Wild Widget must set up an assembly line for widgets. Forecasts show that 68 units per hour should be produced. The tasks required, task times, and precedence relationships are as follows: TTT Task A B Time (seconds) 10 21 20 Predecessors A A 28 E 12 D 10 D G 40 E,F b. What is the takt time? (Round your answer to the nearest whole number.) Takt time seconds per unit c. What is the theoretical number of workstations? (Round up your answer to the next whole number.) Number of workstations d. Assign the tasks to the workstations to balance the line using the longest operating time rule. Workstation Time (Seconds) Idle Time (Seconds) Workstation Tasks in Order 1 2 3 e. What is the efficiency of the balanced line? (Round your answer to 1 decimal place.) Efficiency f. If demand decreased to 58 units per hour, what would be the new takt time? (Round your answer to the nearest whole number.) New takt time seconds/workstation
