6 Experimental Validation of the Methodology
which is used as the energy value over the entire duration of the state. The realization in the simulation model requires the definition of a parameter in the machine
logic and thus eliminates the complex representation of the power consumption
via table functions. The Bosch simulation model requires one table function per
machine state (Figure 6.19), summing up to 50 table functions in total.
While the number of data records used for the 1-minute resolution remains
manageable, the total number of datasets for the energy consumption per second
sums up to over 35.000 data records that have to be accessed in a one-secondfrequency during the simulation runs. The replacement of these amounts of data
with a total of 50 mean values reduces the access time and at the end the simulation and experimentation runtimes. The mean values are inserted in the setup of
the single machine logics (Figure 6.20).
Figure 6.20 Required machine setup to use calculated mean values
The calculation of the mean values for the Bosch machines was done using the
1-minute-resolution data for the comparison of the simulation run and the optimization experiment results to the Bosch optimization scenario (1-min resolution).
The decision for the 1-min resolution data is based on the fact that the energy
consumption data was recorded by the machine controllers and not by external
measuring equipment. Additionally, the resolution comparison showed that the
