Question: Consider a two workstation line, the first workstation has one machine and the second one has two machines. Arrival rate to the first workstation

Consider a two workstation line, the first workstation has one machine and the second one has two machines. Arrival rate to the first workstation is 8 jobs per hour, and the coefficient of variation of arrival time is 1 hour. The mean effective process time in each machine at both the workstations is 0.1 hour with a coefficient of variation of 1.6. Find a) SCV of the arrival time to workstation 2? [Hint: Think about "Propagation of Variability"] b) If the standard deviation of arrivals at station 2 is 1, what is the utilization for station 2? c) SCV of the departure time from workstation 2?
