I am having difficulty with this assignment:

Task	Task Time (Min.)	Preceding tasks
A	1
E	2	-
B	3	A
C	1	B
D	4	A,E
F	3	C,D
	Sum = 14

a) Draw the precedence diagram in your scratch sheet.

b) Cycle time (minutes)? ____________

c)N_t = ____________________

d) Balance the line (that is, assign tasks to stations) using the "longest operations time" heuristic (write in small letter to accommodate multiple lines in each station).

Station	Task	Task Time (min)	Time Remaining (minutes)	Tasks Ready
		i)	ii)	iii)

e) Efficiency of the assembly line =
