We consider the problem of estimating the density of a random variable X
which is the output of a simulation model.
We show how an unbiased density ...
We study quasi-Monte Carlo (QMC) integration of smooth functions defined over the multi-dimensional unit cube. Inspired by a recent work of Pan and Owen, we ...

The Generator Maintenance Scheduling Problem (GMSP) is a problem that combines a hydropower optimization problem with a scheduling problem. Both problems are...
BibTeX reference
In the Weighted Fair Sequences Problem (WFSP), one aims to schedule a set of tasks or activities so that the maximum product between the largest temporal dis...

Engineering design is often faced with uncertainties, making it difficult to determine an optimal design. In an unconstrained context, this amounts to choose...
BibTeX referenceLearning to schedule heuristics for the simultaneous stochastic optimization of mining complexes
The simultaneous stochastic optimization of mining complexes (SSOMC) is a large-scale stochastic combinatorial optimization problem that simultaneously manag...

The problem of portfolio management represents an important and challenging class of dynamic decision making problems, where rebalancing decisions need to be...
BibTeX referenceData-driven optimization with distributionally robust second-order stochastic dominance constraints
Optimization with stochastic dominance constraints has recently received an increasing amount of attention in the quantitative risk management literature. In...
BibTeX reference
Within the context of optimization under uncertainty, a well-known alternative to minimizing expected value or the worst-case scenario consists in minimizing...
BibTeX reference
With the ongoing energy transition, electric power and energy systems are becoming increasingly multi-dimensional and complex with higher levels of uncertain...
BibTeX reference
Production yield can be highly volatile and uncertain, especially in industries where exogenous and environmental factors such as the climate or raw material...
BibTeX reference
This paper studies a stochastic variant of the vehicle routing problem (VRP) where both customer locations and demands are uncertain. In particular, potentia...
BibTeX reference
This paper introduces the consistent production routing problem in a setting with multiple plants and products. The problem consists in finding minimum-cost ...
BibTeX referenceAdaptive simultaneous stochastic optimization of mining complexes: Where is the value coming from?
This paper aims to identify the sources of value created in the strategic plan of a mining complex when the adaptive simultaneous stochastic optimization of ...
BibTeX referenceStochastic stope design optimization under grade uncertainty and dynamic development costs
Stope design optimization defines mineable three-dimensional material volumes to be extracted from a mineral deposit, aiming to maximize cashflows subject ...

The geometallurgical models that predicting the throughput/comminution performance of the a processing plant often rely on rock hardness models, which are ba...
BibTeX reference
This work is in the context of blackbox optimization where the functions defining the problem are expensive to evaluate and where no derivatives are availabl...
BibTeX referenceIntegrating learning and explicit model predictive control for unit commitment in microgrids
In this paper, we apply flexibility-based operational planning method to microgrid (MG) unit commitment (UC). The problem is formulated based on model predi...
