每种基于测量的合格控制方法都存在不确定性，这会扭曲决策。在传统的合格控制方法中，这种不确定性是观察到的特性偏差的固有部分；然而，真实产品特性的分布可能与测量不确定度的分布不同，从而掩盖了真实的合格或不合格。如果这种不确定性很高和/或与决策错误相关的后果很严重，则特别需要说明和考虑这种不确定性。本文研究了与决策结果相关的成本结构的影响以及测量不确定性分布的偏度和峰度。所提出的方法可以指定何时以及如何考虑测量不确定性，以增加与决策相关的预期利润。
Every conformity control method based on measurements is subject to uncertainty, which distorts the decision. In the traditional conformity control approaches, this uncertainty is an inherent part of the deviation of the observed characteristic; however, the distribution of the real product characteristic may differ from the distribution of measurement uncertainty, which obscures the real conformity or nonconformity. The specification and consideration of this uncertainty are particularly necessary if it is high and/or the consequences associated with the decision errors are severe. This paper studies the effects of the cost structure associated with the decision outcomes and the skewness and kurtosis of the measurement uncertainty distribution. The proposed method can specify when and how the measurement uncertainty should be taken into account to increase the expected profit associated with the decision.
