统计过程控制（Statistical Process Control，SPC）是一种利用统计学原理来监控和控制生产过程的方法。其核心目的是通过实时监控生产过程的关键质量参数，确保生产过程的稳定性和一致性，从而提高产品质量，减少浪费，并优化生产效率。一、关键组成 1. 控制图（Control Charts）: 控制图是一种图形工具，用于显示生产过程中...
All statistical process control charts plot data (or a statistic calculated from data) versus time, with control limits designed to alert the analyst to events beyond normal sampling variability.Our STATGRAPHICS Centurion SPC software packages provide one of the most extensive collection of control ...
The most critical assumption made concerning statistical process control (SPC) charts, i.e., Shewhart Control Charts, is that of data independence from one observation to the next (not autocorrelated) [1, 2]. The second assumption is that the individual observations are approximately normally distr...

Statistical Process Control Charts (统计过程控制图).pdf,Deciding which Control Chart to Use Statistical Process Control Charts In contrast to the run chart there are numerous ways to construct control charts. The decision of which to use hinges on the
First, control charts demonstrate how consistently process is performing, and whether you should, or should not, attempt to adjust it. Next, the statistical process control chart compares the process performance to standard pharmaceutical requirements, providing a process capability index as an ongoing,...

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. ...
