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
