CS‐EWMA Chart for Monitoring Process Dispersion
Quality and Reliability Engineering International, 2012Control charts are the most extensively used technique to detect the presence of special cause variations in processes. They can be classified into memory and memoryless control charts. Cumulative sum and exponentially weighted moving average control charts are memory‐type control charts as their control structures are developed in such a way that the ...

The efficiency of the EWMA capability chart
2007 IEEE International Conference on Industrial Engineering and Engineering Management, 2007In order to monitor unstable but capable processes Castagliola & Vannman have recently suggested a procedure based on an EWMA approach, called EWMA capability chart, for monitoring Vannman's Cp(u,v)-family of capability indices and showed how their proposed approach efficiently monitors capable processes by detecting a decrease or increase of the ...

Multivariate EWMA Charts with Variable Sampling Intervals
Economic Quality Control, 2009Summary: The standard multivariate control chart usually employs fixed sample sizes at fixed sampling intervals (FSI) to monitor a process. In this study, a multivariate exponentially weighted moving average (MEWMA) chart with variable sampling intervals (VSI) is investigated.

The Misguided Adaptive EWMA Chart
Quality and Reliability Engineering InternationalABSTRACTA new adaptive EWMA (AE) chart has been recently introduced for monitoring the mean of a normally distributed process. Using this variant of the AE chart, numerous papers have been written in statistical process monitoring literature. In this paper, the performance of the AE chart is reevaluated using the conditional expected delay metric.
