    • Efficient control charts for monitoring process CV using auxiliary information 

      Abbasi, Saddam Akbar ( 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 ...

    • Efficient monitoring of coefficient of variation with an application to chemical reactor process 

      Mahmood, Tahir; Abbasi, Saddam Akber ( John Wiley and Sons Ltd , 2021 , Article)
      Control chart is a useful tool to monitor the performance of the industrial or production processes. Control charts are mostly adopted to detect unfavorable variations in process location (mean) and dispersion (standard ...

    • Monitoring Coefficient of Variation Using Progressive Mean Technique 

      Abbasi S.A.; Mohamed M.A.; Ahmed M.A.; Lajara R.J.; Hadi H.F. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)
      Control charts are mostly used for the monitoring of process mean and dispersion. In cases, when the process standard deviation is proportional to the mean, it is recommended to use control charts based on coefficient of ...

    • On the performance of coefficient of variation control charts in Phase I 

      Dawod A.B.A.; Abbasi S.A.; Al-Momani M. ( John Wiley and Sons Ltd , 2018 , Article)
      Control charts are mainly carried out in 2 interconnected phases: Phase I (retrospective phase) and Phase II (monitoring phase). Phase I uses a stable historical sample to establish control limits that will be used later ...
