为保障集装箱海运网络稳定运行，提出集装箱海运网络的脆弱性风险控制方法。选取集装箱海运网络平均度、集装箱海运网络孤立节点比例、集装箱海运网络效率等作为脆弱性风险控制指标，采用熵权法计算各指标权重，基于指标权重构建脆弱性风险划分模型，将集装箱海运网络的脆弱性风险划分为不脆弱~非常脆弱5个等级，根据脆弱性风险等级划分结果，提出对应的策略与建议，实现集装箱海运网络脆弱性风险控制。实验结果显示该方法可有效获取脆弱性风险等级划分结果，并有效降低集装箱海运网络脆弱性风险。
To ensure the stable operation of the container shipping network, a vulnerability risk control method for the container shipping network is proposed. The average degree of container shipping network, the proportion of isolated nodes in container shipping network, and the efficiency of container shipping network are selected as the vulnerability risk control indicators. The entropy weight method is used to calculate the weight of each indicator. Based on the weight of the indicators, a vulnerability risk classification model is constructed. The vulnerability risk of container shipping network is divided into five levels, namely, non fragile to very fragile. According to the classification results, Put forward corresponding strategies and suggestions to realize vulnerability risk control of container shipping network. The experimental results show that this method can effectively obtain the results of vulnerability risk classification, and effectively reduce the vulnerability risk of container shipping network.
