We have studied power functions for several control rules by use of a computer simulation program. These power functions show the relationship between the probability for rejection and the size of the analytical errors that are to be detected. They allow some assessment of the quality available from present statistical control systems and provide some guidance in the selection of control rules and numbers of control observations when new control systems are designed.
我们通过使用计算机模拟程序研究了几种控制规则的幂函数。这些幂函数显示了拒绝概率与待检测分析误差大小之间的关系。它们有助于对现有统计控制系统的质量进行一些评估，并在设计新的控制系统时为控制规则的选择和控制观测次数提供一些指导。
