Single • Control Chart Scheme

Abstract

States that, under certain circumstances, a single • control chart with tightened control limits may be more effective for detecting process shifts than the combination of • and s control charts, while the type I error can be kept at the same level. A computer program is developed to decide whether the single • chart scheme can be applied to a given process control.
