1|with 34 Actual Questions and Correct
Answers Graded A+
What is simulation (M1L3)? -CORRECTANSWER Imitation of a real-world process or
system over time.
What is a model (M1L3)? -CORRECTANSWER High-level representations of the
operation of a real-word process or system.
Is the following a discrete or continuous model:
1 customer shows up and waits in line, and then another, and so on (M1L3). -
CORRECTANSWER Discrete model
Is the following a discrete or continuous model:
An hourly weather prediction for precipitation over time (M1L3). -CORRECTANSWER
Continuous model
Is the following a stochastic or deterministic model:
Calls that randomly arrive at a call center (M1L3). -CORRECTANSWER Stochastic
model
Is the following a stochastic or deterministic model:
, Predicting the voltage if we know the current and resistance in a circuit (M1L3). -
CORRECTANSWER Deterministic model
What does it mean for a model to be dynamic vs. static (M1L3)? -CORRECTANSWER
Dynamic models have changing relationships between variables over time. In static
models, the relationships between variables are fixed (e.g., V = IR).
What are the three methods to "solve" a model: from easiest to hardest (M1L3)? -
CORRECTANSWER 1. Analytical (exact)
2. Numerical methods (approximate)
3. Simulation methods (approx. with randomness)
In the 1940s, who used early computers to simulate thermonuclear chain reactions as
part of the Manhattan project (also had a role in the foundations of Monte Carlo
methods)(M1L4).
a) William Gossett, aka - "Student"
b) Harry Markowitz
c) Comte de Buffon
d) Ulam, Metropolis, and von Neumann
e) Justin Bieber -CORRECTANSWER ---d) correct CORRECTANSWER---
a) Student's t-test, analytical techniques for Guinness Beer.
b) Nobel in Econ for optimiz. of financial portfolios, invented Sim Script language.
