Vehicles 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 free brochure. The park opens at 8:00 A.M., the average arrival rate be 240 veh/h and Poisson distributed (exponential times between arrivals) over the entire period from park opening time (8:00 A.M.) until closing at dusk. If the time required to distribute the brochure is 10 seconds, the distribution time varies depending on whether park patrons have questions relating to park operating policies, assuming M/M/1 queuing. a.) Compute the average length of queue (express in veh), b.) Average waiting time in the queue (express in min/veh), c.) and average time spent in the system(express in min/veh)

5-Vehicles start arriving for a booth in a parking lot to receive free brochures at 8:45 A.M at a uniform deterministic rate of 4 per minute and continue to arrive at this rate until 9:15 A.M. From 9:15 to 10:00 A.M. the arrival rate becomes 8 per minute. The brochures are distributed at a uniform deterministic rate of 11 cars per minute over the 45-minute time period only (from 9:15 A.M. until 10:00 A.M). Determine total delay, maximum queue length, and longest vehicle delay.

There is a single gate (at which all vehicles must stop), where a park attendant distributes a free brochure. The park opens at 08:00 am, at which time vehicles begin to arrive at a rate of 480 veh/hr. after 20 minutes the arrival flow rate declines at 120 veh/hr, and it continues at that level for the remainder of the day. If the time required to distribute the brochure is 15 seconds and assuming D/D/1 queue, a. Determine the maximum length of queue that occurred. b. How long did it take to dissipate the queue? c. What is the average delay per vehicle? Show all necessary solutions and diagram 2.) Consider the entrance to the recreational park described in the previous question. However, assuming that the average arrival rate is 180 veh/hr and Poisson-distributed (negative exponential…
