Constraints
What is an example of a deterministic model?
Coin toss probability
Simple interest calculation
Weather prediction
Traffic flow simulation
What does a stochastic model incorporate that a deterministic model does not?
Relationships between variables
Assumptions
Randomness and probability
Mathematical calculations
Which element of a model represents the rules or conditions that must be met?
Variables
Constraints
Parameters
Relationships
What is the first step in the process of creating a model?
Defining the problem and objectives
Collecting data
Building the framework
Running simulations
Which of these is an example of a static model?
A real-time traffic simulator
A financial balance sheet
Weather forecasting model
Stock market simulation
What is sensitivity analysis used for in modeling?
To increase model complexity
To evaluate how changes in inputs affect outputs
To eliminate the need for assumptions
To simplify a model
Which of these is a dynamic model?
Income statement for a single month
Climate change simulation
A static organizational chart
A simple multiplication formula
What is the importance of defining assumptions in a model?
To make the model easy to understand
To provide a basis for predictions and analysis
To add unnecessary complexity
To avoid using variables
In modeling, what does the term 'validation' refer to?
Creating random outputs
Ensuring the model's results align with real-world data
Making the model overly complex
Running multiple simulations
What is an example of a relationship in a model?
Total cost = price × quantity
Fixed cost = constant value

Quantities that can be adjusted or vary
Assumptions made during the modeling process
Rules or conditions that must be met
