Abstract:
Nowadays computational predictive models are standard tools for analysis of complex systems and phenomena. However, any computational model may be uncertain with respect to the system/phenomenon of interest, due to variabilities on its parameters and, mainly, because of assumptions made on its conception that may not be in agreement with the reality. The first source of uncertainty is inherent to measurements limitations, imperfections in manufacturing process, material and geometric variabilities, etc. Meanwhile, the second type is essentially due to lack of knowledge about the underlying governing laws. Uncertainty Quantification (UQ) can be thought of as a multi-disciplinary area that deals with quantitative characterization and reduction of uncertainties in applications, which is extremely necessary to give robustness to computational forecasts. The lectures will cover the basic vocabulary of UQ, the possible approaches to modelling uncertainties, the main techniques for uncertainty propagation. Basic topics of probability and statistics will be reviewed. Computer activities will be developed in parallel to theoretical expositions, as a way to give a hands-on tone to the course.
