Objective To investigate theoretically the method for evaluation of the cockpit display and control system. Methods Results A set of indexes for performance evaluation of aircraft cockpit display and control system is established based on a comprehensive analysis of determining factors, and the method of evaluation is put forward. Both subjective and objective evaluations of based on the carrying out mission are included. Subjective evaluation is quantified and weight coefficients of indexes are calculated by the analytic hierarchy process. The multi-level fuzzy evaluation is used in this system. Approch of the evaluation is as follows: Firstly,indexes for evaluation and test items are worked out based on analysis of situation of using the evaluation target. Secondly, in accordance with the selected indexes, weight coefficients of indexes are calculated by the analytic hierarchy process.Next,evaluation is completed by Cooper-Harper method and effectiveness evaluation of mission reached. Then the synthetical score from the subjective score and objective score for each index is calculated by given method. Finally, sort order is reached based on score by the minimax distance method general structure and realizing scheme of it are discussed. Conclusion Theoretically speaking, this method of evaluation is comprehensive and exercisable.It should be further verified practically.
