This longitudinal quantitative study investigates how organizational structure and the external environment impact VC firm survival. It examines how macroeco...

We develop customer delay predictors for multi-skill call centers that take as inputs the queueing state upon arrival and the waiting time of the last custom...

Recent contributions to the financial econometrics literature exploit high-frequency (HF) data to improve models for daily asset returns. This paper propose...

In this article, we tackle the conflict resolution problem using a new variant of the minimum weight maximum clique model. The problem consists in identifyi...

We consider a multi-agent system with linear stochastic individual dynamics, and individual linear quadratic ergodic cost functions. The agents partially o...

The paper shows that among all equilateral polygons with a given number of sides and the same diameter, the regular polygon has the maximal area.

The optimization of mine complexes and related value chains is a challenging problem due to the simultaneous presence of a highly-dimensional decision space,...

This paper addresses the optimization of mineral supply chain operations under metal and material type uncertainties. A mathematical model to simultaneously ...

This paper presents a mixed integer programming formulation dealing with the effective minimisation of risk incurred when optimizing mining production rates ...

Traditional geostatistical simulation methods assume that the first two order statistics are sufficient to model mineral deposits. However, these methods are...

Modeling and assessing spatial uncertainty of mineral deposits is critical for capital investments in mining projects. However, traditional approaches for mo...

A long-term production schedule for the LabMag iron ore deposit in northern Québec, Canada is derived using stochastic integer programming. The optimization ...

Short-term mine production scheduling optimization is developed as a single formulation where mining considerations, production constraints, uncertainty in t...

This paper presents a new mathematical formulation to address mine production scheduling with multiple processing streams, under mineral supply uncertainty, ...

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...

Geostatistical simulation techniques are used to quantify uncertainty of spatial attributes of interest describing mineral deposits, petroleum reservoirs, hy...

A method that optimizes mining complexes that are comprised of multiple processing destinations, open pits and underground operations is presented. Mining, b...

Previous research related to the optimization of mining operations has predominantly focused on generating a life-of-mine production schedule that maximizes ...

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...

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...
