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 ...
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 ...
