  3. System, Models & Simulation Introduction • System - A system exists and operates in time and space. • Model - A model is a simplified representation of a system at some particular point in time or space intended to promote understanding of the real system.

  4. Simulation - A simulation is the manipulation of a model in such a way that it operates on time and space to control it, thus enabling one to review the interactions that might not otherwise be apparent because of their separation in time or space. A Simulation generally refers to a computerized version of the model which is run over time to study the and forecast interactions.

  5. A system is understood to be an entity which maintains its existence through the interaction of its parts. A modelis a simplified representation of the actual system intended to promote understanding. Whether a model is a good model or not depends on the extent to which it promotes understanding. Since all models are simplifications of reality there is always a trade-off as to what level of detail is included in the model. If too little detail is included in the model one runs the risk of missing relevant interactions and the resultant model does not promote understanding. If too much detail is included in the model the model may become overly complicated and actually preclude the development of understanding.
