1. Solve this Line Balancing Math. (7 marks) Tasks Immediate Predecessor Task Time (in minutes) A - 0.3 B A 0.4 C B 0.5 D - 0.4 E D 0.8 F C, E 0.4 G F 0.6

a) Draw a precedence diagram and mark the workstation assigned to each task. (1.5 marks) b) Assuming a 600 minutes workday. Compute the cycle time needed to obtain an output of 470 units per day. (.5 mark) c) Determine the minimum no of workstation required. (.5 mark) d) Assign task to workstations using this rule: (3.5 marks) i. Assign task according to the greatest positional weight. ii. In case of a tie, use the tiebreaker of assigning the task with the greatest number of following tasks. e) Compute Percent Idle time and Efficiency. (.5+ .5 = 1 marks)
