1. There is never a queue in a system if customers are unwilling or unable to wait for service.
OTrue
OFalse
2. Economies of scale are demonstrated in an Erlang loss system because the number of servers increases as fast as the demand rate to maintain a particular level of denial of service probability.
OTrue
OFalse
3. A queuing model that applies to a queuing system where customers are unwilling or unable to wait for service is called the:
OCopenhagen model.
OKrarup model.
OLittle model.
OErlang loss model.
Homework Answers
Solution:
- True
If customers are unwilling to wait for the service in a queue then there will be no queue developed because the new customer will walk away when she finds out that all the servers are busy. Hence, the statement is true. - True
The demand rise results in the addition of more servers to ensure the quality and deliverability of the service remain unaffected and strong. Hence, the statement is true. - Erlang Loss Model:
Erlang loss model states that any customer who visits the server to find that all the servers are filled will be lost. Hence, the correct option is Erland Loss Model which states the same.

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...

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...
