The D/D/1 queuing model assumes deterministic arrival and departures withone departure channel; The M/D/1 queuing model assumes exponentially distributed arrival times,deterministic departure times, and one departure channel.QUEUING WITH CONSTANT ARRIVAL AND DEPARTURE RATESVehicles arrive at an entrance to a recreational park. There is a single gate(at which all vehicles must stop), where a park attendant distributes a freebrochure. The park opens at 8:00 AM, at which time vehicles begin to arriveat a rate of 480 veh/h.After 20 minutes the arrival flow rate declines to 120 veh/h, and itcontinues at that level for the remainder of the day.If the time required to distribute the brochure is 15 seconds, andassuming D/D/1 queuing, describe the operational characteristics of thequeue.
