Hi,
I'm seeking some help with the above topic.
I'm researching the possibility of using Cpk for the purpose of determining sample size/frequencies.
I'm of the opinion that if a process has proven to be stable and common sources of variation eliminated, and it has held this state of control over a period of time, say 2 or 3 months then couldn't one say it's time to review the current sampling scheme.
If this can be done how is it done?
Is it possible to convert the Cpk value into something that relates to a sampling plan AQL?
Can someone please point me to some papers, journals or text that explains how this can be acheived?
Thanks in advanced,
Nick Viney
