Abstract: Summary A new control chart based on the Fréchet distance for monitoring simultaneously the process level and spread is suggested. Our chart reveals interesting statistical properties: its behavior is comparable with traditional control charts if changes in process level only or changes in process spread only are observed, but it is much better than $$ \bar X$$ - S control chart under simultaneous disturbances in the process level and spread.
