Abstract:Aiming at solving the problem of subjectively determining the optimal level during the fuzzy evaluation to the expanded uncertainty of measured result, the paper offered a kind of theoretical determination approach based on the theory distribution of measured data and fuzzy mathematics. The simulation result showed that the expanded uncertainty which was calculated on the basis of the optimal level determined by the approach has higher accuracy.
Keywords:Expanded uncertainty Measured data Fuzzy mathematics Optimal level Normal distribution Triangle distribution
