【摘要】 针对地震灾害下应急物流系统(ELS)绩效评价的问题,以地震灾害下的应急物流系统为研究对象,首先建立了ELS运作模型,并对该运作模型进行了分析;然后构建了地震灾害下应急物流系统绩效评价指标体系,并在上述基础上建立了基于BP神经网络的评价模型;最后将该评价方法应用于实例,验证了该评价方法的科学性和实用性。更多还原

【Abstract】 In order to solve the problem of the performance evaluation for earthquake disaster emergency logistics system(ELS),this pap er studied earthquake emergency logistics system.Firstly,established the ELS operating models and analyzed the operation of the model;secondly,built an earthquake emergency logistics system performance evaluation index set,and then,built evaluation model based on BP neural network;finally,applied the evaluation method to the instance and the scientific and validated practical of the evaluation method.更多还原
