c=0 Acceptance Sampling Plan similar to the N. Squeglia version

Hi Guys,

Was hoping someone could help me understand the following....

The one we are currently using is very similar to but not the same as the N. Squeglia version.
i.e. for AQL 2.5 Sample size 26-50 is 7, it is 5 in the N. Squelia version. For sample size 51-90 n=11 in my table and 7 in the N. Squeglia version?:eek:

I need to figure out how to reverse these numbers to calculate the associated AQL, LTPD,Alpha and Beta values.

Anyone have any ideas?

Thanks :)

I posted a spreadsheet here a while ago that could help you "reverse engineer" the sampling plans. It allows you find appropriate sampling plans based on sample size, acceptance number, alpha & beta.

Play with the parameters to see how they fit with your particular plans. I don't have more time now, but I can check back later today to say more or answer questions.

Here is a link to the thread with the spreadsheet.
