ISYE6644 (SIMULATION) MIDTERM 1
QUESTIONS AND ANSWERS 2025
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

Who is William Gosset?
A) He invented the t distribution that is used ubiquitously in statistics.
B) He invented the s distribution that is used ubiquitously in statistics.
C) He invented tea.
D) He invented the word "ubiquitous".
