The following table lists the components needed to assemble an end item, lead times (in weeks), and quantities on hand.

Item	Lead Time	Amount on Hand	Direct Components
End	1	-	L(2), C(1), K(3)
L	2	10	B(2), J(3)
C	3	15	G(2), B(2)
K	3	20	H(4), B(2)
B	2	30
J	3	30
G	3	5
H	2	0

a) If 45 units of the End item are to be assembled, additional units of item B will be needed. (Hint: You dont need to develop an MRP plan, but you WILL NEED to create a product structure tree)

b) An order for the end item is scheduled to be shipped at the start of week 8. Week # is the latest week that the order can be started and still be ready to ship on time? (Hint: You don't need to develop an MRP plan for this part either. You can create an assembly time chart by drawing your product structure tree sideways)
