Linear profile monitoring using EWMA structure under ranked set schemes
(
Springer London
, 2017 , Article)
In many manufacturing processes, study variable is not the only quality characteristic, but there may exist some explanatory variable(s) that are associated with the study variable. This association may be linear or nonlinear ...
Efficient GLM-based control charts for Poisson processes
(
John Wiley & Sons, Ltd
, 2022 , Article)
The control charts are essential instruments that can impart crucial insights to quality controllers for maintaining the productivity of manufacturing processes. The conventional charting designs are based on a single study ...
Online monitoring of climatic parameters: a statistical study about environmental changes in Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Twentieth century has witnessed unprecedented changes in the climate whose profound effects are also observed on ecosystem and human life. The source of these changes are presumed to be increasing concentration of greenhouse ...
Efficient monitoring of coefficient of variation with an application to chemical reactor process
(
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 ...
An Improved Control Chart for Monitoring Linear Profiles and its Application in Thermal Conductivity
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In most of the manufacturing processes, we encounter different quality characteristics of a product and process. These characteristics can be categorized into two kinds; study variables (variable of interest) and the ...
Multivariate Mixed EWMA-CUSUM Control Chart for Monitoring the Process Variance-Covariance Matrix
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
The dispersion control charts monitor the variability of a process that may increase or decrease. An increase in dispersion parameter implies deterioration in the process for an assignable cause, while a decrease in ...
