Abstract:
In today's aircraft design, more and more attention is paid to the conceptual and preliminary design stages in order to increase the capability of choosing a design that will be successful. Therefore, the decisions made during these design phases play a central role in determining the success of a design. Decision-making techniques at these stages, must manage multiple, conflicting criteria and capture associated uncertainties. The method presented in this study was developed from Joint Probability Decision Making (JPDM), a probabilistic multiple criteria decision-making technique. The proposed method eliminated the limitations that JPDM has by utilizing Utility Functions to represent the decision-maker's preference. An advanced rotorcraft concept selection problem is performed in order to demonstrate the improvements, and the results obtained from the proposed method and the JPDM technique are compared with each other.
