METHOD AND SYSTEM FOR DESIGNING A COMPLEX SYSTEM

The present disclosure relates to multi-objective optimization of complex technical systems. A method of designing a Pareto-optimal layout of a system includes processing (110) input data relating to defining a layout space of layout parameters, a target space of target parameters, and constraints in the layout parameters and the target parameters, determining (120) one or more sets of layout parameter values, each set specifying a layout configuration of the system to be modeled, receiving (130) objective responses for the system having layout configurations specified by the one or more sets of layout parameter values, wherein each objective response corresponds to a target parameter value achieved by the system when having a layout configuration specified by one of the sets of layout parameter values, applying (150) multi-objective optimization with respect to the target parameters to determine one or more further sets of layout parameter values, receiving (130) objective responses for the system having layout configurations specified by the one or more further sets of layout parameter values, repeating the steps of applying multi-objective optimization and receiving respective objective responses until an abort criterion is met, and providing (160) a user interface for Pareto-optimal design of the system to be modeled, the user interface configured for selecting a specific layout configuration on basis of visualizing objective trade-offs inferred from the objective responses for the respective sets of layout parameter values, wherein the trade-offs are inferred from the objective responses based on determining Pareto-optimal points.
