This paper outlines a comprehensive, structured, and robust methodology for decision making in the early phases of aircraft design. The proposed approach is referred to as the Technology Identification, Evaluation, and Selection (TIES) method. The nine-step process provides the decision maker/designer with an ability to easily assess and trade-off the impact of various technologies in the absence of sophisticated, time-consuming mathematical formulations for project resource allocation. The method also provides a framework where technically feasible and economically viable alternatives can be identified with accuracy and speed while the impact on the economics is quantified. Furthermore, structured and systematic techniques are utilized to identify possible concepts and evaluation criteria by which comparisons could be made. Through the implementation of each step, the best family of alternatives for a customer-focused overall measure of value can be identified and assessed subjectively or objectively. This method was applied to a 150 passenger, intra-continental commercial transport as a proof of concept investigation.
