The purpose of this paper is to provide an overview and our perspective of recent research
and applications of statistical process monitoring. The focus is on work done over the past …

The performance of the Shewhart X̄ control chart with estimated in-control parameters has
been discussed a number of times in the literature. Previous studies showed that at least …

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 …

An overview of monitoring schemes from a class called generally weighted moving average
(GWMA) is provided. A GWMA scheme is an extended version of the exponentially weighted …

We provide an overview and discussion of some issues and guidelines related to monitoring
univariate processes with control charts. We offer some advice to practitioners to help them …

In the world of business, quality improvement is of high importance for the manufacturing
industries. Statistical process control via control charts provides an online monitoring of the …

A unique approach to understanding the foundations of statistical quality control with a focus
on the latest developments in nonparametric control charting methodologies Statistical …

The impact of parameter estimation on control charts has been studied with great interest in
the recent literature. The estimated control limits affect chart performance, often negatively …

We evaluate the in-control performance of the S 2 control chart with estimated parameters
conditional on the Phase I sample. Simulation results indicate no realistic amount of Phase I …

The performance of control charts can be adversely affected when based on parameter
estimates instead of known in‐control parameters. Several studies have shown that a large …
