The need of future innovative, sustainable and circular aircraft configuration poses the necessity to extend the branches of the aeronautical research to the entire aircraft life-cycle, from the production, to the waste disposal after the end of the system operative life. This surely enlarge the design space making the decision-making process even more complex, having to consider multiple criteria at the same time while taking decisions. However, making decisions on future design configurations, exploring all the possible solutions on the design space, is essential to drastically reduce the overall aircraft cost. Usually, value-model theories are used to simplify the multi-criteria decision-making process. In this paper, the value model theory is leveraged for the identification of the best solution based on multiple criteria related to the aircraft, manufacturing and supply chain design. In addition, uncertainty propagation analyses are performed for the identification of the robust and flexible solutions, thus the solutions minimizing the value and being optimal independently from the strategic case analyzed. An aeronautical application case is presented to highlight the advantages of this study.
