WebA deterministic method for performing an uncertainty analysis is applied to the results of a system of three codes previously analyzed by purely statistical means. This new … WebAnalysis (SA) process. SA allows the study of how uncertainty in the output of a model can be apportioned to di erent sources of uncertainty in the model input [51]. It may be used to determine the input variables that contribute the most to an output behavior, and the non-in uential inputs, or to ascertain some interaction e ects within the model.
