As the Cottrell Bicycle Co. of St. Louis completes plans for its new assembly line, it identifies 25different tasks in the production process. VP of Operations Jonathan Cottrell now faces the job ofbalancing the line. He lists precedences and provides time estimates for each step based on work-sampling techniques. His goal is to produce 1,000 bicycles per standard 40-hour workweek.TaskTime (sec)ImmediateTaskTime (sec)ImmediatePredecessorsPredecessorsK360E3109F3K424K3D653F4K927K3D772F9, E2, E3J166K3D878E3, D6J222K3 -D937D6J33C178F7G479K4, K9B372D7, D8, D9, C1G529К9, 1B5108C1F33212B718B3F492J2A152B5F721J3A272B5F9126G4A3114B7, A1, A2E218G5, F3a) Balance this operation using shortest operation time rule and compute the efficiency of the line.b) Discuss how this balance could be improved.
