摘要： 针对民机客舱舒适性现有评价方法中缺乏数学定量评价的问题，提出了基于主客观
综合赋权的民机客舱舒适性定量评价方法。首先在相关乘客调研基础上，建立了较全面的民机客
舱舒适性评价指标体系。提出一种将主观决策实验室分析方法与客观熵权法相结合的综合权重赋
值方法，既能有效避免赋权过程中人为主观因素的过度影响，又能充分挖掘调研数据中的真实信
息，提高了各级评价指标权重数据的客观性和准确性。最后，针对民机客舱舒适性评价中的模糊
性、主观性，利用模糊数学把舒适性主观评价转化为定量评价，得到了较客观的评价结果。通过
实例验证，该结果可以对设计进行反馈，指导设计调整过程，是一种有效的舒适性评价方法。

Abstract: Aiming at the current problem lacking of quantitative comfort evaluation method, a
multistage fuzzy comprehensive evaluation method based on DEMATEL-entropy is proposed to
quantify the comfort evaluation in civil aircraft cabin. At first, on the base of relevant passenger
comfort survey, a multistage evaluation indicator system is built. And then a comprehensive weight
assigning method is proposed, which combined the subjective method-DEMATEL with the objective
one-entropy method. It could reflect and quantify the importance of indicators by analyzing the inner
casual relationship between them. The comprehensive weight obtained with this method could reflect
the importance of indicators objectively and reasonably. In order to solve the fuzziness and
subjectivity problem of evaluation language, criteria and process, a multistage fuzzy comprehensive
evaluation method is adopted to assess the comfort in civil aircraft cabin. Finally, a more objective
and quantitative result is obtained, which can give a feedback and direction to the designers. It is
proved to be an effective method.
