      abstract     = {Increasingly volatile electricity prices make simultaneous
                      scheduling optimization for production processes and their
                      energy supply systems desirable. Simultaneous scheduling
                      needs to account for both process dynamics and binary
                      on/off-decisions in the energy system and thus leads to
                      challenging mixed-integer dynamic optimization problems. In
                      this contribution, we propose an efficient scheduling
                      formulation that consists of three parts: a linear
                      scale-bridging model for the closed-loop process output
                      dynamics, a data-driven model for the process energy demand,
                      and a mixed-integer linear model for the energy system.
                      Process dynamics are discretized by collocation yielding a
                      mixed-integer linear programming (MILP) formulation. We
                      apply the scheduling method to a single-product reactor,
                      with $5.6\%$ economic improvement compared to steady-state
                      operation, and a multi-product reactor, with $5.2\%$
                      improvement compared to sequential scheduling. While
                      capturing $85\%$ and $96\%$ of the improvement realized by a
                      nonlinear optimization, the MILP formulation achieves
                      optimization runtimes sufficiently fast for real-time
                      scheduling.},
