Question 2. (15 points) Consider the mrp-BOM in the figure below. Also, the planned order release (POR) calculations for A, C and D have already been calculated and given in the table below. Complete the table by calculating the gross requirements (GR) for products B and D. You must show your partial calculations. Hint: LFL = lot-for-lot lot sizing rule; Determine the when LFL is used, one must plan to produce only the units required (i.e, there is no lot-size restriction). A (1, 1, LFL) KEY: (quantity, LT, Lot size) B (5, 2, LFL) (3, 1, LFL) (1, 3, LFL) D (2, 2, LFL) B Week 1 Week 2 Week 3 Week 4 Week 5 POR for A 0 0 34 0 56 POR for C 0 45 22 0 0 POR for D 13 29 0 73 0 Gross Req. for B Gross Req. for D
