摘要: 针对旅客机座舱综合环境质量评价问题,提出一种模糊综合评价模型.其采用分层评价体系,将座舱热环境、座舱空气质量以及座舱声、视、安全环境作为评价模型的第一层,各环境要求的具体评价因素作为评价模型的第二层,应用模糊综合评价方法,将两层因素结合在一起.在第二层次中,根据对座舱环境的影响,合理区分其重要程度,利用模糊运算得出初级评价结果,利用层次分析法,确定第一层次三方面的权重系数,从而得出座舱综合环境质量的评价结果,并通过求重心的方法解决了最大隶属度不适用的情况.还通过对具体实例的应用,证实了模型的可行性和合理性.Abstract: To study the evaluation for integrative cabin environment quality of airliner, a comprehensive evaluation model using a stratified evaluation system was proposed. Thermal environments, cabin air quality and acoustical, visual and safe environments were assumed to be the first layer of an evaluation model, while specific evaluation factors were taken as the second layer of the model. Through the method of a fuzzy comprehensive evaluation the factors of the two layers were joined together. According to the effect on the cabin environments, the weight coefficients in the second layer were confirmed and the primary result of evaluation was given by applying the fuzzy operation. The weight coefficients of the first layer were given by applying analytic hierarchy process. Then the result of comprehensive evaluation of cabin environment quality was obtained. By solving barycenter of the result of comprehensive evaluation, the question when the maximum subjection value was not applicable was solved. The feasibility and rationality of the model is substantiated through some specific cases.
