Question 1

The Monte Carlo technique is a mathematical model used within a simulation.

Accepted Answer

The Monte Carlo technique is a mathematical model used within a simulation to generate random samples for statistical analysis.

Question 2

Simulation analysis is the preferred method used at hospitals to determine the type of treatment a patient requires.

Accepted Answer

Simulation analysis is not necessarily the preferred method used at hospitals to determine the type of treatment a patient requires. Other methods such as diagnostic tests, physical examinations, medical history, and consultation with specialists may be used as well.

Question 3

An advantage of using a computer versus a manual approach when performing a simulation is that it often takes only seconds versus hours to reach a steady-state result.

Accepted Answer

Computers can perform calculations much faster than humans, allowing simulations to reach steady-state results much quicker than a manual approach.

Question 4

At a Walmart store,simulation can be used to analyze waiting lines at check-out stands to determine the required staffing levels.

Accepted Answer

Simulation can be used to analyze waiting lines and determine required staffing levels in a Walmart store.

Question 5

Simulation is a popular decision-making tool that provides a solution to any type of problem.

Accepted Answer

The answer of Simulation is a popular decision-making tool that...

Question 6

Simulation is the preferred technique for problems with random variables represented by probability distributions.

Accepted Answer

Simulation is commonly used to model and analyze systems with uncertainty, including those with random variables represented by probability distributions.

Question 7

A random number's likelihood of being selected is based on a normal distribution.

Accepted Answer

The answer of A random number's likelihood of being selected...

Question 8

Because simulation is used to analyze probabilistic problems,it provides information that is used to make a decision versus an optimal solution.

Accepted Answer

Simulation provides information based on probabilities and uncertainties, which can be used to make informed decisions rather than finding a single optimal solution.

Question 9

The Monte Carlo technique selects numbers randomly from a probability distribution for use in a quantitative model.

Accepted Answer

The answer of The Monte Carlo technique selects numbers randomly...

Question 10

Simulation analysis is useful for operational problems that
A)are easy to solve analytically.
B)can't be solved analytically.
C)require an optimal solution.
D)meet specific analytical criteria.

Accepted Answer

Simulation analysis is used for problems that cannot be solved analytically or are too complex to solve analytically. Simulation allows for the exploration of different scenarios and inputs to observe their impact on the system being modeled. Therefore, option B is the correct choice.

Question 11

A steady state results when a simulation is repeated enough times that the random variable being investigated reaches an average result that remains constant.

Accepted Answer

This is the definition of a steady state.

Question 12

Simulation is often viewed as the technique of last resort because it can be applied to situations when there is no applicable quantitative model.

Accepted Answer

The answer of Simulation is often viewed as the technique...

Question 13

As a simulation model becomes more complex,using a computer application is virtually impossible.

Accepted Answer

The use of computer applications actually becomes more necessary as a simulation model becomes more complex, as it allows for faster and more accurate calculations and analysis.

Question 14

The ___ technique selects numbers randomly from a probability distribution for use in a trial run of a simulation.
A)Computer World
B)Monaco
C)steady-state
D)none of the above

Accepted Answer

The correct term is "Monte Carlo" technique, which is not listed among the options.

Question 15

After a sufficient number of simulation runs,a steady state results when the variable being investigated reaches an ___ value that remains constant.
A)optimal
B)average
C)expected
D)estimated

Accepted Answer

A steady state typically refers to a state where the system being studied has reached a consistent, average value. Option A (optimal) suggests that the system is at its best possible state, which may not necessarily be steady. Option C (expected) and Option D (estimated) suggest a predictive component, while the question only asks about a current state.
