Efficient homogeneously weighted dispersion control charts with an application to distillation process
Abbasi, Saddam Akber; Nassar, Sara Hussam; Aldosari, Mashael Mohammed; Adeoti, Olatunde A. ( 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 ... -
Multivariate control charts for monitoring process mean vector of individual observations under regularized covariance estimation
Omolofe, Olusola T.; Adegoke, Nurudeen A.; Adeoti, Olatunde A.; Fasoranbaku, Olusoga A.; Abbasi, Saddam Akber (2021 , Article)Multivariate control charts are generally used in industries for monitoring and diagnosing processes characterized by several process variables. The applications of charts assume that the in-control process parameters are ...
