Summary:

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
