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 linear profile schemes for monitoring bivariate correlated processes with applications in the pharmaceutical industry
Dawod, Abdaljbbar B.A.; Adegoke, Nurudeen A.; Abbasi, Saddam Akbar ( Elsevier , 2020 , Article)The complexity of chemical processes warrants that collection of information about the processes will continue as they proceed through the various stages of industrialization. Process monitoring has emerged as an essential ... -
Improved simple linear profiling method with application to chemical gas sensors
Abbasi, Saddam Akbar; Abbas, Tahir; Adegoke, Nurudeen Adedayo ( John Wiley and Sons Ltd , 2021 , Article)In industrial applications, a functional relationship between the quality characteristics of interest is well represented by profile functions. These are often characterized by linear or nonlinear relationships that depend ... -
Novel Mixed EWMA Dual-Crosier CUSUM Mean Charts without and with Auxiliary Information
Arslan, Muhammad; Ashraf, Muhammad Azeem; Anwar, Syed Masroor; Rasheed, Zahid; Hu, Xuelong; Abbasi, Saddam Akbar... more authors ... less authors ( 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 ... -
A Novel Simulation-Based Adaptive MEWMA Approach for Monitoring Linear and Logistic Profiles
Yeganeh, Ali; Abbasi, Saddam Akbar; Shongwe, Sandile Charles ( IEEE , 2021 , Article)As a common approach in the development of control charts in Statistical Process Control (SPC), an industrial process is monitored with one or more quality characteristics using their corresponding distributions. Note ...
