本文讨论了当质量特性服从正态分布时，上单侧控制图和EWMA控制图的游程长度的某些随机性质。我们看看这两个图表的表现，在过程中的平均值和标准差的变化，并在他们的能力，以检测这些后者的变化，并给出误导性的信号。
In this paper we shall discuss certain stochastic properties of the run length of upper one-sided andEWMA control charts for the process mean when the quality characteristic is normally distributed. We look at the performance of these two charts in the presence of shifts in the process mean and the standard deviation, and at their ability to detect these latter shifts and to give misleading signals.
