摘要
研究复杂供应链网络的效率和重要节点识别问题。由于现代供应链网络的复杂性,以节点度分布作为衡量供应链枢纽节点,并不符合供应链运行的实际情况。传统的网络效率计算方法只是简单地进行"去边"和"去点"计算。为了解决上述问题,首先建立了一个典型供应链模型,然后提出了在突发情况下新的对于供应链网络效率计算方法。仿真结果表明,方法可以有效衡量供应链的网络效率,并能识别供应链网络中最具影响力的节点,从而能够针对性地对供应链网络进行防护,提高运行效率。
The network efficiency and key node identification of complex supply chain were studied. The tradi- tional network efficiency calculation method was simply based on ＂edge deletion＂ or ＂node deletion＂. Because of the complexity of the modern supply chain network, the method distinguishing the key node of supply chain based on the degree distribution, was not consistent with the actual operation of the supply chain. To solve the above problem, first, a typical model was established. Then a new network efficiency calculation method was put forward to calculate the supply chain model. Simulation result shows that this method can be used to measure the network efficiency and identify the most influential node. Thereby, it is helpful in protecting the supply chain network.
