To systematically evaluate and optimize the development roadmap of noise−reduction technologies for civil aircraft, a comprehensive assessment framework integrating the analytic hierarchy process (AHP) and quality function deployment (QFD) is established. Starting from representative aircraft noise sources, a technology list consisting of 23 noise−reduction approaches is compiled. Seven key evaluation criteria, including airworthiness compliance, total noise−reduction potential, and technology readiness level, are defined, and the corresponding weights are determined through AHP with consistency verification. Based on these weights, three QFD−based scoring methods are applied to compare the influence of individual judgment matrices and an aggregated judgment matrix on the final technology ranking. The results indicate that, provided all expert judgment matrices satisfy the consistency requirement, both the overall scores and rankings of the technologies remain stable across the three scoring methods. According to the results of Scoring Method I, hierarchical development lists and priority development lists of noise−reduction technologies are formulated. Among these technologies, nacelle acoustic liners and low−noise aerodynamic design of high−lift devices are recommended as priority development directions. This study provides a quantitative decision−making basis for the strategic planning and prioritization of noise−reduction technologies for civil aircraft.
