ISYE 6644 2 FINAL TEST 2026 QUESTIONS
WITH CORRECT ANSWERS GRADED A+
◍ Validation.
Answer: The process of determining whether the simulation model is an
accurate representation of the real-world system being studied.
◍ Verification.
Answer: The process of ensuring that the simulation model is implemented
correctly and that the program runs as intended.
◍ The multivariate normal distribution's covariance matrix sigma can be
decomposed into the form sigma = CC^
T. What does the C informally stand for?.
Answer: Cholesky
◍ Seed.
Answer: The initial value used to start a pseudo-random number generator.
◍ TRUE or FALSE? In Arena, you can assign different customers completely
different sequences of visitation stations?.
Answer: True
◍ Simulation Languages.
Answer: Specialized software packages designed to facilitate the building
and running of simulation models (e.g., Arena).
◍ Simulation Methods.
Answer: Techniques that involve imitating the operation of a system over
time to study its behavior and draw inferences.
◍ What does "LCG" mean?.
Answer: Linear Congruential Generator
,◍ TRUE or FALSE? For easy display and organizational purposes, our Call
Center simulation is divided into several submodels..
Answer: True
◍ TRUE or FALSE? In Arena, the Schedule spreadsheet can be used to
establish either resource capacity schedules or arrival rate schedules..
Answer: True
◍ Simulation Model.
Answer: A high-level representation used to imitate the operation of a
real-world process or system over time.
◍ YES or NO? Is it ever OK to use the midsquare random number generator?.
Answer: No
◍ Stochastic Model.
Answer: A model that incorporates randomness or probability into its
operation.
◍ Dynamic Model.
Answer: A model that evolves or changes over time.
◍ Which of the following statements about the RANDU generator is true?.
Answer: Something just ain't right about that boy, the generator is given by
Xi = 65539Xi-1mod(2^31), the PRNs appear at first glance to be uniform,
but funny things happen when you look at the plots of the PRNs in multiple
dimensions, the PRNs are distributed on just 15 hyperplanes.
◍ Discrete Model.
Answer: A model where the state of the system changes only at a countable
number of points in time.
◍ TRUE or FALSE? In Arena, you can pre-assign a service time as an
attribute before you actually get to the server that you'll be using..
Answer: True
◍ Batch Means.
Answer: A method for analyzing steady-state simulations by dividing a
, single long simulation run into contiguous batches and treating the mean of
each batch as an independent observation.
◍ If the chi-squared goodness-of-fit statistic is much greater than the relevant
quantile, what do we do?.
Answer: Reject the goodness-of-fit test and declare that the PRNs are
probably not uniform.
◍ TRUE or FALSE? Crazy stuff can happen if you start fooling around with
multiple server visits, service priorities, and server times..
Answer: True
◍ TRUE or FALSE? (1XOR1)XOR1 = 1?.
Answer: True. (1XOR1)XOR1 = 0XOR1 = 1
◍ Queueing Models.
Answer: Simulation models used to analyze systems involving waiting lines,
such as call centers or manufacturing processes.
◍ Inverse Transform Method.
Answer: A technique for generating random variates from a specific
distribution by using the inverse of its cumulative distribution function
applied to a Unif(0,1) random number.
◍ TRUE or FALSE? In the process-interaction worldview, at any time the
system may have many entities interacting with each other as they compete
for resources?.
Answer: True
◍ TRUE or FALSE? RANDU is a pretty good generator..
Answer: False. RANDU has several problems with hyperplanes.
◍ Variance Reduction Techniques.
Answer: Methods used to improve the efficiency of a simulation by reducing
the variability of the output statistics.
◍ Which of the following are true?.
Answer: The closer the majorizing function t(x) is to the true p.d.f. f(x), the
