Section 1: Simulation Fundamentals and History
Question 1
What is simulation?
A. The exact mathematical solution to a system of equations
B. The imitation of a real-world process or system over time
C. A numerical optimization technique
D. A data collection method
Correct Answer: B
Explanation: Simulation involves generating an artificial history to draw inferences
concerning the operating characteristics of the real system that is represented .
Question 2
What are the three methods to "solve" a model, from easiest to hardest?
A. Numerical, Analytical, Simulation
B. Analytical, Numerical, Simulation
C. Simulation, Numerical, Analytical
D. Simulation, Analytical, Numerical
Correct Answer: B
, Explanation: Analytical methods provide exact solutions using mathematical equations.
Numerical methods provide approximate solutions using iterative calculations. Simulation
methods are used when analytical or numerical methods are infeasible .
Question 3
What are some characteristics of simulation models?
A. Only discrete and deterministic
B. Only continuous and stochastic
C. Discrete (vs. continuous), Stochastic (vs. deterministic), Dynamic (vs. static)
D. Only static models
Correct Answer: C
Explanation: Simulation models can be discrete or continuous, stochastic or deterministic,
and dynamic or static .
Question 4
What was the first use of a computer simulation?
A. Stan Ulam and Johnny von Neumann in 1946 after World War II, simulating
thermonuclear chain reactions for the H bomb
B. Simulating manufacturing processes in the 1960s
C. Weather prediction in the 1950s
D. Financial portfolio optimization in the 1970s
Correct Answer: A
Explanation: Stan Ulam and Johnny von Neumann used simulation in 1946 in the context
of the development of the H bomb, simulating thermonuclear chain reactions .
Question 5
Who is William Gosset?
, A. He invented the t distribution that is used ubiquitously in statistics
B. He invented the s distribution
C. He developed SIMSCRIPT
D. He invented tea
Correct Answer: A
Explanation: William Gosset, writing under the pseudonym "Student," developed the t-
distribution while working at Guinness Brewery .
Question 6
Who was Harry Markowitz?
A. He developed SIMSCRIPT simulation language and won the Nobel Prize in
Economics for portfolio optimization
B. He invented the normal distribution
C. He developed the first digital computer
D. He invented the Arena simulation language
Correct Answer: A
Explanation: Harry Markowitz was one of the first to develop SIMSCRIPT, a general-
purpose simulation language, and won the 1990 Nobel Prize in Economics for his work on
portfolio optimization .
Question 7
What was the main development in the simulation field in the 1960s?
A. First computer simulation
B. Industrial applications (manufacturing, queueing models)
C. Development of AI
D. Quantum simulation
Correct Answer: B
, Explanation: The 1960s saw simulation applied extensively to industrial problems,
particularly manufacturing systems and queueing models .
Question 8
TRUE or FALSE? Has anyone closely related to the field of computer simulation ever won
a Nobel Prize?
A. True
B. False
Correct Answer: A
Explanation: Harry Markowitz won the 1990 Nobel Prize in Economics for his work in
portfolio optimization and is highly regarded in the simulation community for developing
SIMSCRIPT .
Question 9
