【摘要】：应急物资是应对自然灾害、突发公共卫生事件、公共安全事件及军事冲突等所必需的保障性物品,其需求具有不确定性、时效性及滞后性等特点。合理选择应急物资供应商是各部门应对新挑战、构建现代应急保障模式的重要环节。在分析应急物资供应商评价指标基础上,结合熵权法和复杂比例评价(COPRAS)方法建立了应急物资供应商评价模型。最后,通过算例分析了该方法的具体应用过程,并结合各供应商效用度的排序给出最佳应急物资供应商选择策略。
[Abstract]:Emergency supplies are necessary to protect against natural disasters, public health emergencies, public safety incidents and military conflicts. Their demand is uncertain. The reasonable selection of emergency supplies suppliers is an important link for all departments to meet the new challenges and construct the modern emergency support model. Based on the analysis of the evaluation index of emergency supplies suppliers, Combined with entropy weight method and complex proportion evaluation method, the evaluation model of emergency supplies supplier is established. Finally, the concrete application process of this method is analyzed through an example. The optimal supplier selection strategy of emergency supplies is given according to the order of utility degree of each supplier.
