Demand for a product is 3200 TL units per quarter. Each order has a fixed cost of 2500 TL. Annual holding cost per product is 80 TL.
Calculate: a) number of products that the company should order
b) average inventory
c) number of orders per year
d) expected time between orders
e) total relevant cost
Quarterly Demand = 3200
Annual Demand = D = 3200 * 4 = 12800 units
Order cost = S = 2500
Annual Holding cost = H = 80
a) Number of products that the company should order = EOQ = = = 894.43 units
b) Average inventory = EOQ / 2 = 894.43 / 2 = 447.21 units
c) Number of orders per year = D / EOQ = 12800 / 894.43 = 14.31 orders
d) Expected time between orders = 12 months / No. of orders per year = 12 / 14.31 = 0.84 months
e) Total relevant cost = Ordering Cost + Annual Holding cost = No. of orders * S + Average Inventory * H = 14.31 * 2500 + 447.21 * 80 = 35,775 + 35,776.8 = $71,551.8
