Q1 QUESTION 1 OF 151
What is the main reason simulation is useful for complicated supply-chain models?
Page 1
, ANSWER
Simulation can imitate complex systems with random demand, lead times, queues, inventory
rules, transportation delays, and shared resources when closed-form analysis is impractical.
Q2 QUESTION 2 OF 151
True or False: Simulation can be used to analyze supply-chain models too complicated to
solve analytically.
ANSWER
True.
Q3 QUESTION 3 OF 151
In discrete-event simulation, what is the Future Events List (FEL)?
ANSWER
The internal calendar/list of scheduled future events.
Q4 QUESTION 4 OF 151
True or False: Most discrete-event simulations have a Future Events List deep down.
ANSWER
True.
Q5 QUESTION 5 OF 151
Can an arrival event insert, delete, or reorder events in the FEL?
ANSWER
Yes; an event can schedule new events, cancel future events, and affect ordering.

, Q6 QUESTION 6 OF 151
How does next-event time advance work in discrete-event simulation?
ANSWER
The simulation clock jumps from one scheduled event time to the next.
Q7 QUESTION 7 OF 151
True or False: Nothing significant happens between consecutive events in most DES models.
ANSWER
True.
Q8 QUESTION 8 OF 151
What may still change between events in a DES?
ANSWER
Elapsed-time statistics can accumulate, but state changes occur at events.
Q9 QUESTION 9 OF 151
For bisection, what equation form do you need first?
ANSWER
Move everything to one side and define g(x)=0.
Q10 QUESTION 10 OF 151
For e^x = x^2, what g(x) should you use for bisection?
Page 3
, ANSWER
g(x)=e^x - x^2.
Q11 QUESTION 11 OF 151
What does a sign change between g(a) and g(b) tell you in bisection?
ANSWER
A root lies somewhere in [a,b], assuming g is continuous.
Q12 QUESTION 12 OF 151
In bisection, after checking the midpoint, which interval do you keep?
ANSWER
Keep the subinterval where g(x) changes sign.
Q13 QUESTION 13 OF 151
What is Newton's method update formula?
ANSWER
x_{n+1}=x_n - g(x_n)/g'(x_n).
Q14 QUESTION 14 OF 151
What is an Arena Decide module used for?
ANSWER
Branching/decision logic.
