Chapter 11, Problem 14P
Product A is made from components B and C. Item B, in turn, is made from D and E. Item C also is an intermediate item, made from F and H. Finally, intermediate item E is made from H and G. Note that item H has two parents. The following are item lead times:
- What lead time (in weeks) is needed to respond to a customer order for product A, assuming no existing inventories or
scheduled receipts? - What is the customer response time if all purchased items (i.e., D, F, G, and H) are in inventory?
- If you are allowed to keep just one purchased item in stock, which one would you choose?

Note that item H has two parents. Thefollowing are item lead times:a. What lead time (in weeks) is needed to respond to a cus-tomer order for product A, assuming no existing invento-ries or scheduled receipts?b. What is the customer response time if all purchased items(i.e., D, F, G, and H) are in inventory?c. If you are allowed to keep just one purchased item instock, which one would you choose?

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 size 55, 55, and 200 are used for Items C, D, and E, respectively. Items C, E, and F have on-hand (beginning) inventories of 10, 50, and 160, respectively; all other items have zero beginning inventory. We are scheduled to receive 10 units of A in Week 2, 60 units of E in Week 1, and also 50 units of F in Week 1. There are no other scheduled receipts. If 32 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
