摘　　要：针对飞机生存力评估的必要性以及生存力评估中存在的模糊性和不确定性,提出了一种基于区间数的飞机生存力评估方法。从敏感性、易损性和作战能力3个方面构建了飞机生存力评估指标体系,基于区间层次分析法和信息熵法得到了飞机生存力的区间数形式的指标权重,利用权重系数法建立了飞机生存力的评估模型,最后进行了实例计算。结果表明,该方法能够较好地解决生存力评估中存在的模糊性和不确定性问题,从而使评估结果更客观。Since aircraft survivability evaluation is necessary and it is fuzzy and uncertain,a new evaluation method based on interval number was proposed.The index system for aircraft survivability evaluation was constructed by susceptibility,vulnerability and combat capability,the interval weights were calculated based on interval-based analytic hierarchy process and information entropy,the evaluation model of aircraft survivability was established based on weight coefficient.In the end,a numerical example was given.Cal-culation results show that the method is effective and feasible.
