Priority Evaluation of Civil Aircraft Design Optimization Based on Competitiveness Model

This article proposed and constructed a competitiveness evaluation model based on stakeholder satisfaction as the evaluation criterion for single-aisle passenger aircraft in service. During competitiveness modeling, the analytic hierarchy process method was applied to determine the weights of stakeholders and the attributes they concern. And the attribute parameters were normalized in a sigmoid function to make the evaluation more reasonable. Three pending optimization projects were evaluated and prioritized by the competitiveness model. The drag reduction optimization project which could reduce the direct operating cost without negative impact on aircraft attributes is the most effective way to enhance the overall competitiveness.
