The K-MedianPlex problem: addressing locational complexity in network design
D. Ruiz-Hernandez, J. M. PINAR PÉREZ
This work addresses the problem of locational complexity and its inclusion in network design problems. We define “locational complexity” as the intricated set of interactions and decisions that emanates from a company's territorial strategy. The rationale is that an ever-growing number of facilities and a constant expansion into new markets tends to introduce hidden costs that hinder the capacity of the company to generate profits. Earlier work of these authors, reveals that standard location problems tend to generate oversized networks, inducing what other authors have called “an addition to growth”.
Locational complexity is introduced in a standard K-Median formulation by using an entropy-based measure for supply chain structural complexity. This results in a highly combinatorial and nonlinear problem referred to as the K-MedianPlex problem. A maximum-ascent greedy heuristic is proposed for solving large instances of the problem.

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.
