Brooke Army Medical Center dispenses 250,000 bottles of brand name pharmaceutical annually. The optimal safety stock (which is on hand initially) is 1,000 bottles. Each bottle costs the center $10, inventory carrying costs are 30 percent, and the cost of placing an order with its supplier is $175. Orders can be placed only in multiples of 100 units.
