The grey correlation analysis between technology readiness level and performance in civil aircraft

Advanced technology level is an important guarantee of civil aircraft projects, and it also must be adapted to market and consumers. This study mainly explores the technology dimension and its effect on performance in the design of civil aircraft. We develop four dimensions for aircraft technology readiness level, and conduct an empirical study among airports and airlines in China, build a grey correlation model of technology with aggregate data. The results indicate that that economy and comfort had the most important function on performance than general technology and provides a reference for civil aircraft marketing. Besides, the above grey correlation model can do well using data with poor unit data and an abnormal distribution.
