Concept explainers
Vehicles begin to arrive at a parking lot at 7:45 A.M. at a constant rate of 4 veh/min and continue to arrive at that rate throughout the day. The parking lot opens at 8:00 A.M. and vehicles are processed at a constant rate of one vehicle every 10 seconds. Assuming D/D/1 queuing, what is the longest queue, the queue at 8:15 A.M., and the average delay per vehicle from 7:45 A.M. until the queue clears?

- Vehicles arrive at a single toll booth beginning at 8:00 AM. They arrive and depart according to a uniform deterministic distribution. However, the toll booth does not open until 8:10 AM. The average arrival rate is 8 veh/min and the average departure rate is 10 veh/min. Assuming D/D/1 queuing, when does the initial queue clear and what are the total delay, the average delay per vehicle, longest queue length (in vehicles), and the wait time of the 100th vehicle to arrive (arrow_forwardVehicles 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?arrow_forwardehicles arrive at a single toll booth beginning at 8:00 A.M. They arrive and depart according to a uniform deterministic distribution.

Vehicles start arriving at 6:00 P.M., and when the queue reaches 36 vehicles, service begins. The company policy states that the total vehicle delay should be equal to 500 veh-min. Assuming D/D/1 queuing and a constant service rate, at what time did the queue clear?arrow_forwardA toll booth on a temple is open from 8:00 AM to 12 midnight. Vehicles start arriving at 7:45 AM at a uniform deterministic rate of six per minute until 8:15 AM and from then on at two per minute. If vehicles are processed at a uniform deterministic rate of six per minute, determine the (a) time of queue dissipation in minutes (b) total number of vehicles in queue and (c) total vehicle delayarrow_forward
- The arrival rate at a parking lot is 6 veh/min. Vehicles start arriving at 6:00 P.M., and when the queue reaches 36 vehicles, service begins. The company policy states that the total vehicle delay should be equal to 500 veh-min. Assuming D/D/1 queuing and a constant service rate, determine the average delay of any vehicle.arrow_forwardAt 8:00 A.M. there are 10 vehicles in a queue at a toll booth and vehicles are arriving at a rate of (t) = 6.9 − 0.2t. Beginning at 8 A.M., vehicles are being serviced at a rate of (t) = 2.1 + 0.3t ((t) and (t) are in vehicles per minute and t is in minutes after 8:00 A.M.). Assuming D/D/1 queuing, what is the maximum queue length, and what would the total delay be from 8:00 A.M. until the queue clears?arrow_forwardAt 8:00 A.M. there are 10 vehicles in a queue at a toll booth and vehicles are arriving at a rate of (t) = 6.9 − 0.2t.

- A. There is a traffic accident happened on highway at 6:00 AM the flow rate on that time was 50 veh per min while the normal capacity of highway is 60 veh per min but since there is an accident, it reduced to 22 veh per min, the traffic was cleared after 25 minutes. Determine the length of the queue before the removal of blockage. Also calculate the time that vehicles waited a long line before the removal of blockage and when was the queue cleared?arrow_forwardVehicles arrive at the carpark of an airport. Vehicles have to queue at the single entrance gate of the carpark at 9:00 AM. The arrival rate is constant at 240 veh/hr. However, between 9:00 and 9:40 AM, the parking ticket machine at the entrance works slowly due to a malfunction, and consequently, each vehicle spends 30 seconds to take the parking ticket. After 9:40 AM, the problem is solved and vehicles spend only 10 seconds at the gate to take the ticket. In how many minutes does the queue dissipate? Select one: a. 60 b. 70 c. 75 d. 80arrow_forwardAt 9 am, vehicles arrive at a toll booth facility at the rate of 480 vehicles/hour. Initially, the toll booth is closed from 9:00 am until 9:15 am. Then it opens from 9:15 with a service rate of 600 vehicles/hour. Assuming D/D/1 queuing, determine: (1) At what time queue disappears? (2) What is the total delay? (3) What is the maximum Queue length? (4) What is the queue length at 10:00 am? (5) What is maximum delay? (6) What is the delay for 160th vehicle?arrow_forward
