UNIQUE MULTIPLE CHOICE QUESTIONS
AND ANSWERS WITH DETAILED
RATIONALES LATEST UPDATE
Question 1
Which of the following is the BEST definition of a simulation model?
A) A mathematical equation that exactly predicts system behavior
B) A highlevel representation of the operation of a real world process or system
C) A physical replica of a system used for testing
D) A statistical test for hypothesis validation
Answer: B
Rationale: A simulation model is a highlevel representation of the operation of a
real world process or system. It is not an exact predictor (A), nor necessarily a
physical replica (C), nor a statistical test (D). Simulation models can be discrete or
continuous, stochastic or deterministic.
Question 2
What is the primary advantage of simulation over analytical models?
A) Simulation always produces more accurate results
1
, B) Simulation can study models too complicated for analytical/numerical
treatment
C) Simulation requires less computational time
D) Simulation eliminates all sources of error
Answer: B
Rationale: Simulation can study models too complicated for analytical or
numerical treatment and can examine detailed relations that might be lost in
analytical or numerical approaches. Simulation does not always produce more
accurate results (A), requires significant computational time (C), and cannot
eliminate all sources of error (D).
Question 3
Which type of system changes its state only at discrete points in time?
A) Continuous system
B) Deterministic system
C) Discreteevent dynamic system
D) Static system
Answer: C
Rationale: Discreteevent dynamic systems change state only at discrete points in
time when events occur. Continuous systems change continuously over time.
Deterministic refers to absence of randomness, not timing. Static systems do not
change over time.

,Question 4
TRUE or FALSE? Simulationbased methods can be used to solve engineering
design and analysis problems.
A) TRUE
B) FALSE
Answer: A
Rationale: Simulationbased methods are specifically designed to use simulation
models to solve engineering design and analysis problems. This is a core goal of
simulation courses like ISYE 6644.
Question 5
Which of the following is a disadvantage of simulation?
A) It can model complex systems
B) It provides visual animation
C) Simulation output is random and can lead to misinterpretation
D) It allows for "whatif" analysis
Answer: C
3
, Rationale: A key disadvantage of simulation is that it gives "random" output and
lots of misinterpretation of results is possible. The other options are advantages of
simulation.
Question 6
What is the Future Events List (FEL) in discreteevent simulation?
A) A list of all possible system states
B) A variable that represents the heart of discreteevent simulation
C) A database of historical simulation runs
D) A list of random numbers to be generated
Answer: B
Rationale: The Future Events List (FEL) is a variable that forms the heart of
discreteevent simulation. It contains scheduled events and their associated times,
and the simulation clock advances to the most imminent event.
Question 7
TRUE or FALSE? In discreteevent simulation, the simulation clock always equals
real time.
A) TRUE
B) FALSE
