Arrivals
To build arrivals, which cells have to be filled?

What is the difference between locations and resources in ProModel?
Locations do not move and resources can move in the model.
What happens when you build an entity without specifying its icon?
You will not see anything moving in the animation when you simulate it.

Computer Simulation
Please put the steps that one should follow in doing a simulation project in the right sequence.
- Gaining Organizational Support
- Problem Definition
- Statement of Objectives
- Project Planning
- Model Formulation
- Data Collection
- Model Development
- Verification
- Validation
- Experimentation and Optimization
- Results and Analysis and Presentation
- Implementation
Which step takes the longest time in doing a simulation project?
Model Building
Data Collection and Analysis
Verification and Validation
Experimentation
Data Collection and Analysis
Model Formulation
Create the conceptual framework of the system in question and develop sketch or layout drawing
Model Development
Develop computer simulation models based on the mental model and data collection results
Verification
Make sure that the model runs as expected in your mental model
Validation
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
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
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
Actual data
A user created distribution
Standard distributions
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
When you need to use the output from one model to be the input of another model
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
All of the above
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.
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?
analysis of data and try to forecast. Then fit to a distribution
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
Triangular distribution
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
Because the normal distribution is unbounded on both sides
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
