    • Efficient cv control charts based on ranked set sampling 

      Abbasi, Saddam Akber; Abbas, Tahir; Adegoke, Nurudeen Adedayo ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)
      Monitoring process variability is essential for establishing efficient process-control schemes. In practice, when the mean levels of a parameter are constant, and the process variance (or standard deviation) is independent ...

    • Exponentially weighted moving average control charts for monitoring coefficient of variation under ranked set-sampling schemes 

      Alabi, Oluwapelumi; Adegoke, Nurudeen A.; Adebola, Femi Barnabas; Oseni, Bamidele Mustapha; Abbasi, Saddam Akber ( Taylor and Francis , 2021 , Article)
      Several coefficients of variation (CV) control charts under simple random schemes (SRS) have been proposed to monitor process relative variability. However, little attention has been given to investigating the performance ...
