Explanation / Answer
Part 1: (B) 1
Statement 1. Scheduled receipts are the same as planned receipts - INCORRECT (scheduled receipts are given variables, not planned variables, whereas planned receipts are planned as a part of MRP)
Statement 2. The IRF contains the product structure of the end-item - INCORRECT (IRF is inventory records of items. It is the BOM which contains the product structure.)
Statement 3. The POR is the inventory policy of the MRP - CORRECT
Statement 4. MRP minimizes cost - INCORRECT (cost minimization is not an objective of MRP)
Part 2
Question 2. Qd will be 3 or its multiple. So, Qd=6 for MRP C is correct.
Question 3. Qd=7+ for MRP D only. So, MRP D is correct
Question 4. For Qd=LFL, MRP B is correct because, with Qd=5, the PSB at last day becomes exactly 8 (=SS). Otherwise, this would have been 3 which is less than SS.
Part 3
Statement 1. The inventory on hand for May 2 is 157 - CORRECT
Statement 2. The planned order release for May 3 is 10 - INCORRECT (it is 30)
Statement 3. The net requirements for May 4 is 17 - INCORRECT (it is 16+11=27)
Statement 4. The project stock balance for May 5 is 16 - INCORRECT (it is 17)
So, only one statement is correct.
