Within the context of flexible parametric families of distributions, much work has been
dedicated in recent years to the theme of skew-symmetric distributions, or symmetry …

In this study, a Shewhart type control chart, namely VR chart, has been proposed to monitor
a process that follows Rayleigh distribution. The proposed VR chart is implemented to …

Control chart is a statistical process control tool to routinely monitor the quality of a process.
In the past decade, using auxiliary information to enhance the ability of control chart to detect …

In this paper, the inference on location parameter for the skew-normal population is
considered when the scale parameter and skewness parameter are unknown. Firstly, the …

The normality assumption is a significant part of the development of control charts. This
underlying assumption of normality most likely does not hold true in real scenarios. One of …

In the real world, we often observe that the underlying distribution of some Gaussian
processes tends to become skewed, when some undesirable assignable cause takes place …

In recent years, researchers introduced several distribution-free schemes for simultaneously
monitoring the location and scale parameters of distribution in the literature related to …

In this study, two new integrated control charts, named T 2-MAE chart and MS-MAE chart,
are introduced for monitoring the quality of a process when the mathematical form of …

Different normality-based optimization strategy (NBOS) methods have been developed and
used to perform quality improvement in the past few decays. Improving the quality of a …

Several structures of mean control chart based on ranked set schemes are available in
literature. These structures involve assumptions, that is, process distribution is known and …
