A distributor of large appliances needs to determine the order quantities and reorder points for the various products it carries. The following data refer to a specific refrigerator in its product line. Cost to place an order $100 / order
Holding cost 20 percent of product cost per year
Cost of refrigerator $500 / unit
Annual demand 500 units
Standard deviation of
demand during lead time 10 units
Lead time 7 days
Consider an even daily demand and a 365-day year.
a. What is the economic order quantity?
b. If the distributor wants a 97 percent service probability, what reorder point, R, should be used?
