摘　　要：建立了飞机战伤抢修性评价体系,同时为了合理引入抢修性评价过程中的专家分歧,提出了基于特征的集对分析评价模型.该模型首先将评价矩阵进行奇异值分解,提取对矩阵特征贡献率大的奇异值进行分解逆运算,然后以集对分析的同异反联系度为基础,对数据进行集对分析.应用上述评价体系和评价模型对某型飞机进行了抢修性评价.应用表明:该评价模型具有很好的可行性和有效性,适当引入专家分歧使得集对分析结果更加合理化.An evaluation system was set up for aircraft combat resilience （ACR）,and a SPA evaluation model was developed on the basis of characteristic feature with the divergencies of experts’ views taken into account during the evaluation of combat resilience.In the evaluation model the singular values are decomposed in the evaluation matrix,and the singular values which make important contribution to the matrix characteristics are extracted for inverse decomposing operation of the evaluation matrix.Then,an SPA is made,based on IDC.An evaluation example of a certain battle damaged plane to be repaired was given to illustrate the proposed evaluation system/model practically.The results showed that the evaluation model is highly feasible and effective,and introducing properly the divergences of experts’ views into SPA will enable the evaluation results to be more rational.
