XVI Latin-Ibero-American Conference on Operations Research/XLIV Brazilian Symposium on Operations Research (CLAIO/SBPO - 2012)

Abstract

. These events have been a great opportunity for researchers and practitioners in the region to further exchange their experiences, to contribute, establish, and deepen their ties and to help young undergraduate and graduate students in their professional development.This special issue was negotiated by the organizers of the CLAIO/SBPO -2012 that decided to bring out papers presented at the conference, in full, in a good scientific journal of the area. They contacted the Editor in Chief of Pesquisa Operacional and SOBRAPO that agreed with the idea. A public announcement on the special issue was made and the decision to submit a complete version of the papers presented at the conference was left to authors. All the manuscripts received were processed according to the norms and the rigor of publication of Pesquisa Operacional.The result is this issue that features the following nine papers: 1 -Canale et al. deal with a problem related to the design of multilayer telecommunication networks;2 -Martello presents two-dimensional packing problems that arise in an application in mobile telecommunication systems; 3 -Alves et al. present a metric based on local variability, which legitimizes the use of the ellipsoidal frontier model with the choice of distribution of eccentricities with the least variability in the data;
