摘要

基于蒙特卡罗概率方法的数值方法被用来作为传统分析方法的一种有利的替代方法，用于评估通过数字处理采样输入数据获得的测量不确定性。该方法的正确性在单通道和多通道系统中都得到了验证。讨论了所提出方法可靠性的一些实际问题，并提出了适当设计的虚拟仪器，能够呈现测量结果及其不确定度。

Auto-evaluation of the uncertainty in virtual instruments

A numerical approach based on a Monte Carlo probabilistic method is used as an advantageous alternative to the traditional analytical methods for the evaluation of the uncertainty in measurements achieved by digitally processing sampled input data. The correctness of the approach is shown in the case of both single-channel and multi-channel systems. Some practical concerns about the reliability of the proposed methodology are discussed and suitably designed virtual instruments are presented that are able to present the measurement result along with its uncertainty.
