Systems!

System is a word used to define a set of components which interact and function between them. One of the main characteristics of a system is that it acts in a predictable way and is composed by:
  • Inputs
  • Outputs
  • Flows
  • Storages
  • Sources
  • Sinks
Systems can be classified into 3 different categories:
  • Open System: Materials and Energy are exchanged across the boundaries of the system.
  • Closed System: Energy is exchanged across the boundaries but matter is not
  • Isolated System: Neither matter nor energy is exchanged.
