specification maintenace

Post by epvn » Sun Sep 25, 2011 5:46 pm

Hi experts,

We have an unique requiremnt,
MIC 1 = 1.2 -1.7 (ist grade) & less than 1.2 & 1.8 - 1.9 (2nd grade) but 2.0 and above 3rd grade

if i am using multiple specification, but i am not able to maintain the specification - less than1.2 and 1.8-1.9 will be acceptable & if it is1.2 -1.7 and more than1.9 will rejected
how to map it...is there any way

for business this must & currently they have legacy system which is maintained

definetly expert came across this kind of requirement & please throw some lights

thanks
Srinivasan

I'd probably use a combination of calculated characteristics.

MIC 1 = 1.2 - 3.0 (record the actual value against this)
MIC 2 = 1.2 - 1.9 (calculated MIC - value = MIC 1)
MIC 3 = 1.2 - 1.7 (calculated MIC - value = MIC 1)

If all three mics pass, auto UD can done to Grade 1.
If MIC 1 & 2 pass, but MIC 3 is rejected, then Grade 2
If MIC 1 passes, but MIC 2 & 3 fail, then Grade 3

If all three MIC's fail, reject.
