Customers arrive at a suburban ticket outlet at the rate of 4 per hour on Monday mornings. This can be described by a Poisson distribution. Selling the tickets and providing general information takes an average of 12 minutes per customer, and varies exponentially. There is 1 ticket agent on duty on Mondays. Determine the System Utilization Question 12 options: .8 1.6 .4 .88 None of the Above Question 13 (1.5 points) Customers arrive at a suburban ticket outlet at the...

1. A waiting line problem has an average of 80 arrivals per eight hour day. Suppose there is a single server and the average service time is 8 minutes. The average service rate is a) 8 per minute. b) 8 minutes. c) 10 per day. d) 10 per hour. e) 24 per hour f) none of the above. 2. A waiting line problem has an average of 80 arrivals per hour. Suppose each server can serve one customer every 4...
SHOW ALL WORK! In a waiting line situation, arrivals occur at a rate of 2 per minute, and the service times average 24 seconds. Assume the Poisson and exponential distributions. a. What is λ? What is μ? b. Find average number of units in the system. c. Find average time in the waiting line. d. Find probability that there is one person waiting. e. Find probability an arrival will have to wait.
1. A new shopping mall is considering setting up a car wash manned by six employees. From past data, Regal Car Wash estimates that dirty cars arrive at the rate of 10 per hour all day Saturday. With a crew working the wash line, Regal figures that cars can be cleaned at the rate of one every 5 minutes. One car at a time is cleaned in this example of a single-channel waiting line. It is assumed that arrivals are...
Problem 1 REGIONAL AIRLINES Regional Airlines is establishing a new telephone system for handling flight reservations. During the 10:00 A.M. to 11:00 A.M. time period, calls to the reservation agent occur ran- domly at an average of one call every 3.75 minutes. Historical service time data show that a reservation agent spends an average of 3 minutes with each customer. The waiting line model assumptions of Poisson arrivals and exponential service times appear reasonable for the telephone reservation system. Regional...

4. When John enters the bank office, there are four customers waiting in line and one customer is being served. There is a single clerk and the service time is exponentially distributed with λ-10 customer per hour, independent of everything else. (a) (2 points) What is the average service time per customer? (b) (4 points) What is the distribution of John's waiting time? (c) (4 points) Calculate the expected value and variance of John's waiting time. (d) (10 points) It...
The school of business at abc university has a information desk manned by one student worker. It takes him an average of 3 minutes to answer questions raised by guests who visit the school building. Guests arrive at the desk at the rate of 15 per hour. Suppose that arrivals are Poisson and the service times are exponentially distributed. A. What is the average waiting time in queue? B. Suppose the worker earns $7.25 per hour. The cost of waiting...
Consider a simple queuing system in which customers arrive randomly such that the time between successive arrivals is exponentially distributed with a rate parameter l = 2.8 per minute. The service time, that is the time it takes to serve each customer is also Exponentially distributed with a rate parameter m = 3 per minute. Create a Matlab simulation to model the above queuing system by randomly sampling time between arrivals and service times from the Exponential Distribution. If a...
