Efficient control charts for monitoring process CV using auxiliary information
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)Coefficient of variation (CV) control charts are a suitable choice for the monitoring of variation in cases when the process standard deviation is proportional to the process mean. This study is aimed at enhancing the ... -
Enhanced adaptive multivariate EWMA and CUSUM charts for process mean
( Taylor and Francis Ltd. , 2021 , Article)The multivariate charts are mostly used to simultaneously monitor several quality characteristics in manufacturing processes. In this study, we enhance the sensitivities of the recently proposed adaptive multivariate EWMA ... -
Novel Mixed EWMA Dual-Crosier CUSUM Mean Charts without and with Auxiliary Information
( Hindawi Limited , 2022 , Article)The classical cumulative SUM (CUSUM) chart is commonly used to monitor a particular size of the mean shift. In many real processes, it is assumed that the shift level varies within a range, and the exact level of the shift ... -
On Phase-I monitoring of process location parameter with auxiliary information-based median control charts
( MDPI AG , 2020 , Article)A control chart is often used to monitor the industrial or services processes to improve the quality of the products. Mostly, the monitoring of location parameters, both in Phase I and Phase II, is done using a mean control ...
