基于效用理论的飞机客舱布局选型研究

Research on Aircraft Cabin Layout Selection Based on Utility Theory

在综合考虑安全性、经济性和舒适性等因素的前提下,建立了量化评价客舱布局备选方案的二级指标体系;运用效用理论定义了基于评价指标体系的效用函数和效用矩阵,采用层次分析法将客户的个性化需求定量化表示成评价指标的权重差异,提出了确定最佳方案的加权效用值计算方法.以B787飞机的客舱布局选型为例,针对某家航空公司的定制需求,得到了该家航空公司的客舱布局最佳方案.实例分析结果表明模型的合理性.

The utility theory is used for defining the utility functions and utility matrix based on the e‐valuation index system .Furthermore ,the individual demands are quantitatively processed as different weights in evaluation index system with analytical hierarchy process .Thus ,the calculating method of determining the best layout scheme could be put forward by weighted utility values .In the example of B787 cabin layout selection of the airline’s individual demands .The airline could obtain the most suit‐able scheme by modeling .T he results verify the reasonable of modeling ,w hich provides an objective and scientific basis for aircraft cabin layout selection .
