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
