A Successful Experience using Genetic Algorithms to Bridge the Digital Divide Pablo Cortes a, Jesus Munuzuri a, Jose Guadix a, Luis Onieva a a Organisation Engineering Depar'tment, School of Engineering. University of Sev.ille, Spain Abstract In this paper we describe a successful experience in the application of genetic algorithms. The Andalusian Regional Government was interested in defining strategies and taking measures promoting the development of the Information Society in the less favoured areas of the region. We collaborated developing a tool capable of evaluating the investment ratios that would be required to set up an optic fibre telecommunication network. Our proposal was a Decision Support System based on a genetic algorithm solutions' generator.
wide set of initiatives is the deployment of an optic fibre network reaching the less favoured areas of the Andalusian region. This initiative could give these communities the opportunity for achieving prosperity and progress. Furthermore, the access to information and communication technologies could contribute to the launching of small and medium-sized firms directly into the heart of regional, national and global markets. Even new advances as telemedicine could also provide access to up-to-date health and medical information to the most remote communities. But today, 'the Information Society access in these remote areas is unfortunately lamentable. In fact, the high cost of the telecommunication networks' infrastructure forces the companies to focus their efforts in the profitable society sectors. The initiative of the Andalusian Regional Government tries to bridge this difficulty. The General Directorate was especially interested in developing a tool capable of evaluating the investment levels that would be required to set up an optic fibre network And our collaboration was focused on it.
In troduction OR is a .field very much enhanced in the .last decades. Today OR is not only elegant mathematical methods but it includes a large variety of tools giving decision makers the option to deal with complex real life problems. Real life problems lead decision makers to take complex decisions: what can we do? Should we adapt reality to well-known models that we know how to solve? Or, should we adapt our models to reality even in the case that we would not know the way to solve them? We decided to go for the second option. Here we describe our experience trying to solve an extremely complex problem: the design of a universal high-speed telecommunication network across the Andalusian region, .in the south of Spain. The General Directorate for the Information Society in theJunta de Andalueta was interested in defining strategies and taking measures allowing the development of the Information Society around the entire region. One among a
The major difficulty that we found was the size of the network, because it had to connect all the municipalities of Andalusia in order to bridge the digital divide. We
