Validation

Answer 26

Make sure your mental model and thus the computer model runs as expected in reality

Why is model verification and validation important? To make sure that the computer model developed correctly mimics the behavior of the dynamic system modeled To gain confidence in that experimentation results can be trusted as accurate predictions of the reality To make sure that the model is correctly coded To make the simulation project lasts longer so you can charge the client more money

Question 28

Which of the following can be used as input to ProModel for activity times? Actual data A user created distribution Standard distributions Opinions from the workers

Answer 28

Actual data A user created distribution Standard distributions

Question 29

Under what circumstances would you use the actual data directly instead of a distribution for an activity time? When there is no standard distribution that can fit the data When you want to start with a simple rough-cut model When you need to use the output from one model to be the input of another model When you cannot create a user distribution for given data All of the above

Answer 29

When you need to use the output from one model to be the input of another model

Question 30

What are the disadvantages of using actual data instead of a distribution in ProModel?

All of the above

Question 31

Assume that a new system is being simulated and the only estimate available for a manual operation is a most likely value, how would you handle this situation?

use that value first for rough cut. Do sensitivity analysis.

Question 32

Triangular distribution

Question 34

Why would a normal distribution likely be a poor representation of an activity time? Because not all the processes are normalized Because the activity time may not follow the central limit theory Because the normal distribution is unbounded on both sides All of the above

Answer 34

Because the normal distribution is unbounded on both sides

Question 35

Since many theoretical distributions are unbounded on the bottom, what happens in ProModel if a negative value is sampled for an activity time? An error message will occur The negative value will be treated as a zero The negative value will be used and resulting a deduct of the activity time None of the above

The negative value will be treated as a zero
