X Camera stocks two items in its warehouse which it purchases from an outside supplier. Demand for the two items are independent; the inventory carrying percentage is 20% and for each item, the demand during lead time is a normal random variable with mean = 100 and standard deviation = 20. Since customers are willing to wait for the camera when he is out of stock, the shortage penalty is low. The relevant data for each item are the same and shown below.
