Explanation:
Data provided in the question
Weekly demand for a product = 250 units
Standard deviation = 60 units
Lead time = 3 weeks
Service level = 98%
And, the service factor from the normal distribution is 2.05
Now the
Safety stock = Service factor Γ standard deviation Γ βlead time
= 2.05 Γ 60 Γ 1.73
= 212.79
Now the reorder point is
= Weekly demand Γ lead time + safety stock
= 250 units Γ 3 weeks + 212.79
= 962.79
