- In queuing system 1.- What is the average Queue lenght ? What is the expected waiting time ? 2.-1.) What is not considered a measure of system performance in a queuing analysis? average number waiting in line service time system utilization average number in the system 2.) Which of the following is true of a customer who reneges? after joining the queue, becomes impatient and leaves tries to get through as quickly as possible by moving from queue to queue never returns after going through the queue refuses to join the queue because it is too long13. Suppose AirOM passengers arrive to the check-in desk every 100 seconds (on average). The desk is staffed by a single ticketing agent, who takes 1.4 minutes (on average) to process a passenger. The arrivals follow a Poisson process and the service time is distributed exponentially. What is a passenger’s average waiting time (in seconds)? Enter a single number as your answer. If your final number is not integer, keep two decimal places in your answer.
- In a waiting line situation, arrivals occur at a rate of 2 per minute, and the service times average 18 seconds. Assume the Poisson and exponential distributions. a. What is λ? b. What is μ? c. Find probability of no units in the system. d. Find average number of units in the system. e. Find average time in the waiting line. f. Find average time in the system. g. Find probability that there is one person waiting. h. Find probability an arrival will have to wait. Please show a corrct solution and answer. Thank you.At a border inspection station, vehicles arrive at the rate of 8 per hour in a Poisson distribution. For simplicity in this problem, assume that there is only one lane and one inspector, who can inspect vehicles at the rate of 15 per hour in an exponentially distributed fashion. a. What is the average length of the waiting line? (Round your answer to 2 decimal places.) b. What is the average time that a vehicle must wait to get through the system? (Round your answer to 2 decimal places.) c. What is the utilization of the inspector? (Round your answer to 1 decimal place.) d. What is the probability that when you arrive there will be three or more vehicles ahead of you? (Round your answer to 1 decimal place.)27. Customers enter the waiting line to pay for food as they leave a cafeteria on a first-come, first-served basis. The arrival rate follows a Poisson distribution, while service times follow an exponential distribution. If the average number of arrivals is two per minute and the average service rate of a single server is five per minute, what portion of the time is there less than 3 people in line? Answer to three decimal points please and thank you
- 1.) What does not decrease system utilization? increase in arrival rate increase in service rate increase in the number of servers decrease in the service time 2.) When a customer is waiting in line and decides to leave a system, this is known as anti-queuing reneging jockeying hesitatingPaula Caplin is manager of a major electronics repair facilityowned by Fisher Electronics. Recently, top management ex-pressed concern over the growth in the number of repair jobs in process at the facility. The average arrival rate is 120 jobsper day. The average job spends four days at the facility.a. What is the current work-in-process level at the facility?b. Suppose that top management has put a limit of one-halfthe current level of work-in-process. What goal mustPaula establish, and how might she accomplish it?At a border inspection station, vehicles arrive at the rate of 10 per hour in a Poisson distribution. For simplicity in this problem, assume that there is only one lane and one inspector, who can inspect vehicles at the rate of 15 per hour in an exponentially distributed fashion. a. What is the average length of the waiting line? (Round your answer to 2 decimal places.) b. What is the average total time it takes for a vehicle to get through the system? (Round your answer to 2 decimal places.) c. What is the utilization of the inspector? (Round your answer to 1 decimal place.) d.

Answer to three decimal points. thanks!92 Benny the Barber owns a one-chair shop. At barber college, they told Benny that his customers would exhibit a Poisson arrival distribution and that he would provide an exponential service distribution. His market survey data indicate that customers arrive at a rate of 2.5 per hour. It will take Benny an average of 20 minutes to give a haircut. Based on these figures, find the following: a. The average number of customers waiting Note: Round your intermediate calculations to 3 decimal places and final answer to 2 decimal places. b. The average time a customer waits. Note: Round your answer to 2 decimal places. c. The average time a customer is in the shop.
