Given the following Operating Characteristics from a queuing model with time units specified in hours, answer the five questions: Po = 0.4000 Lq = 0.9000 L = 1.5000 Wq = 0.2000 W = 0.3000 Pw = 0.6000 What is the average time, in minutes, a customer waits in line before being served? What is the average time, in minutes, a customer spends waiting and being served? What is the average number of customers in the system? What is the probability that there are no customers in the system? If the system serves a customer every 4 minutes, what is the service rate?

Consider a base case where a customer arrives every 40 seconds and the Customer Service Champion can handle 120 customers per hour. There are two Food Champions, each capable of handling 100 orders per hour How long should it take to be served by the restaurant (from the time a customer enters the kiosk queue until her food is delivered)? Use queuing models to estimate this.
In queuing theory and modeling, if 1/μ represents mean service time. Whatdoes μ represent? Service rateInterarrival time Arrival rate None
A queuing model that follows the M/M/1 assumptions has λ = 2 and μ = 8. The average number in the system Ls is ________ and the utilization of the system is ________.
In a queueing system, customers arrive once every 4 minutes (standard deviation = 7) and services take 3 minutes (standard deviation = 5.5). (Do not round intermediate calculations. Round your answer to three decimal places.) What is the average time a customer will spend in the queue (in minutes)? minutes
Which of the following is not a valid queuing model based on the Kendall notation? Select one: A. M/M/0 B. M/M/3 C. D/M/1 D. G/D/1- E. D/D/2
Which of the following cost estimates and the performance measures are used for economic analysis of a queuing system? Average waiting time of customers in the system Unit service rate is faster than arrival rate Average queue time in the system Average number of customers in the system
In waiting line management, system performance measures include which of the following: I. an arriving customer will have to wait. II. The average number of customers waiting. III. The average time customers spend in the system. IV The probability that the server is busy. Select one: a. II, III & IV b. I, II & III c. I, II & IV d. I, III & IV convert inputs into outputs; they are at the core of operations management. Select one: a. processes b. decisions C. resources d. products оооо
In an M/M/1 queueing system, the arrival rate is 5 customers per hour and the service rate is 7 customers per hour. If the service process is automated (resulting in no variation in service times but the same service rate), what will be the resulting performance measurements? What is the utilization? What is the expected number of customers in the system (L)? What is the expected waiting time (in hours) for the system (W)? What is the expected number of customers in the queue (Lq)? What is the expected waiting time (in hours) in the queue (Wq)?
