vehicles start to arrive at a parking area at 6 am with an arrival rate function(vehicles per minute) of lambda(t)=1.2+(0.3)t, where t is in minutes. At 6:15 am, the parking area opens and processed vehicles at a rate of 12 per minute.
a)Determine when does the queue clear?
b)find the total delay?
c)find the maximum queue length?
Vehicles arrive at a single toll booth beginning at 7:00 A.M. at a rate of 8 veh/min. Service also starts at 7:00 A.M. at a rate of u(t)=6+0.2t where (f) is in vehicles per minute and it is in minutes after 7:00 A.M. Assuming D/D/1 queuing, determine when the queue will clear, the total delay, and the maximum queue length in vehicles.
Vehicles arrive to the park entrance at a constant rate of 900 veh/hour from
7:30 AM to 8:10 AM and then at a constant rate of 600 veh/hour from 8:10 A.M.
The park opens at 8:10 A.M. and the manager wants to set the departure rate so that the average delay per vehicle (i.e.:
Total delay/total number of arrival) is no greater than 24 minutes (measured from the time of the first arrival until the total queue clears).
Assuming D/D/1 queuing, what is the minimum departure rate (?) needed to achieve this?
What is the total delay at this rate?
What is the longest Queue?
