The random numbers represent critical values (z)
Simulation of operating time of operation 1 = m + z*s = 120 + 0.19*10 = 121.9 minutes
Simulation of operating time of operation 2 = m + z*s = 120 - 0.16*10 = 118.4 minutes
Simulation of operating time of operation 3 = m + z*s = 120 - 0.09*10 = 119.1 minutes
Simulation of operating time of operation 4 = m + z*s = 120 + 0.33*10 = 123.3 minutes
Simulation of operating time of operation 5 = m + z*s = 120 - 1.76*10 = 102.4 minutes
Simulation of operating time of operation 6 = m + z*s = 120 - 0.52*10 = 114.8 minutes
Simulation of operating time of operation 7 = m + z*s = 120 - 0.31*10 = 116.9 minutes
Simulation of operating time of operation 8 = m + z*s = 120 - 1.04*10 = 109.6 minutes
Simulation of operating time of operation 9 = m + z*s = 120 + 0.12*10 = 121.2 minutes
Model average time = 120 minutes.
Simulated times are randomly and normally distributed around the model average time.
