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...

Since the 1970's, several authors have studied the structure of the set partitioning polytope and proposed adaptations of the simplex algorithm that find an ...

Measurement systems studies are an integral part of most quality improvement processes. A desirable measurement system must produce repeatable and reprodu...

This work presents a variation of the elastic net penalization method. We propose applying a combined \(l\)₁ and \(l\)₂ norm pena...

Cognitive radio networks (CRNs) benefit from several features, such as decision-making, spectrum-awareness and reconfigurability over heterogeneous channels....

Cognitive radio networks (CRNs) benefit from several features, such as decision-making, spectrum-awareness and reconfigurability, which enable them to perfor...

Regarding the integration of services and applications, a requisite for the widely deployment of cognitive radio networks is the support of service different...

Recent data confirms that the power consumption of the ICT and of the Internet itself can no longer be ignored considering the increasing pervasiveness and...

A robust multi-period model is proposed to minimize the energy consumption of IP networks, while guaranteeing the satisfaction of uncertain traffic demands. ...

Despite the growing concern for the energy consumption of the Internet, green strategies for network and traffic management cannot undermine the quality and ...

In this paper we present JNetMan, a new Java framework for rapid development of network management solutions based on SNMP (Simple Network Management Protoco...

The analysis of networks and in particular the identification of communities, or clusters, is a topic of active research with application arising in many dom...
