Hello tutor
I would like like to know how to calculate the yield variance if there are multiple product
I commonly use a formula
SQSP
AQ(SM)SP – these two for finding yield variancesAQ(SM)SP — these two for mix
AQSPhowever, there is another formula
actual yield X
st yield at act output X(X) multiply with with st rate
I am confused with this, how to calculate the rate if there are two products, and question gets much harder especially when they says there is a wastage of 5% for example
Please help me tutor I need to understand this
Have you not watched my free lectures on this, because I explain the ‘rules’ and the reasoning in my lectures?
You cannot simply learn formula to pass Paper PM. If mix and yield variances are asked then in Section C there will always be written parts to check that you really understand what is happening.
Mix and yield variances occur when there are multiple materials used – not when there are multiple products!
well I know we have to interpret the answers
just wanted to know how they calculate the yield variances ?
