Abstract:
The airlines need to select the optional equipment according to their individual development demands and the manufacture′s standard specification manual when purchasing a new airplane. For this customization process, the selection theory is mainly based on qualitative analysis and quantitative analysis. The grey incidence analysis (GIA) is used for modeling, which evaluates the correlations between optional equipment and airlines′ individual demands. Meanwhile, the customization demands are quantitatively processed as different weights in evaluation index system with analytical hierarchy process. Then, the value of grey incidence degree is obtained which shows whether the optional equipment is on the purchasing list or not. Finally, two airlines′ customization demands are applied in the example of aircraft cabin′s sea ts, so two different purchasing priorities and equipment installation lists can be obtained. The results and comparisons verify the reasonable of modeling, which provides an objective scheme of aircraft equipment selection.
