The sound tolerance interval–based method and two Pp–based approximations are compared on the proportion of nonconforming parts. As output distribution of the process, one possible model is examined here: two sources of variations are in a one‐way structure. It was found that the uncertainty of variance components estimates plays the major role in the goodness of the three calculation methods.

存在两个变异源时的过程能力指数,公差区间法

基于声音容差区间的方法和两种基于 Pp 的近似值在不合格零件的比例上进行了比较。作为过程的输出分布,这里检查了一个可能的模型:两个变化源处于单向结构中。发现方差分量估计的不确定性在三种计算方法的优劣中起主要作用。
