MAX-EWMA CHART FOR AUTOCORRELATED PROCESSES (MEWMAP CHART)

The South African Journal of Industrial Engineering, 2012
<p>ENGLISH ABSTRACT: This paper proposes an exponentially weighted moving average (EWMA) control chart that is capable of detecting changes in both process mean and standard deviation for autocorrelated data (referred to as the Maximum Exponentially Weighted Moving Average Chart for Autocorrelated Process, or MEWMAP chart). This chart is based on

Design of EWMA-type control chart

IOP Conference Series: Materials Science and Engineering, 2021
Abstract A control chart is typically examined based on the overall performance. This is crucial, as it will influence the final decision on the selection of a control chart. For this reason, the application of average run length (ARL) has been identified as the standard performance metric.

Prediction of Depression Relapse Using Machine Learning With Administrative Data: Balancing Complexity and Simplicity

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Depression is a mental disorder with a high lifetime prevalence and one of the leading causes of disability worldwide. As many patients experience another depressive episode after being treated, predictive monitoring for the risk of relapse is essential for healthcare professionals to be able to follow up on patients and intervene early ...

Design of a Control Chart Using Extended EWMA Statistic

Technologies, 2018
In the present paper, we propose a control chart based on extended exponentially weighted moving average (EEWMA) statistic to detect a quick shift in the mean. The mean and variance expression of the proposed EEWMA statistic are derived.

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.

ARL‐Unbiased Exponential Control Charts With Estimated Parameters: Statistical Design and Implementation

Quality and Reliability Engineering International, Volume 41, Issue 6, Page 2587-2600, October 2025.
ABSTRACT The bias of a control chart is an important factor in practical applications. Average run length (ARL)‐biased control charts have their out‐of‐control (OOC) ARL (ARLOOC) greater than the in‐control (IC) ARL (ARLin) for some values of the monitored parameter.

The Pre‐Classified PBRTQC Model Can Reduce the False Positive Rate of K+

iLABMED, Volume 3, Issue 3, Page 283-291, September 2025.
Establishing patient‐based real‐time quality control models through pre‐classification of dialysis patients can significantly lower the false positive rate of K+, enhancing the accuracy of real‐time monitoring for laboratory testing systems. ABSTRACT Background Patient‐based real‐time quality control (PBRTQC) has garnered increasing attention, yet ...
