摘要： 针对保障领域重保障能力评估而轻薄弱环节查找的现状，提出一种通过求解保障能力各指标薄弱度确定薄弱环节的方法。薄弱度由指标裕度空间和权重共同决定，采用主成分分析法求其权重，应用集对分析优化指标裕度空间。实例表明，利用该方法求出的薄弱环节改进方案与其他2种方法确定的方案相比是最优的，能提高保障资源配置合理性。

Abstract: Aiming at the current situation that pays much attention to support capability evaluation while pays little attention to seeking out the weakness link of support capability, this paper puts forward a kind of method to ensure the support capability weakness link through getting the weakness degree of each index. The weakness degree is determined by index margin space and weight, by making use of the Principal Component Analysis(PCA) to ensure the weight of each index and optimizing the index margin space by applying the set pair analysis. Example indicates that the method put forward can be used to obtain the optimum amelioration project for the weakness link and station the support resources reasonably.

Key words: support capability evaluation, Principal Component Analysis(PCA), weakness degree, margin space, set pair analysis
