Abstract:
Modelling is the process by which we obtain a model by observing the behaviour of the system it is to represent
A good modeller takes into consideration:
- How it should be used
- What it’s able and unable to do
- How accurate is it, compared to the real system
- What the cost of applying the model will be
Two Ways Of Modelling:
Top Down:
- Start with detailed description of elements
- Large set of equations of general applicability
Bottom Up:
- Start from statement of modelling objectives for the intended application
- Smaller set of equations for specific situation
