摘要: 网络流量分析是交通网络优化的基础,本文以中欧班列为研究对象,构建以总运输费用最小和运输时间最短为目标的双目标网络配流模型。其中,运输费用方面,考虑中欧班列与国际班轮和国际航空运输之间的竞争,采用两阶段博弈刻画区块链技术应用前后班列运价变化;运输时间方面,考虑区块链技术应用前后通关时间缩短比例以影响总时间。基于2020年中欧班列1周运行数据的分析结果表明,区块链技术应用对网络流量有显著影响。区块链技术应用后,东通道和中通道流量分别减少2.76%和5.12%,西通道流量增加7.88%,东通道和中通道的部分货物运输任务将向西通道转移。同时,网络总运输费用降低17.08%,总时间减少8.27%,综合运输成本降低了13.08%,有利于提升中欧班列的经济效益和对客户的吸引力。本文分析区块链技术应用前后中欧班列网络流量的变化,为班列开行方案调整和网络设施优化提供重要参考。

Abstract: Network traffic analysis is the basis of traffic network optimization. This paper focuses on the China Railway Express, and constructs a two-objective network assignment model with the minimum total transportation cost and the shortest transportation time. For the transportation costs, considering the competition between China Railway Express liner and international liner and international air transport, the two-stage game is used to depict the change in the freight rate of the liner before and after the application of blockchain technology. For the transportation time, the proportion of customs clearance time before and after the application of blockchain technology is considered to affect the total time. The analysis results based on the one-week operation data of the China Railway Express in 2020 show that the application of blockchain technology has a significant impact on network traffic. After the application of blockchain technology, the traffic of the East and Middle Passages will decrease by 2.76% and 5.12% respectively, and the traffic of the West Passage will increase by 7.88%. A part of the cargo transportation tasks of the East and Middle Passages will be transferred to the West Passage. At the same time, the total transportation cost of the network was reduced by 17.08% , the total time was reduced by 8.27% , and the comprehensive transportation cost was reduced by 13.08% , which is beneficial to improving the economic benefits and attractiveness of the China Railway Express to customers. This analysis of the changes in the network traffic of the China Railway Express before and after the application of blockchain technology in this paper can provide an important reference for the adjustment of the train operation plan and the optimization of network facilities.
