QUESTIONS AND 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.
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 answer-✅A) He invented the t distribution that is used ubiquitously in
statistics.
What was the first use of a computer simulation? - correct answer-✅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 answer-✅Industrial
applications
-manufacturing
-queueing models
Who was Harry Markowitz? - correct answer-✅He was one of the first guys to develop a language called
SIMSCRIPT. He also won a nobel prize for some of the work he did in optimizing financial portfolios
(portfolio theory).
In terms of simulations origins in manufacturing, what are some of the ways that simulation was/is
used? - correct answer-✅1. Calculated the movement of parts and interaction of system components.
2. Evaluates part flow thru the system
3. Examines conflicting demand for resources
4. Studies contemplated changes before their introduction
5. Prevent design blunders
YES or NO? Has anyone closely related to the field of computer simulation ever won a Nobel Prize? -
correct answer-✅Yes - Harry Markowitz won the 1990 Nobel Prize in Economics for his work in the field
of portfolio optimization. He is highly regarded in the simulation community for his conception and
development of the general-purpose simulation language SIMSCRIPT.
Who is Dr. Harold Shipman? - correct answer-✅He killed his patients using heroin overdoses
Caught after carelessly revising a patient's will, leaving all her assets to himself
