Question 1

Which of the following is not considered to be an element of a waiting line system?
A) the customer population source
B) the service system
C) the average number of customers waiting in line
D) the arrival and service patterns
E) the priorities used for controlling the line

Accepted Answer

The average number of customers waiting in line is a performance measure of a waiting line system, not an element. The elements include the customer population source, the service system, the arrival and service patterns, and the priorities used for controlling the line.

Question 2

Which of the following is not considered to be an element of a waiting line system?
A) the customer population source
B) the service system
C) the average number of customers in the system
D) the arrival and service patterns
E) the priorities used for controlling the line

Accepted Answer

The average number of customers in the system is not an element of a waiting line system, but rather a performance measure or statistic used to evaluate the system's efficiency. The elements of a waiting line system include the customer population source, the service system, the arrival and service patterns, and the priorities used for controlling the line.

Question 3

One challenge in designing waiting lines is to obtain service systems with _______ but not ______ amounts of capacity.
A) adequate, excessive
B) adequate, expensive
C) low cost, cheap
D) justifiable, noticeable
E) infinite, excessive

Accepted Answer

The challenge in designing waiting lines is to strike a balance between having enough capacity to efficiently serve customers yet not creating too much excess capacity that is costly and unnecessary. Therefore, the best choice is A - having adequate capacity but not excessive amounts of capacity.

Question 4

A single-line, multiple-server system has _____ ______ in terms of waiting times than the same system with a line for each server.
A) poorer performance
B) similar performance
C) better performance
D) comparable performance
E) reduced performance

Accepted Answer

A single-line, multiple-server system (also known as a queue with parallel servers) has better performance in terms of waiting times than the same system with a line for each server (also known as a queue with dedicated servers). In a single-line system, customers are served by whichever server becomes available first, reducing the overall average waiting time. In a multiple-line system, one line may have more customers waiting than another, resulting in longer wait times for some customers.

Question 5

A customer population is called _______________ when the number of potential new customers is affected by the number of customers already in the system.
A) finite
B) infinite
C) dependent
D) independent
E) biased

Accepted Answer

A customer population is called finite when the number of potential new customers is affected by the number of customers already in the system. This means that the number of potential customers is limited and can be counted. The other options do not accurately describe a customer population that is affected by the number of customers already in the system.

Question 6

What occurs when a customer enters a waiting line but decides to exit before being served?
A) balking
B) walking
C) reneging
D) vacillating
E) jockeying

Accepted Answer

This phenomenon is referred to as "reneging".

Question 7

Which of the following is least likely to be considered a finite customer population?
A) subassemblies in a just-in-time manufacturing environment
B) fast food restaurant employees waiting to use the restroom
C) planes waiting to take off at an airport
D) a class of 10 students who might visit their professor during office hours
E) cars taking Exit 76 off of a freeway during rush hour

Accepted Answer

Cars taking Exit 76 off of a freeway during rush hour represent a scenario where the population can vary widely and is not easily quantifiable ahead of time, making it least likely to be considered finite compared to the other options where the populations are more clearly defined and limited.

Question 8

Which of the following is least likely to be considered a finite customer population?
A) subassemblies in a just-in-time manufacturing environment
B) fast food restaurant employees waiting to use the restroom
C) planes waiting to take off at an airport
D) customers in a grocery store
E) a class of 10 students who might visit their professor during office hours

Accepted Answer

The population of customers in a grocery store is least likely to be considered finite because it can vary widely and is not restricted to a specific, countable number at any given time, unlike the other options which have a more clearly defined and limited set of individuals or items.

Question 9

Which of the following is least likely to be considered an infinite customer population?
A) subassemblies in a just-in-time manufacturing environment
B) customers in an amusement park
C) a class of 500 students who might visit their professor during office hours
D) customers in a grocery store
E) cars taking Exit 76 off of a freeway during rush hour

Accepted Answer

Subassemblies in a just-in-time manufacturing environment are typically produced and used in a controlled, finite manner, unlike the other options which involve potentially large and unpredictable numbers of people or vehicles.

Question 10

Which of the following is least likely to be considered a finite customer population?
A) subassemblies in a just-in-time manufacturing environment
B) customers in an amusement park
C) fast food restaurant employees waiting to use the restroom
D) planes waiting to take off at an airport
E) a class of 10 students who might visit their professor during office hours

Accepted Answer

Customers in an amusement park are least likely to be considered a finite customer population because the number of customers can vary widely throughout the day and is not fixed or limited to a small, countable number.

Question 11

Which of the following is not considered to be an element of a waiting line system?
A) the customer population source
B) the service system
C) the arrival and service patterns
D) the priorities used for controlling the line
E) the system utilization rate

Accepted Answer

The elements of a waiting line system include the customer population source, the service system, the arrival and service patterns, and the priorities used for controlling the line. System utilization rate is not considered an element, but rather a performance measure of the system.

Question 12

Which of the following is least likely to be considered an infinite customer population?
A) customers in an amusement park
B) a class of 500 students who might visit their professor during office hours
C) customers in a grocery store
D) planes waiting to take off at an airport
E) cars taking Exit 76 off of a freeway during rush hour

Accepted Answer

Question 14

Which of the following is least likely to be considered an infinite customer population?
A) customers in an amusement park
B) a class of 500 students who might visit their professor during office hours
C) a class of 10 students who might visit their professor during office hours
D) customers in a grocery store
E) cars taking Exit 76 off of a freeway during rush hour

Accepted Answer

A population that is limited to a specific number, such as a class of only 10 students, is least likely to be considered infinite. The other options have a greater potential to be considered infinite as they do not have a specific limit on the number of possible customers.

Question 15

A customer population is called _______________ when the number of potential new customers is not affected by the number of customers already in the system.
A) finite
B) infinite
C) dependent
D) independent
E) unbiased

Accepted Answer

An infinite customer population is one where the number of potential new customers is not affected by the number of customers already in the system. This is in contrast to a finite population, where the number of potential new customers is limited or impacted by the number of existing customers in the system. Dependent and independent are not accurate terms to describe a customer population, and unbiased is not relevant in this context.

Question 16

What occurs when a customer decides not to enter the waiting line?
A) vacillating
B) walking
C) reneging
D) balking
E) jockeying

Accepted Answer

Balking occurs when a customer decides not to enter the waiting line upon seeing its length or the wait time, choosing instead to leave.

Question 17

Which of the following is not considered to be an element of a waiting line system?
A) the priorities used for controlling the line
B) the customer population source
C) the service system
D) the arrival and service patterns
E) the average amount of time customers spend waiting

Accepted Answer

The average amount of time customers spend waiting is a performance measure or outcome of a waiting line system, not an element of the system itself. Elements of a waiting line system include factors that define or influence the structure and function of the system, such as the customer population source, the service system, the arrival and service patterns, and the priorities used for controlling the line.

Question 18

What occurs when a customer enters one line and then switches to a different line in an effort to reduce his or her waiting time?
A) balking
B) walking
C) reneging
D) vacillating
E) jockeying

Accepted Answer

Jockeying refers to the behavior of customers switching lines or queues in an attempt to reduce their waiting time.

Question 19

Which of the following is not considered to be an element of a waiting line system?
A) the customer population source
B) the service system
C) the arrival and service patterns
D) the average amount of time a customer spends in the system
E) the priorities used for controlling the line

Accepted Answer

The average amount of time a customer spends in the system is a performance measure or metric of the waiting line system but not considered an element of the system itself. The elements of a waiting line system include the customer population source, the service system, the arrival and service patterns, and the priorities used for controlling the line.
