Draw the precedence diagram. b. What is the workstation cycle time required to produce 240 units per day? c. Balance this line using the longest task time. Use largest number of following tasks as a secondary (tiebreaker) rule. You need to show all the assignments to the workstations and the order in which you assign task. d.
