ISYE6644 (Simulation) Midterm 1
review Q&As (Verified Answers) 2026
What are some characteristics of simulation models? - correct answer
Discrete (vs. continuous)
✅ 1.
2. Stochastic (vs. deterministic)
3. Dynamic (vs. static)
What is simulation? - correct answer
process of system over time.
✅ Simulation is the imitation of a real-world
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
conceptual system behavior.
✅ 1. Describe / analyze real or
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
accomplish its goals?
✅ 1. Will the system
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
too complicated for analytical / numerical treatment
✅ 1. Can study models
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
so easy
✅ 1. Sometimes not
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.
answer ✅
D) Simulations are often tedious and time-consuming to produce. - correct
