Weibull‐Neural Network Framework for Wind Turbine Lifetime Monitoring and Disturbance Identification

Wind Energy, Volume 29, Issue 4, April 2026.
ABSTRACT Wind turbines are vital for sustainable energy, yet their reliability under diverse operational and environmental conditions remains a challenge, often leading to costly failures. This study presents a novel Weibull‐Neural Network Framework to enhance wind turbine lifetime monitoring by estimating reliability (R(t)) and mean residual life (MRL)

Shewhart methodology for modelling financial series : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Statistics at Massey University, Palmerston North, New Zealand [PDF]

, 2017
Quality management techniques are widely used in industrial applications for monitoring observable process variation. Among them, the scientific notion of Shewhart principles is vital for understating variations in any type of process or service.

Enhancing Food Safety in the Cold Chain Through Internet of Things and Artificial Intelligence

Journal of Food Science, Volume 91, Issue 2, February 2026.
ABSTRACT Effective cold chain management is crucial for ensuring food safety, but traditional monitoring approaches remain reactive and fragmented. Industry 4.0 technologies, such as the Internet of Things (IoT) and artificial intelligence (AI), offer transformative potential for real‐time tracking, automation, and predictive analytics.

Acceptance Control Charts

Zeszyty Naukowe Uniwersytetu Ekonomicznego w Krakowie, 2016
The main goal of this article was to review and analyse basic control charts, which can be used to accept or disqualify an analysed production process. There are two kinds of acceptance control charts: Shewhart and cumulative sum (CUSUM charts). Both can

Control charts using minima instead of averages [PDF]

, 2006
Traditional control charts are commonly based on the averages of the inspected groups of observations. It turns out to be quite worthwhile to consider alternative approaches.

Evaluating the Effectiveness of Control Charting Schemes in Detecting Malicious Attacks Targeting Manufacturing Systems

Quality and Reliability Engineering International, Volume 41, Issue 7, Page 2952-2973, November 2025.
ABSTRACT The increasing risk and impact of cyber‐physical attacks on the manufacturing industry are driven by vulnerabilities in industrial control systems and digital manufacturing technologies. These attacks can be strategically engineered to modify product dimensions while evading detection by current quality control (QC) tools.

A Robust L‐Comoments Covariance Matrix‐Based Hotelling's T2${T^{2}}$ Control Chart for Monitoring High‐Dimensional Non‐Normal Multivariate Data in the Presence of Outliers

Quality and Reliability Engineering International, Volume 41, Issue 7, Page 3308-3317, November 2025.
ABSTRACT This article introduces a new robust multivariate Hotelling T‐square (TS) control chart that incorporates an L‐Comoments covariance matrix into a multivariate statistical process control (MSPC) charting scheme to enhance its robustness and detection ability.

A comparative analysis of mean charts assuming Weibull and generalized exponential distributions

Heliyon
This study discusses Shewhart control charts to monitor the mean of non-normally distributed data using extensive Monte Carlo simulations. In particular, Weibull, exponential, and generalized exponential distributions are used to conduct a systematic ...

Prediction Intervals for Overdispersed Binomial Endpoints and Their Application to Toxicological Historical Control Data

Pharmaceutical Statistics, Volume 24, Issue 5, September/October 2025.
ABSTRACT For toxicology studies, the validation of the concurrent control group by historical control data (HCD) has become requirements. This validation is usually done by historical control limits (HCL), which should cover the observations of the concurrent control with a predefined level of confidence.
