Homework Answers
Mean lead time demand for BX-5 = 65
The standard deviation of demand = 8
Desired service level = 90%
Z-value for achieving 90% service level = 1.28
Ans a)
Safety stock = Z * Standard deviation of demand
= 1.28 * 8
= 10.24 or 10 units
Ans b)
Appropriate re-order point = Mean lead time demand + Safety stock
= 65 + 10
= 75 units
