Exam 16: Simulation

An airline reservation system first asks customers whether they want to schedule a domestic or an international flight.Sixty-five percent of the reservations are for domestic flights.The time distribution of advance sales is also important,and it is given below. ​ a.Place the appropriate random number ranges in the tables above. b.Set up and perform a simulation for three customers.Determine whether they want a domestic or international flight,and how far in advance the reservation is being made.Use random numbers from this list: .632 .715 .998 .671 .744 .021

Which of the following statements is INCORRECT regarding the advantages of simulation?

A simulation model provides a convenient experimental laboratory for the real system.

Estimates of the financial information for a new product show the following information: ​ Use the random numbers .51,.97,.58,.22,and .16 to simulate five trials.What is the net profit for each trial?

On a visit to an amusement park you pass someone who has just ridden a roller coaster and asks you for directions to the First Aid Station.Realizing that traffic at the First Aid Station would be something to study with simulation,you gather some information.Two EMTs staff the station,and patients wait and go to the first one available.People coming there can be divided into two groups: those who need something minor (e.g.Tylenol,a band-aid)or those who need more help.Assume those in the first group constitute 25% of the patients and take 5 minutes to have their problem solved.Those in the second group need an uncertain amount of time,as given by a probability distribution.Develop a flowchart for this simulation problem.

Computer-generated random numbers are normally distributed.

In comparing different policies using simulation,one should use the same set of random numbers whenever possible.

​Explain the difference between verification and validation as they relate to a simulation model.

Values for the probabilistic inputs to a simulation

One disadvantage of simulation is that it is limited in the variety of probability distributions that can be used in modeling a system.

Common features of simulations--generating values from probability distributions,maintaining records,recording data and summarizing results--led to the development of

In a Monte Carlo simulation,each simulation trial is dependent upon the result of a previous trial.

​How can historical information be used to create discrete probability distributions?

​Simulation is to be used to study customer waiting patterns at several branches of an organization.Acknowledging that arrivals and service times follow different distributions over the branches,of what use is the development of a general simulation model?

Trials of a simulation show what would happen when values of the probabilistic input change.

A quantity that is difficult to measure with certainty is called a

When events occur at discrete points in time

Which of the following statements is INCORRECT regarding the disadvantages of simulation?

A simulation model uses the mathematical expressions and logical relationships of the

Susan Winslow has two alternative routes to travel from her home in Olport to her office in Lewisburg.She can travel on Freeway 5 to Freeway 57 or on Freeway 55 to Freeway 91.The time distributions are as follows: ​ Do a five-day simulation of each of the two combinations of routes using the random numbers below.Based on this simulation,which routes should Susan take if her objective is to minimize her total travel time?
