Figure 16.40 illustrates the BOM for product A. The MPS  start row in the master production schedule for product A calls for 50 units in week 2, 65 units in week 5, and 80 units  in week 8. Item C is produced to make A and to meet the  forecasted demand for replacement parts. Past replace- ment part demand has been 20 units per week (add 20 units to C’s gross requirements). The lead times for items F   and C are 1 week, and for the other items the lead time is  2 weeks. No safety stock is required for items B, C, D, E,   and F. The L4L lot-sizing rule is used for items B and F;  the POQ lot-sizing rule (P= 3) is used for C. Item E has  an FOQ of 600 units, and D has an FOQ of 250 units. On- hand inventories are 50 units of B, 50 units of C, 120 units  of D, 70 units of E, and 250 units of F. Item B has a sched- uled receipt of 50 units in week 2. Develop a material re-quirements plan for the next 8 weeks for items B, C, D, E,   and F.
