ISYE6644 (SIMULATION) MIDTERM 1
NEWEST 2025 QUESTIONS AND
DETAILED CORRECT ANSWERS | A+
GRADE VERIFIED ANSWERS
What are some characteristics of simulation models?
Correct Answer 1. Discrete (vs. continuous)
2. Stochastic (vs. deterministic)
3. Dynamic (vs. static)
What is simulation? Correct Answer Simulation is the
imitation of a real-world process of system over time.
Simulation involves the generation of an artificial history to
draw inferences concerning the operating characteristics
of the real system that is represented.
What is simulation good for? Correct Answer 1. Describe /
analyze real or conceptual system behavior.
2. Ask "what if" questions.
3. Aid in system design and optimization
4. Can simulate almost anything
What are the reasons to simulate? Correct Answer 1. Will
the system accomplish its goals?
2. Current system won't accomplish its goals, now what?
3. Need incremental improvement.
4. Create a specification or action plan
5. Solve a problem, like a bottleneck.
,6. Resolve disputes
7. Sell an idea
What are the advantages of simulation? Correct Answer 1.
Can study models too complicated for analytical /
numerical treatment
2. Study detailed relations that might be lost in the
analytical or numerical treatment
3. Use as a basis for experimental studies of systems
4. Use to check results and give credibility to conclusions
obtained by other methods.
5. Reduce design blunders
6. Really nice demo method
7. (sometimes) very easy
What are the disadvantages of simulation? Correct
Answer 1. Sometimes not so easy
2. Sometimes very time consuming / costly
3. Simulations give "random" output (and lots of
misinterpretation of results is possible)
4. To do a certain problem, better methods than simulation
may exist
We are interested in modeling the arrival and service
process at the local McBurger Queen burger joint.
Customers come in every once in a while, stand in line,
eventually get served, and off they go. Generally
speaking, what kind of model are we talking about here?
(More than one answer below may be right.)
A) Discrete
, B) Continuous
C) Stochastic
D) Deterministic Correct Answer (a) (because events such
as arrivals and service completions only happen once in a
while, as opposed to continuously); and (c) (because
customer arrival times, service times, shift changes, etc.,
are all random).
Which of the following can be regarded as advantages of
simulation? (More than one answer below may be right.)
A) Simulation enables you to study models too
complicated for analytical or numerical treatment.
B) Simulations can serve as very pretty demos that even
University of Georgia graduates can understand.
C) Simulation can be used to study detailed relations that
might be lost in an analytical or numerical treatment.
D) Simulations are often tedious and time-consuming to
produce. Correct Answer A) Simulation enables you to
study models too complicated for analytical or numerical
treatment.
B) Simulations can serve as very pretty demos that even
University of Georgia graduates can understand.
C) Simulation can be used to study detailed relations that
might be lost in an analytical or numerical treatment.
Who is William Gosset?
A) He invented the t distribution that is used ubiquitously in
statistics.
