  text: If high demands are placed on a technical system in terms of its reliability,
    it is typically designed to be modular and redundant. However, a modular design
    also offers the potential for optimised operation of the system, for example through
    a clever choice of operating point. This paper presents a holistic approach to
    optimise the selection of an operating point for modular, parallel and reconfigurable
    mechatronic systems. The existing challenges are identified using the practical
    example of a modular DC fast charging system for electric vehicles. Practical
    solutions for these challenges are also presented. In particular, the provision
    of data for operating point selection and optimised operating point selection
    will be discussed. Finally, a comparison is made with conventional operating point
    selection. This shows that our approach enables a higher efficiency of the charging
    system.

  text: Systems that place high demands on availability are typically modular in design.
    However, a modular design also offers potential for optimized operation under
    norma requirements. In this paper we present an approach to find optimal operating
    points from the characteristic fields of individual modules. Our approach consists
    of a two-step procedure. In the first stage, Pareto sets are calculated using
    the NSGA-II genetic algorithm. The second stage contains a heuristic that finds
    situationally optimal operating points using a defined operating strategy.
