TASK 2
a) Based on the product structure tree above, determine Bills of Materials (BOM) for the
quantities of B, C, D, E, and F needed to assemble 650 X's, if you have the following
in inventory:
Component
On Hand Inventory
B
150
C
85
D
67
E
114
ANSWER :
B: 2 X 650 = 1300
C : 1 X 650 = 650
-150
– 85
= 1150
= 565
D : 3 X 1150 = 3450
-67
E : 1 x 1150 = 1150
E : 2 x 565 = 1130
F : 2 x 565 = 1130
= 3383
E : 4 X 3383 = 13,532
-114
= 13,418
Thus, given the amounts of on-hand inventory, 650 X will require:
B: 1150
E: 15,698 (=13,418 + 1150 + 1130)
D: 3383
F: 1130
C: 565
b) Consider the two product structure trees shown above, develop a MRP for item D. Given that
the master schedule calls for 780 units of A in week 4 and 1850 units of C in week 6. There is
a beginning inventory of 390 units of D on hand and all items have lead times of ONE week.
