      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 does not lead 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.},
