      abstract     = {Heavy-duty vehicles waste a major part of their fuel energy
                      in the exhaust gas. To recover energy from the exhaust gas,
                      Organic Rankine Cycles are a promising technology. However,
                      both, the Organic Rankine Cycle and its working fluid have
                      to be tailored to the transient energy input by the exhaust
                      gas. For this purpose, we developed the so-called 1-stage
                      Continuous-Molecular Targeting - Computer-aided Molecular
                      Design (1-stage CoMT-CAMD) method. 1-stage CoMT-CAMD
                      integrates the design of novel working fluids as degree of
                      freedom into the process optimization. However, so far,
                      1-stage CoMT-CAMD is limited to a nominal operating point.
                      In this work, we enable the integrated design for transient
                      heat sources by combining 1-stage CoMT-CAMD with aggregation
                      techniques. Aggregation techniques allow us to represent the
                      many operating points due to the transient heat source by a
                      few aggregated operating points serving as input for the
                      integrated design. A subsequent assessment of the identified
                      working fluids ensures safety and environmental
                      friendliness. The resulting algorithm is applied to the
                      design of an Organic Rankine Cycle on heavy-duty vehicles
                      using the VECTO long haul cycle to characterize the
                      transient exhaust gas. For this case study, 6 aggregated
                      operating points are sufficient to represent the transient
                      exhaust gas accurately. The optimal identified working fluid
                      is ethyl formate and increases the net power output by
                      $30\%$ compared to the commonly used working fluid ethanol.},
