摘要

在本文中，假设一个正常过程的均值是由CUSUM控制图监控的。当控制图触发一个信号并宣布过程已经失去控制时，就会启动一个搜索过程，以找到变化的时间和过程失去控制的原因。提出了几种寻找真(实)变点的方法(方案)。结果表明，基于时间点可能性的方案效果较好。

Finding True Change Point When a CUSUM Control Chart is Used

In this paper, it is assumed that the mean of a normal process is monitored by a CUSUM control chart. When the control chart triggers a signal and declares that the process has gone out of control, a search process is started to find the time of change and the causes of going the process out of control. Several methods (plans) for finding the true (real) change point is proposed. It is shown that the plans which are based on the likelihood of the points in time perform better.
