Question

A firm is faced with the attractive situation in which it can obtain immediate delivery of an item
it stocks for retail sale. The firm has therefore not bothered to order the item in any systematic
way. Recently, however, profits have been squeezed due to increasing competitive pressures, and
the firm has retained a management consultant to study its inventory management. The consultant
has determined that the various costs associated with making an order for the item stocked
are approximately $30 per order. She has also determined that the costs of carrying the item in
inventory amount to approximately $20 per unit per year (primarily direct storage costs and foregone
profit on investment in inventory). Demand for the item is reasonably constant over time and the forecast is for 19,200 units per year. When an order is placed for the item, the entire order
is immediately delivered to the firm by the supplier. The firm operates 6 days a week plus a
few Sundays, or approximately 320 days per year. Determine The number of operating days between orders, based on the optimal number of orders
