Explanation / Answer

12) Cycle time = Available time / Demand = 8 * 60 * 5 / 400 = 6 min

13) Theoritical Workstation = Total processing time / Cycle Time = (4+3+1+5+3+2+3) / 6 = 3.5 ~ 4 numbers

14) C

15) Efficiency = Total processing time / ( no of workstations * cycle time) = 25 / ( 6* 5) = 83.33%
