Question 1

In modeling a simulation, random numbers from 00 to 99 are assigned with the intervals determined from frequency distributions for each behavior occurrence.Assume there are two behaviors, A and B, out of 50 tallies.On behavior A you record 15 tallies, and on behavior B you record 35 tallies.Which of the following is a correct random-number interval for behavior A (Choose the most appropriate answer)?
A)00 to 29
B)00 to 14
C)70 to 99
D)35 to 49
E)A or C

Question 2

A small vendor has either a good day of sales with an average of $1,000 or a bad day with an average of only $500 for the day.To simulate these outcomes, random numbers from 00 to 99 should be assigned with the intervals determined from the frequency distribution.If, during the last 100 days, the vendor had 27 good days and 73 bad days, which of the following is a correct random-number interval for a bad day?
A)28 to 99
B)27 to 73
C)27 to 100
D)27 to 99
E)00 to 26

Accepted Answer

The interval for a bad day should cover 73 out of 100 possible outcomes. Therefore, the interval should start at 27 and end at 99 (which includes 73 possible outcomes). Option D correctly reflects this interval.

A)00 to 19
B)01 to 20
C)00 to 39

Question 5

Which of the following is an example of general-purpose simulation software?
A)PC-MODEL
B)MAP/1
C)SIMFACTORY
D)Canella IV
E)OPUS/2.3

Accepted Answer

PC-MODEL is a general-purpose simulation software that allows users to build, simulate, and analyze complex models in various fields such as logistics, engineering, and finance. MAP/1, SIMFACTORY, Canella IV, and OPUS/2.3 are all examples of simulation software, but they are not typically classified as "general-purpose."

Question 6

Customers arrive at a single self-serve coffee machine in a busy mall at the rate of 20 per hour, following Poisson distribution.Each customer takes exactly 90 seconds to get his or her coffee.What is the expected number of customers in queue at this coffee machine?
A)1.0
B)1.5
C)0.5
D)2.0
E)3.0

Question 7

Which of the following is an example of general-purpose simulation software?
A)Link Trainer Programs
B)SIMSCRIPT II.5
C)SIM-Central
D)C++
E)Visual Basic

Accepted Answer

SIMSCRIPT II.5 is an example of general-purpose simulation software. A, C, D, and E are all programming languages, but not specifically designed for simulation.

Question 8

Assuming a 24 hour operation in a warehouse, and an arrival following Poisson distribution with mean rate of 36 per day and service (unloading using a single bay) following exponential distribution with a rate of 48 trucks per day, answer the following question.What is the expected waiting time in the system (in hours) for a typical truck?
A)2 hours
B)1 hour
C)1.5 hour
D)0.25 hour
E)0.5 hours

Accepted Answer

The expected waiting time in the system is given by Little's Law: W = L/λ, where W is the expected waiting time, L is the expected number of trucks in the system, and λ is the arrival rate. In this case, the arrival rate is 36 trucks per day, and the service rate is 48 trucks per day. The expected number of trucks in the system is L = λ/(μ-λ) = 36/(48-36) = 1.5 trucks. Therefore, the expected waiting time is W = L/λ = 1.5/36 = 0.042 hours, or approximately 2.5 minutes.

Question 9

Which of the following is not an example of general-purpose simulation software?
A)SIMAN
B)GPSS/PC
C)RESQ
D)GAPE/H
E)SLAMII

Accepted Answer

GPSS/PC, SIMAN, RESQ, and SLAMII are all examples of general-purpose simulation software. GAPE/H is not a real simulation software and therefore is not a valid example of general-purpose simulation software.

Question 10

Customers arrive at a common queue at the coffee station with two identical coffee machines in a busy mall at the rate of 48 per hour, following Poisson distribution.Each customer mixes his or her specialty coffee taking 2 minutes on an average following an exponential process.What is the expected number of customers in the system at this coffee station?
A)infinity
B)2.844
C)2.444
D)4.444
E)3
