RESIDUAL ANALYSIS WITH SHEWHART CONTROL CHARTS
Quality Engineering, 1991We show that the conditions for process stability are equivalent to the conditions for the error terms of a valid regression model (one in which the least squares estimators are unbiased and have minimum variance among all unbiased estimators). By viewi..

1979
The concept of a control chart was evolved by Dr. Shewhart in America in 1924 — the initial development in Britain being mainly by Dr. Dudding and W. Jennett. Dr. Shewhart suggested that the control chart should have three main objectives.

About Shewhart control charts to monitor the Weibull mean
Quality and Reliability Engineering International, 2019AbstractIn this paper, a new reparametrization expressed in terms of the process mean for Weibull distribution is studied; thus, the monitoring of the process mean can be made directly. Additionally, we call attention that the asymptotic control limits for control chart by central limit theorem (CLT) may lead to a serious erroneous decision ...

Shewhart Control Charts for Monitoring Reliability with Weibull Lifetimes
Quality and Reliability Engineering International, 2014In this paper, we present Shewhart‐type and S2 control charts for monitoring individual or joint shifts in the scale and shape parameters of a Weibull distributed process. The advantage of this method is its ease of use and flexibility for the case where the process distribution is Weibull, although the method can be applied to any distribution.

Fuzzy Control Chart A Better Alternative for Shewhart Average Chart
Quality & Quantity, 2006This 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, 1993Adaptive 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, 2016ABSTRACTA 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.
