Sequential control chart methodology [PDF]

open access: yes
A modification of the V mask sequential control chart is proposed. In this modified scheme, a parabolic section is included in the mask to provide better performance when the process undergoes a large change in the mean from goal conditions.

Data De-Noise for Multivariate T2 and S-Charts Using Multivariate Wavelets

open access: yesZanco Journal of Humanity Sciences
In this research, proposed multivariate charts were created corresponding to T2 and S-charts that are robust to noise data by using multivariate wavelet shrinkage, that dealt with the contamination problem before constructing Shewhart charts, through ...

A new procedure for monitoring the range and standard deviation of a quality characteristic [PDF]

open access: yes
The Shewhart and the Bonferroni-adjustment R and S chart are usually applied to monitor the range and the standard deviation of a quality characteristic. These charts are used to recognize the process variability of a quality characteristic.

Negative Binomial charts for monitoring high-quality processes [PDF]

open access: yes, 2008
Good control charts for high quality processes are often based on the number of successes between failures. Geometric charts are simplest in this respect, but slow in recognizing moderately increased failure rates p.

Multivariate control charts based on Bayesian state space models

open access: yes, 2006
This paper develops a new multivariate control charting method for vector autocorrelated and serially correlated processes. The main idea is to propose a Bayesian multivariate local level model, which is a generalization of the Shewhart-Deming model for ...
