Abstract: Touch control technology will be extensively applied in civil aircraft cockpits in the future; however, no ergonomic evaluation system and evaluation method for the display touch system of civil aircraft cockpits exist currently. Aiming at this problem, we first sort out the current standards and norms related to the touch control system of civil aircraft cockpit displays, and propose the man-machine ergonomic evaluation index system of civil aircraft cockpit display touch control systems in combination with the human factor investigation items in airworthiness regulations. Secondly, considering the fuzziness and grayness of the evaluation indexes, we improve the traditional fuzzy hierarchy comprehensive evaluation algorithm from two directions of data aggregation processing and index weight determination based on the gray correlation analysis. The expert reliability coefficient modified rank matrix is constructed to realize the quantitative description of expert cognitive characteristics, and the man-machine ergonomic comprehensive evaluation model of civil aircraft cockpit display touch control systems is established. Finally, combined with the ergonomic evaluation test cases of civil aircraft cockpit displays and touch systems under the project ACROSS, the influence of the configuration strategy of cockpit displays and touch systems on the ergonomic efficiency of the system is analyzed, and the applicability and rationality of the evaluation system and evaluation method are verified.
