摘要:

为分析并测算全球新型冠状病毒肺炎(COVID-19)疫情下以中欧、中亚班列为代表的国际班列通道的综合风险,便于决策者因险施策、防患于未然。首先,构建疫情下通道沿线节点国家综合风险评价指标体系,采用模糊C均值(FCM)聚类算法对沿线国家风险等级进行分类;然后,综合考虑节点间风险的相互影响,构建通道风险测算模型;最后,利用蒙特卡罗法进行仿真试验,计算不同通道去向、返程班列的风险得分。结果表明:中欧班列中/东向通道风险最高,中亚班列南向通道、新通道通行风险相对较小,需有效开拓南向通道和新通道,分担通道货运高风险。

Abstract:

In order to analyze and measure the comprehensive risk of international freight train routes such as China-Europe and China-Asia freight train routes under the global COVID-19, this paper aimed to help policy makers to take preventive measures. Firstly, the comprehensive risk evaluation index system of the countries along the corridor under the epidemic situation was constructed, and FCM was used to classify countries along the corridor by risk levels. Then a routing risk measurement model considering interaction between nodes was constructed. Finally, Monte Carlo method was used to simulate the experiment, so that the destination and the return train risk scores of different routes were obtained. The results show that the central/eastbound channel of China-Europe freight train routes have the highest risk, while the southbound channel and new channel of China-Asia freight train routes have relatively low risk. Therefore, it is necessary to effectively develop the southbound channel and new channels to share the freight risk of high channel.
