Directionally sensitive homogeneously weighted moving average control charts
(
Wiley
, 2021 , Article)
One-sided control charts for monitoring changes in the mean level are proposed in this paper. The proposed charts are given in the form of a homogeneously weighted moving average technique that provides efficient monitoring ...
Exponentially weighted moving average control charts for monitoring coefficient of variation under ranked set-sampling schemes
(
Taylor and Francis
, 2021 , Article)
Several coefficients of variation (CV) control charts under simple random schemes (SRS) have been proposed to monitor process relative variability. However, little attention has been given to investigating the performance ...
Multivariate control charts for monitoring process mean vector of individual observations under regularized covariance estimation
(2021 , Article)
Multivariate control charts are generally used in industries for monitoring and diagnosing processes characterized by several process variables. The applications of charts assume that the in-control process parameters are ...
Auxiliary-information-based efficient variability control charts for Phase I of SPC
(
John Wiley and Sons Ltd
, 2020 , Article)
The inclusion of correlated auxiliary variables into the monitoring scheme of quality characteristic of interest has gained notable attention in recent statistical process control (SPC) literature. Several authors have ...
One-Sided and Two One-Sided Multivariate Homogeneously Weighted Moving Charts for Monitoring Process Mean
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Multivariate memory-type control charts that use information from both the current and previous process observations have been proposed. They are designed to detect shifts in both upper and downward directions with equal ...
