Optimization in Networks: Modeling, Algorithms and Applications

Abstract

Network models provide insights to tackle a variety of problems in such diverse areas as production, logistics, routing, location, among others. Network structures are largely present in many industrial and service contexts like supply chain, transportation, communication and natural systems. Despite the fundamental developments achieved since the early days of Operations Research, the community still faces many challenges in the field, ranging from modeling paradigms for hard problems to the design and experimental evaluation of efficient methods and algorithms. Given its importance and applicability, this Special Issue of Pesquisa Operacional aims at presenting recent contributions inspired by real-life network optimization problems. The result is this issue that features the following eight papers: 1-Araujo et al. propose an alternative method to solve the multi-terminal maximum flow problem when the given network has cut nodes.
