based on different simulation paradigms. The production flow component includes
all setups and parameters that are linked to production planning and the production material flow to depict and parameterize the flow of entities through the
production machines. The machine component contains all relevant process parameters and the internal process logic of all production machines involved in the
manufacturing processes. While the inside of the machines is treated as black
box in the material flow model, it is specified in detail in the machine component
using the tools of the agent-based simulation, which is event-discrete regarding
the time advance. The ideal way to represent the behavior of machines is to treat
them as agents and map possible states and transitions with state-graphs. The
energy component is used to model the energy consumption behavior of the single production machines over time, requiring a continuous simulation technique
in form of System Dynamics.
All modules are designed in a flexible way to be used for both, analyzing
individual production lines or depicting entire production areas. For the modeling
of production processes, the adequate level of detail must be selected. On the one
hand, the model should not lose itself in detail and should only depict relevant
influencing factors. On the other hand, it must be precise enough to obtain a
realistic picture of the energy consumption behavior.
The single components of the methodology as well as their interactions are
described in detail in sections 5.3.1 to 5.3.4. To have a consistent visualization
and description of individual sub-parts of the simulation module, a description of
all module components shown in Figure 5.3 is done.
All modules receive a unique name, indicating their functionality. Important
process and information flows will be visualized in the modules as far as it adds
value to the model conception. Parameters and additional requirements that are
either prefilled or have to be typed in by the user will be defined per module.
To support a holistic understanding of functionalities, all interfaces with involved
inputs and outputs as well as occurring feedback loops will be specified for each
module.
5.3.1 Production Flow Component
The production flow component describes the process-oriented flow of parts
through machine components and machines and comprises relevant production
flow and production planning parameters.
The structure of the entity-based production flow model includes all main
electrical consumers that make a significant and immediate contribution to the
