Abstract

For the evaluation errors concerning the typical models for the measurement uncertainty evaluation, the verification method of uncertainties by computer simulation and experiment is proposed in this paper. Computer simulation is adopted to verify the uncertainties obtained through the model in Guide to the Expression of Uncertainty in Measurement, gray evaluation model of the standard uncertainty, and fuzzy evaluation model of the expanded uncertainty. Experimental facility is also designed to verify the measurement uncertainties. Through experiments, the verifications are conducted on the measurement result estimations, expanded uncertainties, coverage probabilities and dispersion range of measurement results obtained through fuzzy evaluation model and the model in Guide to the Expression of Uncertainty in Measurement. As is demonstrated through simulation and experimental results, the measurement uncertainty verification methods proposed in this paper is feasible.
