Predictive condition monitoring of industrial systems for improved maintenance and operation [PDF]

open access: yes, 2014
Maintenance strategies based on condition monitoring of the different machines and devices in an industrial process can minimize downtime, increase the safety of plant operations and help in the process of decision-taking for control and maintenance ...

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 ...

A Review and Perspective on Neutrosophic Statistical Process Monitoring Methods

open access: yesIEEE Access, 2022
We review the literature on statistical process monitoring methods based on neutrosophic principles. We question some of the underlying assumptions and raise important questions about these and other neutrosophic statistical methods that need to be ...

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 ...

Nonstationary Process Monitoring Based on Cointegration Theory and Multiple Order Moments

open access: yes, 2022
In industrial processes, process data often exhibit complex characteristics, such as nonstationarity and nonlinearity, which brings challenges to process monitoring.

Vehicle Driver Monitoring through the Statistical Process Control

open access: yesSensors, 2019
This paper proposes the use of the Statistical Process Control (SPC), more specifically, the Exponentially Weighted Moving Average method, for the monitoring of drivers using approaches based on the vehicle and the driver’s behavior. Based on the SPC, we

State-space independent component analysis for nonlinear dynamic process monitoring [PDF]

open access: yes, 2010
The cost effective benefits of process monitoring will never be over emphasised. Amongst monitoring techniques, the Independent Component Analysis (ICA) is an efficient tool to reveal hidden factors from process measurements, which follow non-Gaussian
