The State of Statistical Process Control as We Proceed into the 21st Century
TL;DR: The State of Statistical Process Control as We Proceed into the 21st Century Journal of the American Statistical Association: Vol 95, No 451, pp 992-998 as discussed by the authors, 2000
Journal ArticleDOI
A CUSUM Chart for Monitoring a Proportion When Inspecting Continuously
TL;DR: A control chart is considered for the problem of monitoring a process when all items from the process are inspected and classified into one of two categories.
Journal Article
Robustness to non-normality of the multivariate EWMA control chart
TL;DR: In this article, the effects of non-normality on the statistical performance of the multivariate exponentially moving average (MEWMA) control chart, and the Hotelling chi-squared chart in particular, are investigated when used in individual observations to monitor the me.
Journal ArticleDOI
Monitoring the Process Mean and Variance Using Individual Observations and Variable Sampling Intervals
TL;DR: In this paper, the authors investigate control charts for monitoring a process to detect changes in the mean and variance of a normal quality variable when an individual observation is taken at each samplacement.
Journal ArticleDOI
Control Charts and the Efficient Allocation of Sampling Resources
TL;DR: The overall conclusion is that it is best to take samples of n = 1 observations and use an EWMA or CUSUM chart combination, which seems to contradict the conventional wisdom about some of the advantages and disadvantages of EWMA and C USUM charts relative to Shewhart charts.
