基于层次分析法的民用客机发动机技术评价与选型

层次分析法是1种有效实用的多目标决策方法。针对在大型客机研制中科学选择适合的民用航空发动机问题特点，基于层次分析法，将发动机的选型要求层次化分解，建立了指标技术评估模型，并考虑不同评估专家分配不同权重的方法。以现有民用发动机为例进行分析。分析结果表明：层次分析法在民用客机发动机选择中具有合理性、科学性，符合市场实际情况，适用于民用客机发动机方案选型，并可为民用客机发动机工程技术评估提供科学依据。

Technology Evaluation and Choice of Civil Aircraft Engine Based on Analytic Hierarchy Process

Analytic Hierarchy Process (AHP) is an effective and practical multi-objective decision-making method. Aiming at thecharacteristics of the suitable civil aeroengine selected scientifically in development of civil aircraft, the choice requirement of engine was decomposed hierarchically based on AHP. The evaluation model of index technology was built, and the method of different evaluation experts assigned different weights was considered. Taking the existing civil engine as example, the analysis results show that AHP is reasonable, scientific in the choice of civil aircraft engine, and fits market fact. The method is suitable for the scheme choice of civil aircraft engine, and provides the scientific basis for engineering technology evaluation for civil aircraft engine. Key words: AHP; civil aircraft; aeroengine; choice
