Lecture 2 Flashcards
What is the first step in the procedure of building a model?
Why is it important to clearly define the goals of a model?
- It ensures the model is focused on answering the correct questions.
- Helps in deciding the complexity and structure of the model (e.g., size structure for fish populations).
- Prevents unnecessary complexity or wrong model application.
What are the main steps in constructing a model?
- Problem definition
- Conceptualization of the model
- Mathematical formulation
- Verification
- Numerical formulation
- Sensitivity analysis
- Calibration
- Validation
