Energy-sensitive process chain optimization on the example of forging

We present a mathematical optimization model for the determination of an energyminimal process chain, given a metro map describing the single process chain variants and a description of the processes themselves. This approach is applied to a small process chain example that includes a forging process. For some of the processes several parameter settings can be used. That leads to process variants in the optimization model that differ in the required input temperatures. After the calculation of the optimal process chain for the considered example we extend our mathematical model in such a way that uncertainties concerning the values of the energy demands can be taken into account.
