ISYE6644 (SIMULATION) MIDTERM 1
QUESTIONS & ANSWERS(RATED
A+)
What are some characteristics of simulation models? - ANSWER1. Discrete (vs.
continuous)
2. Stochastic (vs. deterministic)
3. Dynamic (vs. static)
What is simulation good for? - ANSWER1. 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? - ANSWER1. 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 is simulation? - ANSWERSimulation 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 are the advantages of simulation? - ANSWER1. 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? - ANSWER1. 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 - 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. - ANSWERA)

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".
E) He is the brother of Louis Gossett Jr., best known for his fine acting in many films,
including An Officer and a Gentleman. - ANSWERA) He invented the t distribution
that is used ubiquitously in statistics.
What was the first use of a computer simulation? - ANSWERStan Ulam and Johnny
von Neumann in 1946 after world war 2. They used simulation in the context of the
development of the H bomb.
The simulated thermonuclear reactions actually, chain reactions.
What was the main development in the simulation field in the 1960s? -
ANSWERIndustrial applications
-manufacturing
