Anomaly Detection for Compositional Data using VSI MEWMA control chart
Thi Thuy Van Nguyen, Cédric Heuchenne, Kim Phuc Tran
In recent years, the monitoring of compositional data using control charts has been investigated in the Statistical Process Control field. In this study, we will design a Phase II…
The Effect of Autocorrelation on the Shewhart-RZ Control Chart
H. D. Nguyen, A. Ahmadi Nadi, K. P. Tran +3
In many industrial manufacturing processes, the quality of products depends on the relation between two main ingredients or characteristics. Often, this calls for monitoring the ra…
One-sided Shewhart control charts for monitoring the ratio of two normal variables in Short Production Runs
K. D. Tran, Q. U. A Khaliq, A. A. Nadi +2
Monitoring the ratio of two normal random variables plays an important role in several manufacturing environments. For short production runs, however, the control charts assumed in…
Monitoring the Multivariate Coefficient of Variation using Run Rules Type Control Charts
P. H. Tran, A. C. Rakitzis, H. D. Nguyen +3
In practice, there are processes where the in-control mean and standard deviation of a quality characteristic is not stable. In such cases, the coefficient of variation (CV) is a m…
