A two-runway (one runway for landing, one runway for
taking off) airport is being designed for propeller-driven
aircraft.
a. Identify the customer and the server in the system!
b. The time to land an airplane is known to be
exponentially distributed, with a mean of 1.5 minutes. If
airplane arrivals are assumed to occur at random, what
arrival rate can be tolerated if the average wait in the sky
is not to exceed 3 minutes?
c. Assuming the arrival rate from problem b., compute the
steady-state average utilization of the server!
