22
Q

Which step takes the longest time in doing a simulation project?

Model Building

Data Collection and Analysis

Verification and Validation

Experimentation

A

Data Collection and Analysis

23
Q

Model Formulation

A

Create the conceptual framework of the system in question and develop sketch or layout drawing

24
Q

Model Development

A

Develop computer simulation models based on the mental model and data collection results

25
Q

Verification

A

Make sure that the model runs as expected in your mental model

26
Q

Validation

A

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

27
Q

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

A

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

28
Q

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

A

Actual data

A user created distribution

Standard distributions

29
Q

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

A

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

30
Q

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

Actual data may not be enough to support a long run

Actual data may not be enough to support multiple replications

Actual data may not cover all possible values that were not collected during the data collection

All of the above

A

All of the above

31
Q

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?

A

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

32
Q

Assume that you had historical data on truck arrivals for the past year, how would you arrive at an appropriate arrival distribution to model the system for the next six months?

A

analysis of data and try to forecast. Then fit to a distribution

33
Q

Assume that you have the minimum, maximum, and most likely time it takes for a physician to see a patient. What distribution will use to model the activity time here?

  Normal distribution 
  Uniform distribution 
  Exponential distribution 
  Triangular distribution 
  All of the above
A

Triangular distribution

34
Q

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

A

Because the normal distribution is unbounded on both sides

35
Q

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

A

The negative value will be treated as a zero
