Effects of parameter estimation on control chart properties: a literature review

WA Jensen, LA Jones-Farmer, CW Champ… - Journal of Quality …, 2006 - Taylor & Francis
Control charts are powerful tools used to monitor the quality of processes. In practice, control
chart limits are often calculated using parameter estimates from an in-control Phase I …

The computation of average run length and average time to signal: an overview

Z Li, C Zou, Z Gong, Z Wang - Journal of Statistical Computation …, 2014 - Taylor & Francis
Control charts are widely used in industries to monitor a process for quality improvement.
Evaluation of the average run length (ARL) or average time to signal (ATS) plays an …

Monitoring general linear profiles using multivariate exponentially weighted moving average schemes

C Zou, F Tsung, Z Wang - Technometrics, 2007 - Taylor & Francis
We propose a statistical process control scheme that can be implemented in industrial
practice, in which the quality of a process can be characterized by a general linear profile …

Another look at the EWMA control chart with estimated parameters

NA Saleh, MA Mahmoud, LA Jones-Farmer… - Journal of Quality …, 2015 - Taylor & Francis
When in-control process parameters are estimated, Phase II control chart performance will
vary among practitioners due to the use of different Phase I data sets. The typical measure of …

A control chart based on a change-point model for monitoring linear profiles

C Zou, Y Zhang, Z Wang - IIE transactions, 2006 - Taylor & Francis
A control chart based on the change-point model is proposed that is able to monitor linear
profiles whose parameters are unknown but can be estimated from historical data. This chart …

A multivariate sign EWMA control chart

C Zou, F Tsung - Technometrics, 2011 - Taylor & Francis
Nonparametric control charts are useful in statistical process control (SPC) when there is a
lack of or limited knowledge about the underlying process distribution, especially when the …

Guaranteed conditional performance of control charts via bootstrap methods

A Gandy, JT Kvaløy - Scandinavian Journal of Statistics, 2013 - Wiley Online Library
To use control charts in practice, the in‐control state usually has to be estimated. This
estimation has a detrimental effect on the performance of control charts, which is often …

Statistical process control for shifts in mean or variance using a changepoint formulation

DM Hawkins, KD Zamba - Technometrics, 2005 - Taylor & Francis
Statistical process control (SPC) involves ongoing checks to ensure that neither the mean
nor the variability of the process readings has changed. Conventionally, this is done by pairs …

The run length distribution of the CUSUM with estimated parameters

LA Jones, CW Champ, SE Rigdon - Journal of Quality Technology, 2004 - Taylor & Francis
The CUSUM control chart is a popular method used to monitor the performance of
production processes. The performance of the CUSUM is generally evaluated with the …

Nonparametric CUSUM and EWMA control charts for detecting mean shifts

SY Li, LC Tang, SH Ng - Journal of Quality Technology, 2010 - Taylor & Francis
Nonparametric control charts are useful when the underlying process distribution is not likely
to be normal or is unknown. In this paper, we propose two nonparametric analogs of the …
