Control charts using minima instead of averages [PDF]
, 2006 Traditional control charts are commonly based on the averages of the inspected groups of observations. It turns out to be quite worthwhile to consider alternative approaches.

A Spatiotemporal Scheme for Process Control Using Image Analysis of Speckle Patterns
Quality and Reliability Engineering International, Volume 41, Issue 5, Page 1773-1788, July 2025.ABSTRACT Conventional image‐based process control schemes require distinct, detectable features (e.g., edges or textures). In the absence of such features, current methods fail or require additional preprocessing. They are also prone to false detections from random noise, dirt, or scratches on the surface.

Distribution-Free Control Charts Based on Multiple Runs: Advances and Applications in Supply Chain Management [PDF]
International Journal of Mathematical, Engineering and Management SciencesIn this article, we improve the behavior of nonparametric Shewhart-type control charts, which employ order statistics and multiple runs-type rules. The proposed class of monitoring schemes includes some existing control charts.

Monitoring Reliability for Three-Parameter Frechet Distribution Using Control Charts
IEEE Access, 2020 Control Charts for attributes have been widely adopted for examining the fraction non-conforming or non-conformities in a process. However, Shewhart control charts may face some practical problems when the process fraction of non-conformities is very low.

Outliers Detection Models in Shewhart Control Charts
Mathematics, 2020 Shewhart control charts with estimated control limits are widely used in practice. However, the estimated control limits are often affected by phase-I estimation errors.

Control Charts for the Lognormal Distribution [PDF]
Control Charts are the main tools of Statistical Process Control. They are used for deciding whether a process is statistically stable or not. Much theory and many applications have been developed for the Gaussian (Normal) distribution in this area ...
