考虑节点度的供应链网络风险模糊评估

Risk fuzzy evaluation of supply chain network based on node degree

从复杂网络角度将供应链网络风险分为"点中断风险"和"边中断风险"两大类,并重新定义了各自的主要风险要素.在此基础上,将网络的节点度指标引入风险评价中,建立了供应链网络风险的双层双维模糊评估模型.最后,以某三级供应链网络为例,由"微观"到"宏观"逐级对供应链网络风险进行了定量评估,仿真结果表明企业节点的度值作为供应链网络风险评估的过渡参数,可以有效提高评估结果的准确性.

This paper divides supply chain network risk into risk of point stoppage and risk of connect- ing stoppage from complex network perspective, redefines the separate main risk factors. Based on this, it brings node degree into risk assessment, and a double levels-dimensionality fuzzy evaluation model is developed to evaluate supply chain network risk. Taking a three-level supply chain network as an illustration, a quantitative risk evaluation is carried out from microcosmic to macroscopic. The re- sults show that the node degree of company which serves as a transfer parameter can improve the accu- racy of assessment result.
