Chapter 13, Problem 11P
Determine material requirements plans for pans N and V and subassembly I as described in Solved Problem 3 for each of the following:
a. Assume that there are currently 100 Ns on hand and scheduled receipts of 40 Is and 10 Vs at the beginning of week 3. No Es are on hand: 120 Es are needed at the start of week 5.
b. Assume on-hand and scheduled receipts as in part a. Now suppose that 100 Es are needed at the stmt of week 5 and 55 at the start of week 7. Also, use multiples of these order sizes: N, 800; V, 200. Use lot-for-lot ordering for I.
C. Using your answer to part b, update the MRP for V, using the following additional information for each of these cases: (1) one week has elapsed (making it the start of week 2), and (2) three weeks have elapsed (making it the start of week 4).
