This paper presents a metaheuristic solution to the optimization of open pit long-term production scheduling with a stockpile and geological uncertainty. The...

The use of spatial high-order statistics has been previously proposed as an alternative to introduce richer information about complex spatial patterns in the...

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...

Mining complexes contain multiple sequential activities that are strongly interrelated. Extracting the material from different sources may be seen as the fir...

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...

The buffer sizing problem in unreliable production lines is a complex combinatorial optimization problem. In the formulation of the problem, the system consi...

While there has been a surge of articles on convergence diagnostic tools for MCMC on continuous stationary distributions and ordinal state spaces, Bayesian c...

We investigate geoengineering as a possible substitute for mitigation and adaptation measures to reduce damages from climate change. With the help of an inte...

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...

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...

Nous considérons une chaîne d'approvisionnement fermée composée d'un fabricant et d'un détaillant dans un contexte dynamique. Les joueurs investissent dans ...

On reconsidère la relation entre le pouvoir de marché et les incitatifs à l'investissement par des firmes. On fait appel à un jeu différentiel avec des firm...

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...

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 ...

On considère un jeu dynamique de contrôle de pollution en présence d'incertitude écologique. On caractérise et on compare les stratégies d'équilibres en rétr...

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...

Les communautés éloignées sont typiquement isolées des réseaux de production, transport et distribution d'électricité. C'est ainsi qu'elles doivent compter s...

Les algorithmes de simulation et régression sont désormais un outil de base dans plusieurs domaines d'application de la programmation dynamique, notamment en...

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...

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...
