6.3.2 Simulation-based Optimization using the 1-Min
Resolution Data
The data for the machine states in the 1-minute resolution is taken from the
machine controllers. The data records from the monitored machine state simulation in the production are assigned to the machine states. Before, the exported
files have been checked for completeness and correctness. Duplicates, empty or
incorrect data records were not found. The data records were imported into the
simulation model and linked to the corresponding machine states. The simulation
model time unit was set to “minutes”, as well as the timeout unit of the machine
state transitions. To be able to compare the achieved optimizations against reference values, one week of production 8 is simulated without using the optimization
parameters in the Reference Scenario. The reference scenario was then duplicated
to have exactly the same starting point and stored as Optimization Scenario. For
the optimization scenario, the total consumption optimizer experiment and the
peak consumption experiment were created and executed.
8 At this point, the week from May, 20th to 26th was chosen, as the energy data for this period
is available and the model can therefore be validated well.
