You are product planner for product A (in Problem(A part structure, lead time (weeks), and on-handquantities for product A are shown in Figure 14. 14. From theinformation shown, generate:a) An indented bill of material fo r product A b) Net requirements for each part to produce I0 As in week 8using lot-for-lot. IP).) The field service manager, Mark Moon,has just called and told you that the requirements for B and Fshould each be increased by I 0 units for his repair requi rements inthe field.a) Prepare a list showing the quantity of each part required to produce the requirements for the service manager and the production request of I 0 Bs and Fs. b) Prepare a net requirement plan by date for the new requirements (for both production and field service), assuming that the field service manager wants his 10 units ofB and F in week 6 and the 10 production units of A in week 8.
The following table lists the components needed to assemble an end item, the manufacturing or purchase lead times (in weeks) for typical lot sizes, amount on hand, and the direct components of each item and, in brackets, the number of each component for each parent.

(You don’t need to develop the MRP tables.)Additional units c. An order for 44 units of the end item is scheduled to be shipped at the start of week 8. What is the latest week that the components of the order can be started and the order still be ready to ship on time? (You don’t need to develop the MRP tables.)The latest week
A partially completed inventory record for the motor subassembly is shown in Figure.a. Complete the last three rows of the record by using the L4L rule.b. Complete the last three rows of the record by using the POQ rule with P = 2.c. Complete the last three rows of the record by using the POQ rule with P = 2.d. If it costs the company $1 to hold a unit in inventory from one week to the next, and the cost to release an order is $50, which of the lot sizing rules used above will provide the lowest inventory holding + order release cost?
