Relational mathematics, as it is studied in mathematical economics and social choice theory, provides a rich and general framework and appears to to be a natural and direct way to paraphrase optimization goals, to represent user preferences, to justify fairness criterions, or to valuate utility. In this talk, we will focus on the specific application aspects of formal relations in network design and control problems. The talk will have three main parts. In the first part, we want to present a suite of new relations that are able to represent fairness as mediator between user preference and network infrastructure dominance. Starting with the "classical" fairness relations maxmin fairness, proportional fairness and lexmin, we can recover their mutual relationships and their design flexibility in order to define further relations, with regard to e.g. multi-fairness, ordered fairness, self-weighted fairness, grouped fairness, and fuzzy fairness. In the second part, we want to illustrate and demonstrate the application of these relations for basic network design and control problems, esp. routing path selection, congestion control, wireless channel allocation, and relaying. The third part is concerned with the tractability of related problems, and we will present generic approaches by meta-heuristic algorithms, esp. algorithms obtained from suitable modifications of evolutionary multi-objective optimization algorithms that can cope with a broad spectrum of occurring search and approximation problems. We will conclude with the outlook on a concept of generalized optimization.

Short Bio:

Mario Köppen was born in 1964. He studied physics at the Humboldt-University of Berlin and received his master degree in solid state physics in 1991. Afterwards, he worked as scientific assistant at the Central Institute for Cybernetics and Information Processing in Berlin and changed his main research interests to image processing and neural networks. From 1992 to 2006, he was working with the Fraunhofer Institute for Production Systems and Design Technology. He continued his works on the industrial applications of image processing, pattern recognition, and soft computing, esp. evolutionary computation. During this period, he achieved the doctoral degree at the Technical University Berlin with his thesis works: "Development of an intelligent image processing system by using soft computing" with honors. He has published around 100 peer-reviewed papers in conference proceedings, journals and books and was active in the organization of various conferences as chair or member of the program committee, incl. the WSC on-line conference series on Soft Computing in Industrial Applications, and the HIS conference series on Hybrid Intelligent Systems. He is founding member of the World Federation of Soft Computing, and also member of the editorial board of the Applied Soft Computing journal, the Intl. Journal on Hybrid Intelligent Systems and the Intl. Journal on Computational Intelligence Reserach. In 2006, he became JSPS fellow at the Kyushu Institute of Technology in Japan, and in 2008 Professor at the Network Design and Reserach Center (NDRC) of the Kyushu Institute of Technology, where he is conducting now research in the fields of multi-objective optimization, digital convergence and multimodal content management.

Innovation is the way through for the humans to improve its life, since we left the trees. And this is the way still: no innovation succeeds without improve our lives. Time ago, you could get a "barony" from the king; today, the power you can get depends on the benefits you can provide to your customers. And this is not a forever's power: there are others working hard to offer greater benefits to the market, and get your chair.

And this is not a tale. Innovation, in terms of product, and even more in terms of productivity, is always behind the economic health of a company or a country. Forget erroneous ideas about workers costs and its impact on economic localization. We don't buy in China "work intensive products", we buy "their" more capital intensive products. In technical terms, we buy the products with the higher "relative" productivity. Holland exports potatoes and tomatoes, and Holland is not a cheap workers place. They also exports flowers, as the Colombian does. In both cases, flowers have the higher productivity in their respective countries.

So, let's welcome the good news: tomorrow is decided every day, and everybody is invited to participate innovating; the global competition starts at local level, with the "higher productivity companies" taking part of the champion league.

In this talk we will focus on innovation in the field of aerospace technology and will bring the experience of the Aerospace Research & Technology Center of Catalonia (CTAE) from several research and development projects on positioning and navigation.
