1)

The major difference between the finite and "infinite"-source queuing models is that for the finite source model:

Multiple Choice

• You cannot add additional servers.

• The arrival rate is affected by the length of the waiting line.

• There is no variability in the rate of arrivals.

• Only applies to single server systems.

2)

Queuing theory can be applied to analyze which type of service processes?

Multiple Choice

• Work-in-process inventory at the bottleneck stage of a manufacturing process

• Telephone calls made to a customer service call centre

• All of the choices

• Purchasing tickets or concessions at a movie theatre

3)

Replacing all of the components before failure is an example of what type of replacement decision?

Multiple Choice

• Total

• Encompassing

• Complete

• Group

4)

A reason that processing on a first-come, first-served (FCFS) basis may not be used in a multiple server queuing system is

Multiple Choice

• the cost (implications) of waiting may not be equivalent for all customers.

• the average wait will be shorter if separate lines are created for each server.

• None of these choices

• FCFS will always result in the lowest server utilization rate.

5)

For infinite source systems, server utilization equals the service rate divided by the arrival rate.

Multiple Choice

• False

• True
