Need advise on the ARL of Cusum EWMA chart
July 16, 2004 at 7:07 am #36178
When I construct the Cusum or EWMA chart, the ARL value does not seem to be needed or maybe I have miss out anything?
So my question is on the ARL value: What is it for? How is it applied/ used?
Any clear advise out there to help me out.
Many thanks.0July 16, 2004 at 11:49 am #103564

You cannot “dial-up” the ARL characteristics. They are a function of lambda, stdev multiplier, and sample size (EWMA) or h, k, sample size (CUSUM). There are also some start-up options for Fast Initial Response.
Search through Journal of Quality Technology and Technometrics for additional information.
