摘　　要：对应急物流保障能力进行全方位有效的评价可以促进应急物流保障体系的构建和完善,保障应急物流的顺利实施,从而降低突发事件的影响。由于应急物流的突发性、时间约束的紧迫性和弱经济性,传统的主观确定指标权重方法在评价上存在缺陷。本文针对应急物流构建了评价指标及模型,针对传统的单一专家主观确定权重的方法进行了改进,采用信息熵客观评价和主观评价相结合的方法进行应急物流系统的可靠性评估。通过指标分析,对评价指标进行综合筛选,确立评价指标体系。通过三角模糊矩阵的建立,设计了指标熵、指标总熵以及组合权重的计算方法,运用模糊熵评价将信息度量反映到组合权中,然后运用关联函数进行了综合评价,从而建立了基于模糊熵的应急物流保障能力评价模型。给出一个实例,采用文中设计的方法得出相应的评价结果。The comprehensive and effective evaluation for capability of emergency logistics system can promote the construction and improvement of the emergency logistics system ef- fectively. Because of burstiness, weak economy, time-uncertain of emergency logistics system, constructs the operation model and its evaluation index system for emergency logistics system. In view of the imperfection of subjective determining index weight method in tradi- tional evaluation, the index weight coefficients are determined by information entropy method of combining subjective judgment with objective evaluation. First of all, established the evaluation index system through the index analysis. Secondly, established the triangular fuzzy matrix, and designed the calculation method of entropy weight and combination weights for each index. Then, comprehensively evaluate emergency logistics system combined with analytic hierarchy process and correlation function. Finally, obtains a specific solution steps based on an example.
