The inventory-routing problem (IRP) integrates two well-studied problems, namely, inventory management and vehicle routing. Given a set of customers to servi...

In many applications, such as metabolomics, data are composed of several continuous measurements of subjects (tissues) over multiple variables (metabolites)....

Constrained blackbox optimization is a difficult problem, with most approaches coming from the mathematical programming literature. The statistical literatur...

Blackbox optimization deals with situations in which the objective function and constraints are typically computed by launching a time-consuming computer ...

A preconditioned variant of the Golub and Kahan (1965) bidiagonalization process recently proposed by Arioli (2013) and Arioli and Orban (2013) allows us to ...

In this article, we propose a general framework for an algorithm derived from the primal simplex that guarantees a strict improvement in the objective after ...

The dust suppression of hauling roads in open-pit mines is done by periodically spraying water from a water truck. The objective of this article is to presen...

Finding communities in complex networks is a topic of much current research and has applications in many domains. On the one hand, criteria for doing so hav...

This paper presents the first direct implementation of the positive edge criterion using COIN-OR's CLP, where it has been combined with the Devex pivot rule....

In this paper, we suggest a new approach called the <i>return function</i> to deal with the determination of Bayesian-Nash equilibria in games of incomplet...

Commercial piracy and counterfeiting are widespread phenomena in different businesses, ranging from software and video games to luxury fashion products. Th...

The <b>VRPTW-ST</b> introduced by Errico et al. (2013) in the form of a chance-constrained model mainly differs from other vehicle routing problems with st...

Typical challenges of simulation-based design optimization include unavailable gradients and unreliable approximations thereof, expensive function evaluation...

Hybrid power systems for off-grid sites are commonly designed using simulation. Operating rules for the controller dispatch strategy are defined, and a sim...

This article describes the problem in which the edges of a network represent customers, and a quantity of material is delivered to them so that each one achi...

A dynamic global hedging procedure making use of futures contracts is developed for a retailer of the electricity market facing price, load and basis risk. S...

This paper introduces a joint planning and management optimization approach for cellular networks to limit energy consumption while guaranteeing QoS and mini...

The paper proposes a fundamental modeling and optimization framework for the planning of energy-aware wireless networks. The key idea is that, in order to p...

We propose an efficient heuristic method based on Space Partitioning (SP) and Tabu Search (TS) to solve the buffer sizing problem in unreliable production li...

An unreliable single part type transfer line with fixed inter machine buffer sizes is considered. In general, imperfect machines operating with imperfect raw...
