A firm requires 90,000 units (D) over a 120-day production period and is placing 2-orders of equal quantity (O). Inventory is used at a constant daily rate. Ordering and Holding Costs are accounted for at end of the production period. Ordering Costs (OC) are $5,000/order and Holding Costs (HC) are $4.00/unit based on average inventory. The price per unit of inventory is $50 (C"). The firm pays for the inventory 5-days after delivery. The firm's cost of capital is 10% (1). For the inventory system, the SECOND order is delivered at f= and payment for that order is made at f= Total Cost Ordering Costs + Holding Costs + Item Cost Total Cost OCx (D/Q)] + [HC (0/2)] + (C x D) Order Number 1 2 - Delivered At t= ORDERING COSTS HOLDING COSTS 5, 120 60, 65 120, 125 5, 10 0 Order Quantity 45,000 Cost $10,000 Payment Due At t= Ⓒ 5 150 PVF 0.998632 0.960526 PV $9,605

A manufacturer buys cardboard boxes from a supplier. The annual demand is 40,000 boxes and is uniformly distributed. The boxes cost $5 each. The estimated order cost is $10, and the carrying cost rate is 20% per year. What is the EOQ and what is the annual order and carrying cost? How many times a year are orders placed, and what is the average time, in weeks, between orders? Using the answer from (b), if you round the average time between orders to the nearest week, what should the order quantity be? Would you recommend using this order quantity and time interval? Suppose that the actual demand turns out to be 80,000 boxes instead of 40,000 boxes.If you had used the EOQ from the (a), what would be the annual order and carrying cost be?
