不确定条件下应急供应链可靠性评价模型

以应急供应链可靠性为评价对象,在对其影响因素进行分析的基础上,从保障机制、信息系统、网络结构、运作流程、资金保障五个方面构建了评价指标体系,考虑应急供应链可靠性评价信息受主客观因素影响难以精确测定,依据指标特点运用语言评价值,区间值,数值多种形式测定指标值,然后将语言评价值和数值转化为区间值,运用层次分析法、熵值法分别计算一、二级指标权重,再运用联系数对指标值和权重进行集结排序。最后设计算例验证了模型的有效性和适用性。

Evaluation of Emergency Supply Chain Reliability Under Uncertain Information

The paper discusses the reliability of the emergency supply chain. Emergency supply chain is a powerful tool for dealing with emergencies. The evaluation of emergency supply chain reliability has a crucial significance to meet the resource needs of affected people and relief organizations. Based on the conclusion of the historical achievement and implementation experience of emergency supply chain, first, we analyze the elements of emergency supply chain reliability from the protection mechanism, information system, network structure, operation of the process. Second, the evaluating marks of the elements are described as interval, linguistic assessment information, number. Then, we aculeate the evaluation result using triangular fuzzy number, entropy, analytic hierarchy process, and contact number. Last of all, an example is designed and it shows the feasibility and applicability of this model.
