    time

  • Organised components, interconnected for purpose
  • Boundary / environment
  • Synergy / systemic properties
  • Feedback (positive / negative)

Exercise In groups
  • For either the UK Education system or a Gas
    Domestic central heating system
  • Identify
  • components
  • interconnections
  • Purpose
  • Where the boundary is
  • External influences in the Environment
  • Represent it on a diagram transfer it to a
    flipchart. You will explain this to the rest of
    the class.

13
Qualities of a model
  • Reduce complexity of reality
  • Constructed for purpose
  • Purpose/ assumptions explicit
  • Scope applicability known
  • Ideally predictive

14
Summary
  • Systems - What why
  • Models - What Why
  • Modelling systems

15
Directed Study
  • Read OOSAD booklet Ch 1 2 and complete
    Exercises 1.1-1.7 and 2.1-2.4
