摘要

In accordance with the ISO Guide to the Expression of Uncertainty in Measurement (GUM), the modeling of the measurement is a key element of the evaluation of measurement uncertainty. It is the aim of the modeling procedure to mathematically establish the relationship between the measurand and all input quantities, which may contribute to the uncertainty associated with the measurement result. This relationship serves as a basis for the uncertainty propagation as well as for computer-aided uncertainty determination. Since neither the GUM nor other relevant uncertainty documents provide any guidance on the systematic modeling of measurements, it appears to be the most difficult problem of modern uncertainty evaluation.
