Abstract
Virtual experiments have become increasingly important in metrology and industry. Combined with Monte Carlo methods, they are also employed for uncertainty evaluation. However, the modeling principles underlying the Guide to the Expression of Uncertainty in Measurement (GUM) generally differ from the concepts of a typical virtual experiment. We discuss these conceptual differences and exemplify how they can affect resulting uncertainties. We also show that for certain linear models virtual experiments can nevertheless be used to determine measurement uncertainties in line with the GUM.
