On improved monitoring of linear profiles under modified successive sampling
(
John Wiley and Sons Ltd
, 2019 , Article)
Control charts are often used for the monitoring of quality characteristics of interest. There may exist some other characteristics that are associated with the main quality characteristic. A model that quantifies the ...
Enhancing the performance of the EWMA control chart for monitoring the process mean using auxiliary information
(
John Wiley and Sons Ltd
, 2019 , Article)
When using control charts to monitor manufacturing processes, the exponentially weighted moving average (EWMA) control chart is useful for detecting persistent shifts in the process parameter. This paper proposes enhancements ...
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. ...
