基于供应中断风险下生鲜农产品供应链网络节点重要性评价研究
Evaluation of the Importance of Fresh Produce Supply Chain Network Nodes Based on the Risk of Supply Disruption

随着人民对于生活质量的更高追求以及现代物流供应链的不断完善，生鲜农产品供应链网络得到了飞快的发展。但是由于生鲜农产品供应链上下游节点企业易受到外界各因素的干扰，从而存在供应中断风险，影响供应链网络整体的运行。因此，本文首先根据生鲜农产品供应链的特点和业务流程，结合复杂网络理论，构建其网络拓扑结构图。接着采用三角模糊数的方法确定网络拓扑结构图各边的权重，并引入节点重要度贡献矩阵和网络效率来表征各个节点在供应链网络局部和全局中的重要性。基于此，对供应链中的重要节点采取必要的预防措施，来增强供应链的抗风险能力。最后，通过实证分析对生鲜农产品供应链中各个节点的重要性进行计算和排序，验证了该评估方法的有效性和实用性。
With the people’s higher pursuit of quality of life and the continuous improvement of the modern logistics supply chain, the supply chain network of fresh agricultural products has developed rap-idly. However, due to the fresh agricultural products supply chain upstream and downstream node enterprises are susceptible to the interference of external factors, thus there is a risk of supply in-terruption, affecting the overall operation of the supply chain network. Therefore, this paper firstly constructs the network topology diagram of fresh agricultural products supply chain according to its characteristics and business process, combined with complex network theory. Then the triangu-lar fuzzy number method is used to determine the weights of each edge of the network topology graph, and the node importance contribution matrix and network efficiency are introduced to characterize the importance of each node in the supply chain network locally and globally. Based on this, necessary preventive measures are taken for the important nodes in the supply chain to en-hance the risk resistance of the supply chain. Finally, the importance of each node in the supply chain of fresh agricultural products is calculated and ranked through empirical analysis, which ver-ifies the effectiveness and practicality of the assessment method.
