A manufacturing process is a stochastic process which is expected to keep a consistent quality level. However, unexpected events (assignable causes) can break the consistency and move the mean of quality characteristic to an unknown level at an unknown time. Control charts of statistical process control (SPC) are used to monitor the process and signal alarms if the process change does happen. In this talk, designs and properties of control charts that commonly used by quality engineers will be discussed. Meanwhile, it is noticed that control chart alone does not provide control actions or suggestions for correcting the process change. Several process adjustment strategies will be presented in this talk. The small-sample performance of integrating process adjustments with control charts will be compared through Monte Carlo simulation study.
