A Cold Inc. is a frozen-food distributor with 10 warehouses across the country. Ivan Tory, one of the warehouse managers, wants to make sure that the inventory policies used by the warehouse are minimizing inventory while still maintaining quick delivery to ACold's customers. Because the warehouse carries hundreds of different products, Ivan decided to study one. He picked Caruso's Frozen Pizza (CFP). Demand for CFPs averages 400 per day with a standard deviation of 152. Ivan notes that any order for CFPs arrives four days after the order.
