Let us suppose the demand at a firm is 200 units per month. The firm orders 80 units each time. How many times does the firm place an order per year? What is the average inventory level at this firm?
Let us suppose the demand at a firm is 200 units per month.
Then annual demand = monthly demand * 12 = 200 units *12 = 2,400 units
Order quantity per order = 80 units
Number of order per year = Annual demand / Order quantity per order
= D/ Q = 2,400 units / 80 units =30 orders per year
The average inventory level = Order quantity per order / 2
= 80 units / 2 = 40 units
Therefore the firm place an order 30 times per year and the average inventory level at this firm is 40 units.
