  6. One unit of A is made of three units of B, one unit of C, and two units of D. B is composed of two units of E and one unit of D. C is made of one unit of B and two units of E. E is made of one unit of F. Items B, C, E, and F have one-week lead times; A and D have lead times of two weeks. Assume that lot-for-lot (L4L) lot sizing is used for Items A, B, and F; lots of sizes 50, 50, and 200 are used for Items C, D, and E, respectively. Items C, E, and F have onhand (beginning) inventories of 10, 50, and 150, respectively; all other items have zero beginning inventory. We are scheduled to receive 10 units of A in Week 2, 50 units of E in Week 1, and also 50 units of F in Week 1. There are no other scheduled receipts. If 30 units of A are required in Week 8, use the low-level-coded bill-of-materials to find the necessary planned order releases for all components.

Every two weeks (14 days) inventory is counted and a new order is placed. It takes 10 days for the sheets to be delivered. The standard deviation of demand for the sheets is five per day. There are currently 150 sheets on hand. How many sheets should you order?

  10. Charlie’s Pizza orders all of its pepperoni, olives, anchovies, and mozzarella cheese to be shipped directly from Italy. An American distributor stops by every four weeks to take orders. Because the orders are shipped directly from Italy, they take three weeks to arrive. Charlie’s Pizza uses an average of 150 pounds of pepperoni each week, with a standard deviation of 30 pounds. Charlie’s prides itself on offering only the best quality ingredients and a high level of service, so it wants to ensure a 98 percent probability of not stocking out on pepperoni. Assume that the sales representative just walked in the door and there are currently 500 pounds of pepperoni in the walk-in cooler. How many pounds of pepperoni would you order?
