The Computational Intelligence Research group of UNINOVA (CA3) main mission is to actively participate in applied research, supported by projects, by defining new concepts, methods and algorithms capable of solving real-world problems
Intelligent decision making
The growing complexity of real decision making problems requires handling both quantitative and qualitative information. The major challenges of rationalizing decision processes are how to handle heterogeneous information, its intrinsic imprecision/uncertainty and its dynamic nature. The capability of representing and handling imprecise concepts is essential in today's information society, due to the large quantities of information available for decision making.

This research is mainly focused on concepts, methods and algorithms for solving multicriteria decision making and dynamic decision making problems and developing applications with special emphasis in the Space domain.
