New CUSUM and dual CUSUM mean charts

Quality and Reliability Engineering International, 2020
AbstractThe CUSUM (C) charts are well recognized as a potentially advanced process monitoring tools because of their sensitivity against small and moderate shifts. In this paper, we first improve the sensitivity of the Brownian motion–based C (BC) chart with an appropriate transformation, named new BC (NBC) chart, for monitoring moderate and large ...

New weighted adaptive CUSUM dispersion charts

Quality and Reliability Engineering International, 2021
The conventional CUSUM chart is usually designed for a known shift size against which the protection is required. In practice, the shift sizes are rarely known, but they may vary within a given interval.

A nonparametric CUSUM chart for monitoring multivariate serially correlated processes

Journal of QualityTechnology, 2020
In applications, most processes for quality control and management are multivariate. Thus, multivariate statistical process control (MSPC) is an important research problem and has been discussed extensively in the literature. Early MSPC research is based

A non-parametric CUSUM control chart for process distribution change detection and change type diagnosis

International Journal of Production Research, 2020
Non-parametric control charts have been good alternatives to parametric control charts when little information is known about the type of process distribution or the value of parameters.

A Comprehensive Review and Comparison of CUSUM and Change-Point-Analysis Methods to Detect Test Speededness

Multivariate Behavioral Research, 2020
Cumulative sum (CUSUM) and change-point analysis (CPA) are two well-established statistical process control methods to detect changes in a sequence. Both have been used in psychometric research to detect aberrant responses in a response sequence, e.g ...

Distribution-free mixed GWMA-CUSUM and CUSUM-GWMA Mann–Whitney charts to monitor unknown shifts in the process location

Communications in statistics. Simulation and computation, 2020
The Mann–Whitney (MW) test is one of the most important nonparametric tests used in the comparison of the location parameters of two populations. Unlike the t-test, the MW test can be used when the assumption of normality fails to hold.

A distribution‐free CUSUM chart for joint monitoring of location and scale based on the combination of Wilcoxon and Mood statistics

Quality and Reliability Engineering International, 2020
We propose a distribution‐free cumulative sum (CUSUM) chart for joint monitoring of location and scale based on a Lepage‐type statistic that combines the Wilcoxon rank sum and the Mood statistics.
