MOVING AVERAGE AND DOUBLE MOVING AVERAGE CONTROL CHARTS FOR PROCESS VARIABILITY USING AUXILIARY INFORMATION

2023
The memory type control charts based on auxiliary information have been introduced in the literature for improved monitoring of the process parameters for normally distributed process. In this paper, we design moving average and double moving average control charts based on auxiliary information for efficient monitoring the shifts in the process ...

A Double Moving Average Control Chart

Communications in Statistics - Simulation and Computation, 2008
The double exponentially weighted moving average (DEWMA) technique has been investigated in recent years for detecting shifts in the process mean and has been shown to be more efficient than the corresponding exponentially weighted moving average (EWMA) technique.

Double moving average–EWMA control chart for exponentially distributed quality

Communications in Statistics - Simulation and Computation, 2017
A control chart is an ever-popular tool for monitoring the production process. The early detection of a process shift, if any, is the desire of the quality control personnel.

A new nonparametric double exponentially weighted moving average control chart

Quality and Reliability Engineering International, 2019
AbstractThere are many practical situations where the underlying distribution of the quality characteristic either deviates from normality or it is unknown. In such cases, practitioners often make use of the nonparametric control charts. In this paper, a new nonparametric double exponentially weighted moving average control chart on the basis of the ...
