This paper presents a metaheuristic solution to the optimization of open pit long-term production scheduling with a stockpile and geological uncertainty. The...
BibTeX reference
The use of spatial high-order statistics has been previously proposed as an alternative to introduce richer information about complex spatial patterns in the...
BibTeX reference
The production scheduling of an open pit mine determines the optimal extraction sequencing that significantly impacts a mine's life as well as net present va...
BibTeX reference
Mining complexes contain multiple sequential activities that are strongly interrelated. Extracting the material from different sources may be seen as the fir...
BibTeX reference
We propose a new large scale optimization model, named TS_LAP, for the locomotive assignment problem (LAP), which relies on train strings or consist travel p...
BibTeX reference
The buffer sizing problem in unreliable production lines is a complex combinatorial optimization problem. In the formulation of the problem, the system consi...
BibTeX reference
While there has been a surge of articles on convergence diagnostic tools for MCMC on continuous stationary distributions and ordinal state spaces, Bayesian c...
BibTeX reference
We investigate geoengineering as a possible substitute for mitigation and adaptation measures to reduce damages from climate change. With the help of an inte...
BibTeX reference
Air traffic in Europe is predicted to increase considerably over the next decades. In this context, we present a study of the interactions between the costs...
BibTeX reference
The improved primal simplex (IPS) was recently developed by Elhalaloui et al. to take advantage of degeneracy when solving linear programs with the primal si...
BibTeX reference
We consider a dynamic closed-loop supply chain made up of one manufacturer and one retailer, with both players investing in a product recovery program to inc...
BibTeX reference
We revisit the relationship between market power and firms' investment incentives in a noncooperative differential oligopoly game in which firms sell diffe...
BibTeX referenceShift scheduling under stochastic demand
Shift scheduling when the demand for employees is stochastic is usually done in two steps. Since employees need to know their shifts before the demand is kno...
BibTeX referenceA semidefinite optimization-based approach for global optimization of multi-row facility layout
This paper is concerned with the Multi-Row Facility Layout Problem. Given a set of rectangular facilities, a fixed number of rows, and weights for each pair ...
BibTeX reference
We introduce learning in a dynamic game of international pollution, with ecological uncertainty. We characterize and compare the feedback non-cooperative emi...
BibTeX reference
This paper focuses on the resolution of the capacitated minimum cost flow problem on a network comprising <i>n</i> nodes and <i>m</i> arcs. We present a met...
BibTeX reference
Remote communities are typically isolated from the main electricity grid and require local generation, most often relying on expensive resources (especially ...
BibTeX reference
Simulation-and-regression algorithms have become a standard tool for solving dynamic programs in many areas, in particular financial engineering and computat...
BibTeX referenceComparison of mixed integer linear models for fuel-optimal air conflict resolution with recovery
Any significant increase in current levels of air traffic will need the support of efficient decision-aid tools. One of the tasks of air traffic management i...
BibTeX reference
Scheduling production in open-pit mines is characterized by uncertainty about the metal content of the orebody (the reserve) and leads to a complex large-sca...
