Risk influencing factors analysis of Arctic maritime transportation systems: a Chinese perspective

Recently, the melting of Arctic sea ice and development of maritime technology are enabling the regular voyages in Arctic waters. However, the Arctic maritime transportation system (AMTS) is a complex and dynamic system with respect to human, technical, environmental and organizational issues. For example, ships operating in Arctic waters suffer severe weather conditions, fully and partially ice-covered waters, and are also difficult to search and rescue in ice-covered Arctic waters due to remoteness from lands. These risk factors will influence the safety and security of ships operating in Arctic waters. For this, this paper identifies potential risk influencing factors (RIFs) for the AMTS from human, technical (ship), environmental and organizational aspects. An analytical hierarchy process (AHP) method is used to analyze the hierarchical relationships and calculate the relative importance of the selected RIFs. Due to the complexity and uncertainty involved in the comprehensive analysis of RIFs for the AMTS, fuzzy sets are incorporated into AHP analysis to represent and treat the epistemic uncertainty. The identified critical RIFs in this study can be used to propose specific guidance for the operations of crews on board, ship owners, and ship managers.     

Themes and tools of maritime transport research during 2000-2014

This study examines how maritime transport has been researched through a comprehensive review of papers published in 19 transportation journals over the period 2000–2014. Systematic investigation shows that Maritime Policy & Management plays a prominent role in publishing maritime transport research. At the same time, ‘shipping’ is a dominant research area, with ‘port management, service, performance, efficiency and competitiveness’; ‘shipping market, industry, freight rate and economic impact’; and ‘terminal studies’ as the most popular topics. Nevertheless, few efforts have investigated ‘shipping finance’; ‘shipping service’; or ‘port risk and security.’ Since 2000, the use of quantitative analysis techniques has steadily increased in maritime transport to help participants make decisions scientifically. We here present the major data analysis techniques and highlight some limitations regarding their application. Thus, we provide a better understanding of how maritime transport research has been undertaken in a quantitative manner.     

长江口12.5 m深水航道利用边坡通航的方案

长江口深水航道是大型海船进出上海港主要港区和长江下游主要港口的重要航道。随着大型集装箱、邮轮、散货船在北槽深水航道有限的宽度内通航矛盾日益突出,对深水航道的稳定运行与上海港的日常运营造成极大的影响。在分析长江口现有通航船舶特点及矛盾焦点的基础上,结合长江口航道资源分析,探讨利用长江口深水航道边坡进行超宽船舶交会的可行性及其优势,并提出相关实施措施。该方案是提高长江口12.5 m深水航道资源利用率,贯彻落实供给侧改革,适应"长江经济带"和"一带一路"两个重大国家战略、推进上海国际航运中心建设的有效措施。     

Mapping and evaluating the complexity of information flows in freight transport chains

ABSTRACT

The role of information in the efficient management of freight transport systems is well acknowledged. Administrative functions, such as negotiation or payments, involve intensive communication, while the production of the transport service relies heavily on the sharing of information (e.g. track and trace). Yet, specific literature on information flows is relatively scarce. This paper sets out to contribute to filling in this gap. Firstly, it elaborates a set of maps of the information flows for four conceptualisations – direct link, corridor, hub and spoke, and connected hubs – of maritime freight transport, initially proposed by Woxenius (2007, “Generic Framework for Transport Network Designs: Applications and Treatment in Intermodal Freight Transport Literature.” Transport Reviews 27 (6): 733–749. doi:10.1080/01441640701358796). The results reveal a high degree of similarity between import and export services. Secondly, it assesses the complexity of each conceptualisation’s flow network using the concept of entropy. Flows are characterised along four variables: involved agents, timing, and contents and message type. Additionally, a new taxonomy is proposed to categorise the messages. The results evidence the heterogeneous contributions of each category to the complexity of the flows. Finally, the results also reveal that the information flows for the tasks in the pre-transport stage are not specific to the conceptualisation in question and are of comparable complexity to the flows occurring during the transport stage.     

国际货物运输中的隐名代理问题

随着我国对外贸易事业的深入开展,国际贸易中的隐名代理问题亟须规范化。起源于英国的隐名代理制度,在英美法系由来已久日趋完善。世界上大多数国家都参照英国的隐名代理制度,制定了有关隐名代理的法律规范。我国目前虽然规定了一些有关隐名代理问题的实务操作办法,但缺少对隐名代理相关法律问题的明确规范,建议通过立法的形式对隐名代理制度予以完善。

疫情不同阶段西部陆海新通道市场分担率变化研究

为探究全球新冠肺炎疫情波动变化背景下西部陆海新通道对解决中欧集装箱货运问题的影响，本文利用中欧集装箱运输数据，以集装箱海运班轮运输路线、中欧班列运输路线和西部陆海新通道路线为选择肢，分别构建多项式Logit模型和混合Logit模型进行对比分析，探索疫情3个阶段下托运人对中欧集装箱运输的路线选择决策机制；并在疫情不同时期内，估算陆海新通道运输属性的主观值。研究结果表明：托运人对于中欧集装箱运输的路线属性在不同疫情时期内具有不同的个体异质性，货物的时间价值随疫情严峻性增加而稳步增加，延迟时间价值增加幅度先快后慢。在疫情松弛期，陆海新通道的市场分担率主要受自身运输费用和班轮的运输时间影响；疫情平稳期，主要受自身和班轮运输时间影响；疫情严峻期，主要受自身延迟时间影响。疫情时期，陆海新通道在西部省市承担的集装箱货运量比例总体持续增长且增速较快；在疫情平稳期，中西南部地区增速较快；疫情严峻期，西北部地区增加明显。
