Fuzzy Control Chart A Better Alternative for Shewhart Average Chart

Quality & Quantity, 2006
This paper through a real illustrative example and a power test shows that designing a fuzzy control chart for process average of a continuous (variable) quality characteristic with a warning line is a better alternative to Shewhart \(\bar{X}\) chart in many respects, like providing better neural view to inspectors, offering different strategic options

ADAPTIVE SAMPLING ENHANCEMENTS FOR SHEWHART CONTROL CHARTS

IIE Transactions, 1993
Adaptive sampling is an enhancement to a classical statistical process control scheme in which the time between samples from the process is varied based on the available information. Unlike the classical Shewhart control schemes, the performance of an adaptive sampling scheme for detecting a process which is off-target before the First observation is ...

A unified approach to adaptive Shewhart control charts

Communications in Statistics - Theory and Methods, 2016
ABSTRACTA completely adaptive (CA) chart, that is, an chart in which sampling interval, sample size, control limits, and warning limits are all adaptive and switch between two values, is explored. The exact expressions for the statistical and operational performance measures for this chart are derived.
