ISYE6644 (SIMULATION) MIDTERM 1 || ERRORLESS
SOLUTIONS 100%.
What are some characteristics of simulation models? correct answers 1. Discrete (vs. continuous)
2. Stochastic (vs. deterministic)
3. Dynamic (vs. static)
What is simulation? correct answers 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 answers 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 answers 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 answers 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 answers 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 answers (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 answers 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.
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. correct answers A) He invented the t distribution that is used
ubiquitously in statistics.
What was the first use of a computer simulation? correct answers Stan 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? correct answers Industrial
applications
