Efficient homogeneously weighted dispersion control charts with an application to distillation process
(
Wiley
, 2021 , Article)
Monitoring disturbances in process dispersion using control chart is mostly based on the assumption that the quality characteristic follows normal distribution, which is not the case in many real-life situations. This paper ...
Efficient bivariate EWMA charts for monitoring process dispersion
(
John Wiley and Sons Ltd
, 2020 , Article)
To ensure high quality standards of a process, the application of control charts to monitor process performance has become a regular routine. Multivariate charts are a preferred choice in the presence of more than one ...
A non-parametric double homogeneously weighted moving average control chart under sign statistic
(
John Wiley and Sons Ltd
, 2021 , Article)
In practical situations, the underlying process distribution sometimes deviates from normality and their distribution is partially or completely unknown. In that instance, rather than staying with/depending on the conventional ...
