Creation of a Decision-Support Methodology for Selecting More-Electric Aircraft Subsystem Technologies

摘要

Ambitious aircraft emission goals combined with airline fuel costs are driving an increasing focus on energy efficiency for the aircraft industry. Aircraft Equipment Systems (AES) perform key aircraft functions, such as pressurization or control surface actuation, but they are also energy consumers. Selecting the AES technologies of the future is inherently a multi-criteria problem if all stakeholders are to be satisfied. The problem is further complicated because technologies cannot be considered to be completely independent and must be considered from a subsystem architecture perspective. This paper proposes an evolution of the Strategic Prioritization and Planning (SP2) method including a two-level approach that considers both independent technologies and integrated architectures. These are then linked to technology attributes and high-level objectives through qualitative subject matter expert driven relationships. The information is finally displayed in an interactive environment that ranks technologies and architectures, while also allowing the decision maker to define and explore the scenarios driving the rankings.
