Embodiment Construction

[0027] refer to Figure 1-2 . The specific steps of the civil aircraft cabin comfort quantitative evaluation method of the present invention are as follows:

[0028] Firstly, the questionnaire design of civil aircraft cabin comfort is carried out, and the reliability and validity analysis is carried out in the statistical analysis software SPSS. Questionnaires are distributed through the Internet or on-site surveys to collect passengers' opinions on the comfort of civil aircraft cabins. In order to ensure the reliability of the data, the number of samples is more than 200.

[0029] For the results of the questionnaire, factor analysis is carried out in the statistical analysis software SPSS, and a civil aircraft cabin comfort evaluation index system is summarized and constructed, including the target layer, criterion layer and index layer. Refer to the attached figure 2 , the civil aircraft cabin comfort evaluation index system is divided into three layers, the target layer...

Abstract

The invention discloses a civil aircraft passenger cabin comfort quantitative evaluation method which is used for solving the technical problem of poor accuracy of an evaluation result of an existing comfort evaluation method. The technical scheme is that key indexes are acquired from research data by adopting a factor analysis method; a three-layer civil aircraft passenger cabin comfort index system is established; a mutual influence relationship of all the indexes is analyzed by adopting a DEMATEL (Decision Making Trial and Evaluation Laboratory), and according to importance degrees, weights are allocated; passenger cabin comfort is evaluated by adopting a multistage fuzzy comprehensive evaluation method; and by utilizing a subordinate theory of fuzzy mathematics, subjective fuzzy evaluation of the comfort is converted into quantitative evaluation. Accuracy of the evaluation result is improved.

Description

technical field [0001] The invention belongs to the technical field of aerospace, and in particular relates to a method for quantitatively evaluating the cabin comfort of a civil aircraft. Background technique [0002] Comfort, safety, economy and environmental protection are the main criteria for the design and evaluation of current civil airliners. With the development of science and technology and the improvement of people's living standards, passengers' requirements for comfort when flying in an airplane continue to increase, and comfort has become an important factor in enhancing the competitiveness of airlines. The research on cabin comfort of civil aircraft has become a crucial part of the development of the current air transport industry. Understanding the evaluation method of civil aircraft cabin comfort can guide the civil aircraft cabin design process and provide designers with data support and design feedback, which is of great significance. [0003] The docume...
