Model Development

The process of modelling consists of a number of layers; the following is a description of the modelling workflow:

  1. Definition of the problem
  2. Verification of information available
  3. Selection of model structure
  4. Establishing a simple model
  5. Sensitivity analysis
  6. Experimental tests of the model predictions
  7. Stating the agreements and divergences between experimental and modelling results, including any emergent behaviour
  8. Iterative refinement of model

The real world is dominated by complexity, especially biological systems
Mathematical modelling and computer simulations provide a means of understanding the innate funtioning of system - dynamics, and to arrive at well-founded predictions about their future development and the effect of interactions with the environment. So what is a model? A model is an abstract representation of objects and processes that explain the features/nature of these objects or processes. We present the model of our construct, as a system of differential equations to describe the dynamics of that network.
