Company is setting up an assembly line to produce cellular phones. They intend to use line balancing with the longest- task- time heuristic. They know the demand part per hour is 40 phones and the productive time per hour is 54 minutes. Displayed below is the data they have collected
Task time(in minutes) predecessors
A 0.40 none
B 1.20 A
C 0.90 A
D 0.70 B
E 0.60 B
F 0.35 C
G 1.00 D, E
H 0.80 F,G
I 0.50 H
