Suppose that a business knows what the annual sales of an item will be and that it seeks to arrange a delivery schedule with its supplier in such a way that an equal number of items will be delivered at regular intervals throughout the year. Associated with each delivery there is a delivery cost, which is assumed to be independent of the size of the delivery—think of it as an administrative or fixed shipping cost associated with the act of making a delivery. There is also a cost to maintain inventory, which is determined by the unit carrying cost—the cost of keeping one item in inventory for one year.
