using stochastic integer programming. The optimization ...
BibTeX reference
Short-term mine production scheduling optimization is developed as a single formulation where mining considerations, production constraints, uncertainty in t...
BibTeX reference
This paper presents a new mathematical formulation to address mine production scheduling with multiple processing streams, under mineral supply uncertainty, ...
BibTeX reference
A two-stage stochastic mixed integer non-linear program is formulated for a mining complex to optimize strategic and tactical plans. The objective is to find...
BibTeX referenceJoint simulation of correlated variables using high-order spatial statistics for orebody modeling
Geostatistical simulation techniques are used to quantify uncertainty of spatial attributes of interest describing mineral deposits, petroleum reservoirs, hy...
BibTeX referenceGlobally optimizing open-pit and underground mining operations under geological uncertainty
A method that optimizes mining complexes that are comprised of multiple processing destinations, open pits and underground operations is presented. Mining, b...
BibTeX reference
Previous research related to the optimization of mining operations has predominantly focused on generating a life-of-mine production schedule that maximizes ...
BibTeX reference
In this paper, we propose an empirical study of the centrality of actors in network. The data was collected among publicly available information of the boa...
BibTeX reference
In this paper, the first steps toward the use of the Variable Neighborhood Search metaheuristic are explained. The method is presented step by step using an...
BibTeX reference
We investigate the derivation of disjunctive conic cuts for mixed integer second order cone optimization (MISOCO). These conic cuts characterize the co...
BibTeX referenceMultilevel hybrid method for solving buffer sizing and inspection stations allocation problems
This paper develops an efficient method to solve a typical combinatorial optimization problem that is frequently encountered when designing high levels of pr...
BibTeX reference
This paper introduces a new primal algorithm for solving a linear program LP. In this algorithm, a pricing problem, namely a linear fractional program, is ...
BibTeX reference
An artificial olfaction called electronic nose (e-nose) relies on an array of gas sensors with the capability of mimicking the human sense of smell. Applying...
BibTeX reference
This paper investigates the dynamic pricing strategies of firms selling complementary products in a marketing channel. The problem is modelled as a non-coo...
BibTeX reference
In this paper, we summarize some properties of the Cartesian product of graphs related to degree and distance-based invariants. Then, we investigate how mu...
BibTeX referenceUse of a biobjective direct search algorithm in the process design of material science applications
This work describes the application of a direct search method to the optimization of problems of real industrial interest, namely three new material scien...
BibTeX reference
The effective management of call centers is a challenging task mainly because managers are consistently facing considerable uncertainty. Among important sour...
BibTeX reference
We propose a method to build trees and forests when the response is a non-homogeneous Poisson process with excess zeros, based on two forests. The first one...
BibTeX reference
The log-rank test is commonly used as the split function in many commonly used survival trees and forests algorithms. However, the log-rank test may have a...
BibTeX reference
Simulation-and-regression methods have been recently proposed to solve multi-period, dynamic portfolio choice problems. In the constant relative risk aver...
