      abstract     = {The synthesis of energy systems is a two-stage optimization
                      problem where design decisions have to be implemented
                      here-and-now (first stage), while for the operation of
                      installed components, we can wait-and-see (second stage). To
                      identify a sustainable design, we need to account for both
                      economical and environmental criteria leading to
                      multi-objective optimization problems. However,
                      multi-objective optimization leads not to one optimal design
                      but to multiple Pareto-efficient design options in general.
                      Thus, the decision maker usually has to decide manually
                      which design should finally be implemented. In this paper,
                      we propose the flexible here-and-now decision (flex-hand)
                      approach for automatic identification of one single design
                      for multi-objective optimization. The approach minimizes the
                      distance of the Pareto front based on one fixed design to
                      the Pareto front allowing multiple designs. Uncertainty
                      regarding parameters of future operations can be easily
                      included through a robust extension of the flex-hand
                      approach. Results of a real-world case study show that the
                      obtained design is highly flexible to adapt operation to the
                      considered objective functions. Thus, the design provides an
                      energy system with the ability to adapt to a changing focus
                      in decision criteria, e. g., due to changing political
                      aims.},
