Answer #1

Output = 40 units

Shift time = 8 hours or 480 minutes

Cycle time= Shift time / Output = 480/40 = 12 minutes

Sum of all task times = 46 minutes

Theoretical minimum number of stations = 46 / 12 = ~4 workstations

Idle time when there are 4+1 = 5 Workstations = Sum of task time / Number of workstations * Cycle time = 46 / (5*12) = 46/60 = 76.67%
