Exam 26: Simulation

Simulation is basically an optimizing technique.

The second step in the simulation process is to:

Monte Carlo simulations are deterministic.

An analyst wants to simulate observations from a Normal distribution that has a mean of 41 and a standard deviation of 3.The analyst draws a random number from a normally distributed table of random numbers.The random number is -2.00.The simulated value is:

A production operation consists of two steps.The time for the first step is uniformly distributed between 10 minutes and 20 minutes.The time for the second operation is uniformly distributed between 15 and 20 minutes.Process one cannot start a new unit until its previous unit has been passed to process two.Process two cannot accept another unit while still processing the previous one.Using these two random number strings (left to right),simulate the total time for three units: 11eab92b_c473_14f5_99e6_9f8cdf0be61a

When simulating numbers for an Exponential distribution,a table of random numbers can be used.

A Normal distribution has a mean of 9 and a standard deviation of 2.The random number + 1.00 has been drawn from a table of normally distributed random numbers.The simulated number is 10.

On cold mornings,the probability that David's car won't start is .22.When it doesn't start,he takes the bus and is late for work.When it does start,he drives to work on the freeway.Sixty-five percent of the time the freeway is clear,and he gets to work on time.The rest of the time he is late.Simulate 10 consecutive days' worth of trips to work using the random numbers given.Use the lower numbers in each string to represent "car won't start" and "freeway clear". 11eab92b_c472_9fba_99e6_93e1f503a652

Random numbers used in Monte Carlo simulation are generated by computer or from random number tables.

A Uniform distribution has endpoints of 250 and 400.Simulate three values of this distribution using these random numbers: 11eab92b_c473_14f4_99e6_91b1e89bbe2e

Dofasco managers used the Arena simulation model to determine if relatively small expenditures would result in productiv?ity improvements,

A Monte Carlo simulation implies that randomness has been incorporated in the simulation.

What term is used when seeking the best alternative for decision variables based on some measure of performance?

Simulation is used to determine the optimal solution to a problem.

In the sets of random numbers,every possible combination of the numbers has the same probability of appearing,and there are no discernible patterns.

A simulation model is validated if it adequately depicts real system performance.

The number of machine breakdowns per day in a large factory can be described by a Poisson distribution with a mean of 2.0.Simulate the number of breakdowns over a five-day period,using these random numbers: 11eab92b_c472_eddf_99e6_ad3905d06028

Monte Carlo simulation is only applicable to situations that have elements that can be described by random variables.

A Uniform distribution has end points of 40 and 90.A random number of 20 from a two-digit random number table equates to a simulated value of 50.

The random numbers used in Monte Carlo simulations come from:
