Cover Story: Selecting the final system design among Pareto optimal solutions is a challenging task. To support this choice, a decision-making tool for bi-objective optimization of an ORC power plant is developed and applied in this study. By indicating and excluding adverse design solutions, the choice of final operating conditions for the ORC is facilitated. View this paper.
