Comments on “On Scale Parameter Monitoring of the Rayleigh Distributed Data Using a New Design”

open access: yesIEEE Access, 2022
We provide comments on a research paper proposing a control chart to monitor the scale parameter of a Rayleigh distribution. Our primary focus is on improving its average run length profile.

Feature-based statistical process monitoring for pressure swing adsorption processes

open access: yesFrontiers in Chemical Engineering, 2022
Pressure swing adsorption (PSA) is a widely used technology to separate a gas product from impurities in a variety of fields. Due to the complexity of PSA operations, process and instrument faults can occur at different parts and/or steps of the process.

Quality-Related Process Monitoring Based on Improved Kernel Principal Component Regression

open access: yesIEEE Access, 2021
To date, quality-related multivariate statistical methods are extensively used in process monitoring and have achieved admirable effects. However, most of them contain recursive processes, which result in higher time complexity and are not suitable for ...

Phase I Monitoring of Multivariate Ordinal Based Processes: The MR and LRT Approaches (A Real Case Study in Drug Dissolution Process) [PDF]

open access: yesInternational Journal of Industrial Engineering and Production Research, 2022
In some statistical processes monitoring (SPM) applications, relationship between two or more ordinal factors is shown by an ordinal contingency table (OCT) and it is described by the ordinal Log-linear model (OLLM). Newton-Raphson algorithm methods have

Monitoring the Zero-Inflated Time Series Model of Counts with Random Coefficient

open access: yesEntropy, 2021
In this research, we consider monitoring mean and correlation changes from zero-inflated autocorrelated count data based on the integer-valued time series model with random survival rate.

A Combined Runs Rules Scheme for Monitoring General Inflated Poisson Processes

open access: yesMathematics, 2023
In this work, a control chart with multiple runs rules is proposed and studied in the case of monitoring inflated processes. Usually, Shewhart-type control charts for attributes do not have a lower control limit, especially when the in-control process ...
