Now, given that the mean , after calculations, we know
Now, given that the mean , after calculations, we know
What is r?
What is the amount of safety stock?
Solution
To get safety stock, we need r and mean (), then get the diff:
  • Because the mean or expected demand during the lead time is 154 units, the units serve as a safety stock,
  • Safety stock absorbs higher-than-usual demand during the lead time.
  • Roughly 95% of the time, the 195 units will be able to satisfy demand during the lead time. T
