Statistical process control charts have recently been used for public health monitoring, predominantly in healthcare and hospital applications such as the surveillance of patient wait times or the frequency of surgical failures [e.g., 1-10]. Because the frequency of safety incidents like industrial ...
have been shown to be more efficient in detecting small shifts in the mean of a process. In particular, analyzing Average Run Length for CUSUM control charts shows that they are better than Shewhart control charts when it is desired to detect shifts in the mean that are 2 sigma or less. ...
Statistical process control charts have been in use for nearly 100 years. These charts are powerful tools, but it can be confusing to determine the appropriate data collection parameters. Understanding the trade-offs of the sampling frequency, subgroups, and plans is critical for controlling PCB man...
