A critique of a variety of “memory-based” process monitoring methods
TL;DR: Many extensions and modifications have been made to standard process monitoring methods such as the exponentially weighted moving average (EWMA) chart and the cumulative sum (CUSUM) chart as mentioned in this paper , usually to put greater emphasis on past data and less weight on current and recent data.

A non-parametric exponentially weighted a moving average signed-rank chart for monitoring location
TL;DR: An extensive simulation study is done on the performance of the two-sided NPEWMA-SR chart including a detailed comparison with a number of existing control charts, including the traditional EWMA chart for subgroup averages and some nonparametric charts i.e. runs-rules enhanced Shewhart-type SR charts.

Nonparametric Control Charts: An Overview and Some Results
TL;DR: An overview of the literature on nonparametric or distribution-free control charts for univariate variables data is presented and connections to some areas of active research are made, such as sequential analysis, that are relevant to process control.
Journal ArticleDOI
Nonparametric quality control charts based on the sign statistic
TL;DR: In this article, a nonparametric control chart is presented for detecting changes in the process median (or mean), or changes in process variability when samples are taken at regular time intervals.

A Nonparametric Procedure for Process Control Based on Within-Group Ranking
Saad T. Bakir,Marion R. Reynolds +1 more
TL;DR: In this paper, a nonparametric procedure is developed for the problem of quickly detecting any shift in the mean of a sequence of observations from a specified control value, based on Wilcoxon signed-rank statistics where ranking is within groups.

Nonparametric (distribution-free) control charts: An updated overview and some results
TL;DR: Both univariate and multivariate nonparametric control charts are reviewed, unlike the past reviews, which did not include the multivariate charts, here they are reviewed.

A new nonparametric EWMA Sign Control Chart
TL;DR: A new nonparametric EWMA Sign Control Chart is proposed for monitoring and detecting possible deviation from the process target and the sampling properties of the new monitoring statistics are examined and the average run lengths of the proposed chart are derived for evaluating its performance.
