I NEED IT TODAY,
1. B&H needs to decide how to manage its inventory of cameras. The demand for cameras at B&H is 200 cameras per week. Each time that B&H places an order for a new shipment of cameras, it must pay $80 in fixed processing fees. A camera costs B&H $60 to purchase. The cost for B&H to hold a camera in its store for one week is $4. Assume that the lead time for the delivery of a camera is 0 weeks.
a. Suppose that B&H places orders for cameras in quantities of 50 cameras at a time and places a new order for cameras each time that it runs out. Draw a graph showing the number of cameras that B&H has on-hand in inventory at each point in time up until the time when it places its fourth order. Label the points in time at which B&H places a new order. Assume that B&H places its first order for 50 cameras on day 0.
b. Suppose again that B&H places orders for 50 cameras at a time. What will be B&H’s average holding costs per week? What will be B&H’s average fixed ordering costs per week?
c. What is the optimal number of cameras for B&H to order each time that it places an order? Assuming that B&H orders according to its optimal ordering quantity (EOQ), what will be B&H’s average fixed ordering costs over the course of a week? What will be B&H’s average holding costs over the course of a week?
d. Suppose now that the lead time for the delivery of a shipment of cameras increases to 0.2 weeks. Assuming that B&H orders according to its optimal order quantity from part c above, what should be B&H’s reorder point for a shipment of cameras?
e. Suppose that the lead time for the delivery of cameras is still 0.2 weeks. However, rather
than placing an order when B&H’s inventory of cameras reaches its reorder point calculated in part d above, B&H decides to place a new order for cameras whenever it has 60 cameras in inventory. How much additional holding costs (over the EOQ holding costs) will B&H incur as a result of this ordering policy? (Suppose that B&H orders according to the EOQ level each time that it places an order.)
f. [Extra Credit] Suppose now that the lead time for the delivery of a shipment of cameras increases to 0.5 weeks. Assuming that B&H orders according to its optimal order quantity from part c above, what should be B&H’s reorder point for a shipment of cameras? Explain carefully your answer.
3. A pastry shop is considering how much hot chocolate to prepare each morning. Hot chocolate costs $0.10 per oz to make and sells for $0.40 per oz. Customers can buy hot chocolate in any number of ounces that they wish. Any hot chocolate not sold by the end of the day is discarded. The daily demand for hot chocolate is
