Dynamic Safety Stock calculation in AIP
Hi,
We would like to request for information on the specifics of the calculation of Dynamic Safety Stock in AIP.
The calculation guide states:
A standard lookup function using a normal distribution table is then used to determine a factor which is multiplied by the standard deviation for the review time. The acceptable unit loss (AUL) over the review time is used to find the Z-factor needed for the Statistical Safety Stock Calculation. The result of the lookup is multiplied by the lead time deviation to determine the statistical safety stock.
Would anybody know if there is a corresponding Excel function for the "lookup" that AIP is performing as we would like to validate the calculation/results using Excel.
