(0) Consider two digital fuel pumps A and B that could be used in a single gas station. Pump A has a mean effective process time of 4 min. With a squared - coefficient of variation of .5. Pump B has a mean affective time of 3 min. With a squared- coefficient of variation of 5.Assume that the arrival rate of cars is .2 car per min. With a squared-coefficient of variation of 1. Which pump will have a longer average cycle time? Hint the number of machines, m, is 1. Now assume that the number of pumps in the gas station could be 3(3 pumps of A or 3 pumps of B). What will happen to cycle time if the arrival rate of cars is doubled
