Nearly all my research activity has taken place in the frame Multiple Criteria Decision Making (MCDM), in the Reasearch Group on Multicriteria Decision Making of the University of Málaga.
Multiple Criteria Decision Making is the branch of Operational Research that studies the development and application of mathematical techniques for ading decision making processes. When the set of possible decisions can be mathemacally defined through a series of inequelities, and he criteria can take the form of objectives represented by functions, then we are facing a Multiobjective Programming problem.
The growing interest of the international scientific community in the problem of sustainability, together with its intrinsic multicriteria nature, made us start looking for applications in this field. Therefore, these are the main reserach themes of our group.
For further information about these topics, go to the group's webpage, by clicking on the logo, or to any of the links listed in the corresponding section.
My current research and interest topics are:
Interactive Mwhtods in Multiobjective Programming.
Multicriteria Techniques in Environmental Policy and Ecological Economy.
Desarrollo de algoritmos de resolución de problemas multiobjetivo.
Software development.
Meta-GP.
Real applications of multiobjective techniques in several fields:
- Electricity generation systems,
- Design of synthetic sustainability indicators,
- Portfolio selection.
