#2
If desired serice level percentage is 99%, then to calculate required reorder stock use following steps-
1. Use NORMSINV excel function to get the multiplier factor to standard deviation
= NORMSINV(0.99)
=2.326
2. Std Deviation * Multiplier = 32 * 2.326 ~ 74
3. Reorder value to achieve 99% service level = 200 + 74 = 274
But reorderd value is 252
So it will not achive 99% service level
Answer False
#4
Coefficient of variation = Std Deviation / Mean
= 25 / 100
= 0.25
Answer False
