Layers of abstraction for describing production facilities

• Multilayered architecture
  • design pattern to cope with complexity
  • layer ≙ different aspect of the system
  • well-defined interaction between the layers
• Material flow layer
  • flow of the parts into and out of the facility
  • connects facility to a production line
  • provides logistic quantities, e.g. waiting time, utilization
• Process control layer
  • important for complicated manufacturing processes
  • models internal process logic
  • several manufacturing phases possibly with iteration
  • provides timing of the different phases
• Process physics layer
  • physical processes relevant in the different manufacturing phases
  • here: energy-related
  • provides e.g. timing of power requirements, total energy consumption
