Hub Location with Protection under Link Failures
Y. Hinojosa Bergillos, V. Blanco, E. Fernández
In this paper we provide two different mathematical programming models to construct hub backbone networks protected under hub links disruptions. Both models consider the minimization of the set-up costs of the activated hubs and inter-hub edges plus the expected value of the routing costs of the original and alternative paths and force the original routing path of each commodity to contain at most one inter-hub arc. The first model imposes that the alternative routing path also contains at most one inter-hub arc and builds it explicitly. The second model is more flexible, in the sense that it allows that arbitrarily large sequences of inter-hub arcs are used in the alternative routing paths, although alternative paths are not built explicitly. We report the results of an extensive battery of experiments to analyse the performance of the two proposed models, to derive managerial insights and to evaluate the cost required to design a robust backbone network under hub-links failure.

Visit Alhambra
Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
