TheproductionlineofproductXisdescribed below.504units ofproductXmustbeproduced daily with production time being 7 hours per day. Design a line that minimized the number ofworkstations based on the cycle time and the precedence of thetasks.

Task	Task Time (Seconds)	Immediate predecessor
A	45	-
B	11	A
C	9	B
D	50	-
E	26	D
F	11	E
G	12	C
H	10	C
I	9	F, G, H
J	10	I

1. Draw a precedencediagram
2. Calculate cycletime.
3. Calculate the minimum number ofworkstations.
4. Balance the assembly line using maximum number of followers, in case of a tie use highest positionalweight.
5. Calculate Efficiency of theline.
6. Calculate idle time inseconds.
