Average run length when monitoring capability indices using EWMA

Quality and Reliability Engineering International, 2008
AbstractIn order to monitor unstable but capable processes Castagliola and Vännman have recently suggested a procedure based on an EWMA approach, called EWMA capability chart, for monitoring Vännman's Cp(u,v)‐family of capability indices and showed how their proposed approach efficiently monitors capable processes by detecting a decrease or increase in

Average Run Lengths of Geometric Moving Average Charts by Numerical Methods

Technometrics, 1978
A numerical procedure is presented for the tabulation of average run lengths (ARL's) of geometric moving average charts. Both one-and two-sided ARL's are given for various settings of the control limits, smoothing constant and shift in the nominal level of the process mean. Where comparison is possible.

A Note on Average Run Lengths of Moving Average Control Charts

Economic Quality Control, 2004
Using a counter example, we show that the formula for computing the Average Run Lengths (ARL) of a moving average control chart (MA) in Wetherill and Brown (1991) is incorrect. However, we conjecture that the formula may provide an upper bound for the ARL of a moving average control chart.

Computing Average Run Lengths for the MaxEWMA Chart

Communications in Statistics - Simulation and Computation, 2004
The MaxEWMA chart has recently been introduced as an alternative to control charting procedures that are designed to jointly detect changes in the mean and standard deviation of a normally distributed process. Here, a method for computing both in-control and out-of-control average run lengths for purposes of effectively designing this chart is offered.
