The final assembly plant for the Mach 10 one-person sailboat is in Cupertino, California.  At this time only 200 minutes are available each day to meet a daily demand for 60 sailboats.

a)  Given the following information draw the precedence diagram and assign the tasks to the fewest workstations possible to meet the demand.
 
 

Task	Time	Precedents
A	1	-
B	1	A
C	2	A
D	1	C
E	3	C
F	1	C
G	1	D, E, F
H	2	B
I	1	G, H

b)  What is the efficiency of the line?

c)  Repeat the steps above with 300 minutes of assembly time available each day.  What is the efficiency of the line now?

d)  Repeat the steps above with 400 minutes of assembly time available each day.  What is the efficiency of the line now?
