Comprehensive evaluation model for integrative cabin environment quality of airliner

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.
