Uncertainties have two forms in SEA: lack of knowledge of inputs and model errors. FAST method is used to identify the effect of uncertain parameter on the variance. Both modelling uncertainties and input parameter variability can be handled. Applications are shown for sound transmission through plates and complex shells.
