5. 9 points) If a second engineer, Nadim, was hired to repair monitors. Two scenarios are considered. In the first scenario Rabih will receive on average half of the monitors and Nadim the other half. Each of them will have its own queue of monitors. In the second scenario all monitors arrive to one queue and each engineer work on whichever monitor is next in Line. What is the utilization in each scenario? What is the average time a monitor waits for repair in each scenario? Is there a better scenario from a waiting time point of view? Explain carefully your calculations. Compare both scenarios. Conclude 6- (4 points) Suppose that the number of returned monitors increased 5 times (i.e. to 60 monitors per day). How many engineers repairing the monitors would the company need, so that the inventory of monitors does not build up indefinitely? Assume that all engineers would repair monitors as quickly as Rabih. 5. 9 points) If a second engineer, Nadim, was hired to repair monitors. Two scenarios are considered.
