simulation (DES), the machine states and machine state changes can be exactly
reproduced. In combination with the time-continuous presentation of the energy
consumption behavior of the machines (SD), the hybrid simulation model becomes a combined one, linking the discrete-event and the continuous time advance
in one model.
The extraction and evaluation of the exact energy consumption profiles is complex and time-consuming. In addition, administrative regulations often prohibit
the collection and use of high-resolution data that could be used to determine
employee productivity. The reality in production companies often looks like that
energy data is selectively collected for single machines or production lines and
the use of this collected data is restricted. For this reason, the possible application
of the developed methodology for the case of unavailable energy consumption
load profiles is described below.
Figure 6.19 Required machine setup to use energy consumption profiles
To depict the energy consumption behavior of the machines, the reproduction
of the exact energy consumption behavior will be dispensed with and a representation of the energy consumption via calculated mean values is used instead.
This results in the utilization of one energy consumption value per machine state
