The training course presents an introduction to the COSSAN software, methods for uncertainty quantification, sensitivity and reliability analysis, as well as optimization, in presence of uncertainty.


Nowadays deterministic codes are quite sophisticated in terms of geometrical and mechanical modelling capabilities. However they usually neglect the important issue of inherent uncertainties in the model parameters, load and in the model itself. Without Uncertainty Quantification, only a single value of the results can be obtained, which does not reflect the actual possible range of the results due to uncertainties. The consideration of these uncertainties/variability increases essentially the quality of the results of the analysis and design of structures and systems. For these reasons, it is crucial to link deterministic codes with the advanced tools for the assessment of the uncertainty.

The COSSAN software provides a suit of general purpose package for realistic simulations taking into account the unavoidable uncertainties associated with models, e.g. in geometry, material properties, loads, etc. It allows to perform uncertainty quantification of any model (based on in-house solution or commercial packages). Thanks to its intuitive interface, it allows users to perform non-deterministic analysis without the need for excessive training.
