基于社会网络分析的供应商韧性综合评价

Comprehensive evaluation of supplier resilience based on social network analysis

在供应链中断和暂停风险不断加剧的背景下,供应商韧性综合评价在提高供应链稳定性中发挥着重要作用。采用文献分析法确定供应商韧性评价准则,运用层次分析法为各评价准则赋权,根据决策者之间的社会网络关系,利用Louvain算法进行社区划分,并利用度中心性和特征向量中心性确定决策者和子群体权重,构建供应商韧性评价模型,通过某新能源企业选择电池供应商的算例验证了方法的适用性。结果表明:该评价模型能够有效评估供应商的韧性水平,有利于帮助企业选择出高韧性的供应商,提高企业的抗风险能力,从而促进企业的长期稳定发展。

In the context of increasing risks of supply chain disruptions and pauses,a comprehensive evaluation of supplier resilience is paramount for enhancing supply chain stability.This study determines the criteria for evaluating supplier resilience through literature analysis and uses the AHP to assign weights to each criterion.Based on the social network relationships among decision-makers,the Louvain algorithm is employed for community detection,and degree centrality and eigenvector centrality are used to determine the weights of decision-makers and subgroups.A supplier resilience evaluation model is constructed,and its applicability is validated through a case of a new energy company selecting battery suppliers.The results show that this evaluation model can effectively assess the resilience levels of suppliers,helping enterprises choose highly resilient suppliers,thereby enhancing their risk resistance capability and promoting long-term stable development.
