Location charts based on ranked set sampling for normal and non-normal processes
(
John Wiley and Sons Ltd
, 2019 , Article)
Control charts, based on ranked set sampling schemes, had been proposed recently for efficient monitoring of process location. All the proposals in the literature are based on the ideal assumption of normally distributed ...
Optimization design of the CUSUM and EWMA charts for autocorrelated processes
(
John Wiley and Sons Ltd
, 2017 , Article)
The traditional control charts produce frequent false alarm signals in the presence of autocorrelation. The implementation of the modified chart scheme is a way of handling the problem of autocorrelation in control charts. ...
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 ...
New efficient exponentially weighted moving average variability charts based on auxiliary information
(
John Wiley and Sons Ltd
, 2020 , Article)
Control chart is a well-known tool for monitoring the performance of an ongoing process. The variability of a process is an important parameter that may deteriorate the process performance if it is not taken care on time. ...
