Short- and medium-term optimization of underground mine planning using constraints programming
For the past few years, the mining industry has seen a lot of operational changes. Digitalization and automation of many processes have paved the way for an ...
BibTeX reference
Over the last decade, geological uncertainty, its effects on long-term mine planning and methods for related risk management have been studied. However, th...

A mining complex can include multiple mines, stockpiles, waste dumps and processing facilities. Traditional optimization approaches are often based on sequ...
BibTeX reference
Mining complexes are value chains where extracted material from different mines is transformed into sellable products through a set of processing streams. ...

We consider the problem of efficiently managing a fishery where pollution externalities are present. The open-access bionomic model is analyzed in an \(n\)
...
In the recent years, the development of new algorithms for multiobjective optimization has considerably grown. A large number of performance indicators has...

In this paper, we study the problem of responsibility sharing for product recovery, and its relation to the design of Extended Producer Responsibility (EPR) ...
BibTeX reference
A new solution approach is developed herein to address the topic of multi-product open-pit mine production scheduling with multi-element uncertainty. The m...

This paper addresses the problem of distributing uniformly infrared radiative energy intercepted by a thermoplastic sheet surface during the infrared radiati...
BibTeX reference
We study an integrated process configuration, lot-sizing, and scheduling problem, which appears in a real production environment in the packaging industry. P...
BibTeX referenceEquilibria in a two-species fishery
In this paper, we consider a two-species fishery model where the species can have different biological interactions, namely, competitive, symbiotic or prey...
BibTeX reference
There has been a lot of interest recently on the energy efficiency and environmental impact of wireless networks. Given that the base stations are the netw...
BibTeX referenceA PCA-based approximation scheme for combinatorial optimization with uncertain and correlated data
This paper addresses combinatorial optimization problems under uncertain and correlated data where the mean-covariance information of the random data is assu...
BibTeX reference
We address a three-level lot sizing and replenishment problem with a distribution structure (3LSPD), which is an extension of the one-warehouse multi-retaile...
BibTeX reference
We consider an integrated planning problem that combines production, inventory and inbound transportation decisions in a context where several suppliers each...
BibTeX reference
This article describes a new model aiming at optimizing short- and medium-term underground mine scheduling. The complexity of the problem to solve and the fr...
BibTeX reference
The Time Window Assignment Vehicle Routing Problem (TWAVRP) is the problem of assigning time windows for delivery before demand volume becomes known. This i...
