Increasing the efficiency and effectiveness of the decision making process could improve the efficiency and effectiveness of aircraft designers. The Decision Support Problem Technique, that is currently being developed and implemented at the University of Houston, is offered as a way in which this can be done. In this paper we provide an overview of the DSP Technique and its possible applications to aircraft design. A compromise DSP template has been developed for the conceptual design of subsonic transport aircraft which has six system variables, namely, wing span, wing area, fuselage diameter, fuselage length, take-off weight and installed thrust. System constraints include considerations of thrust, F.A.R. requirements, weight matching, range, wing loading, form factors for wing and fuselage, etc. These are represented algebraically using standard subsonic aircraft theory that is applicable to the design of medium to long range subsonic transport aircraft. Goals that model technical efficiency and economic efficiency are also included. The technical efficiency is modeled by a set of goals that include considerations pertinent to fuel weight, endurance, useful load fraction etc. Economic efficiency is modeled, at present, in terms of rate of return. This template, given a set of mission requirements, can be used to obtain a 'superior' aircraft configuration that satisfies a set of system constraints and best achieves the aspirations of the designer as quantified by the goals. The template has been tested and validated using the known mission requirements and design constants of the Boeing 727-200. For template validation, convergence of the system variables was tested using different initial designs to determine if the same final design could be achieved. The template results were found to be within 3 % of agreement to the actual aircraft configuration, and convergence of the system variables was verified.The template was then exercised to understand the effect of the relative importance of the economic and technical efficiencies on the configuration.
