The mean rate of arrival at an airport during the peak period is 20 planes per hour. The actual number of arrivals number of arrivals in any hour follows a poisson distribution. The airport can land 60 planes per hour on average in good weather and 30 planes per hour in bad weather. The number landed planes in any hour follows an exponential distribution. When there is congestion, the plane that arrives first, lands first. There is only one landing...

The emergency telephone (911) center in a large city receives an average of 120 calls per hour during a typical day. On average, each call requires about 121 seconds for a dispatcher to receive the emergency call, determine the nature and location of the problem, and send the required individuals (police, firefighters, or ambulance) to the scene. The center is currently staffed by 4 dispatchers a shift but must have an adequate number of dispatchers on duty and it has...
