Q1 QUESTION 1 OF 221 ISYE 6644 Simulation Exam 1
True or False ? Discrete-event simulations are particularly suitable for analyzing
continuous-flow phenomena such as the velocity and altitude of an aircraft as it comes in
for a landing.
CORRECT ANSWER
False
RATIONALE
Discrete-event simulations model systems where changes occur at specific points in time,
making them unsuitable for continuous-flow phenomena like an aircraft's velocity and
altitude, which require real-time, continuous data representation to accurately capture
dynamics and transitions. Continuous systems demand different modeling approaches, such
as differential equations, to reflect the fluid nature of the variables involved.

Consider a single-server queue simulation with i.i.d. exponential interarrivals, i.i.d.
exponential services, and a first-in-first-out service discipline. Suppose that the arrival
rate is 5 per hour, and the service rate is 4 per hour. What will happen in the long run?
CORRECT ANSWER
b) The server will be busy all of the time.
RATIONALE
In a single-server queue with arrival and service rates of 5 and 4 per hour, respectively, the
system is unstable as the arrival rate exceeds the service rate, leading to an infinite queue
and ensuring the server remains continuously busy in the long run. This phenomenon
exemplifies the principles of queueing theory, specifically the behavior of M/M/1 queues
under high traffic intensity.
Q3 QUESTION 3 OF 221 ISYE 6644 Simulation Exam 1
If the covariance of X and Y is 1/2, then X and Y cannot be independent.
CORRECT ANSWER
True
RATIONALE
Covariance quantifies the degree to which two variables change together; a non-zero
covariance indicates a relationship, thus violating the condition for independence where the
covariance must equal zero. Therefore, a covariance of 1/2 confirms that X and Y are not
independent.

The planet Glubnor has 120-day years. Suppose there are four Glubnorians in the room.
What is the probability that at least two of them share the same birthday?
CORRECT ANSWER
0.049
RATIONALE
Calculating the probability that at least two Glubnorians share a birthday involves applying
the complement principle, where the probability of unique birthdays is computed first,
leading to a surprisingly low likelihood of shared birthdays due to the limited number of days
in their year. This scenario illustrates the birthday problem, highlighting how rapidly
probabilities converge with increasing sample sizes relative to available outcomes.
Q5 QUESTION 5 OF 221 ISYE 6644 Simulation Exam 1
Suppose the arrivals of clients to a bank can be modeled as a Poisson process with a given
hourly rate λλ . Then the number of clients arriving between 10:00-11:00 am is independent
of the number of clients arriving between 1:00-2:00 pm.
CORRECT ANSWER
True
RATIONALE
In a Poisson process, events occur independently over time, meaning the number of arrivals
in non-overlapping intervals, such as 10:00-11:00 am and 1:00-2:00 pm, does not influence
each other. This independence is a fundamental characteristic of Poisson distributions,
reinforcing the nature of random arrivals.
