Statistical Process Monitoring

Convex hulls represent a powerful geometric tool with broad applications in multivariate data analysis and statistical process monitoring. In this work, we introduce two methodologies that leverage convex hull properties for anomaly detection, change tracking in complex systems, and enhancement of the sensitivity of classical process control charts. Experimental results indicate that the...

Statistical Process Monitoring

In this work, we study the behavior of nonparametric Shewhart-type control charts, which employ order statistics and multiple runs-type rules. The proposed class of monitoring schemes include some existing control charts. In addition, new distribution-free monitoring schemes that pertain to the class, are set up and examined extensively. Explicit expressions for determining the variability and...

Statistical Process Monitoring

The focus on every experimental process is observing, studying and understanding phenomena, which are of multivariate nature. The rapid growth of computational power, in combination with the existence of different statistical packages, has facilitated the data collection and led to the development of statistical techniques for monitoring and surveillance. In real world settings, the...
