Some evidence has emerged of second-tier hubs inserting themselves between hubs and feeder ports, producing a new hierarchy of port networks. This article aims to establish the dynamics of this process based on illustrative cases in Asia, South America, and Europe. Findings reveal spatial factors to include a cluster of small ports with minimal sailing distance within a given range, suitable channel and berth depth, and ideally high capacity inland links. From the economic perspective, demand-side factors include a local captive market and aggregated demand to be captured from other ports, while supply-side factors include diseconomies of scale at traditional hubs, an increase in direct services, an increase in large feeder vessels calling from first-tier hubs which are then transhipped to smaller feeders for serving local ports, and an increase in overland servicing of local smaller ports. From a strategic perspective, vertical and horizontal integration in the shipping sector has produced extensive network economies, whereby shipping lines look to create group-specific port hierarchies, enhanced in the presence of aggressive management strategies and supportive policies. This finding suggests that proactive port stakeholders can in certain circumstances seize the opportunity to capture this role within their port range. 相似文献

The ports of Mediterranean basin have experienced significant growth in container traffic over the last decade. In the western Mediterranean two distinct types of port have emerged: the established ports of the northern part of the basin which serve a gateway function and a set of new ports in the south which act as transhipment hubs. In this paper we explore the dynamics of change and reveal how growth is driven by shifts in individual trades. While the hub ports are integrated into Asian pendulum services, the gateway ports are experiencing growth because of new direct services to Asia and North America. We suggest that the distinctions between the transhipment hubs and the gateway ports are becoming blurred, especially because the gateway ports are also assuming greater transhipment roles. We also explore whether this new dynamism in the Mediterranean ports is reversing the long-standing hinterland domination of the ports of the northern range. We demonstrate that the gateway ports of the western Mediterranean continue to serve local and regional markets, with very limited penetration north of the Alps and Pyrenees. This is due in part to difficulties with rail services but also because of the continued efficiency of the northern range ports and their hinterland connections. We suggest that in the short run, at least, little change is likely. 相似文献

A genetic algorithm for the hub-and-spoke problem (GAHP) is proposed in this work. The GAHP configures a hub-and-spoke network
with shuttle services for containerized cargo transport. For a fixed number of hubs, it determines the best network configuration
of hub locations and spoke allocations that minimizes the total costs of the system. The GAHP has a simple individual structure
with integer number representation, where spokes, their allocations, and hub locations are easily recognized. Due to the characteristics
of the problem, which has fixed number of hubs, rearrangements should be performed after every process. The GAHP rearrangement
process includes improvements of individual structures, resulting in an improved population. Before applying the GAHP to the
container transport network problem, the algorithm is validated using the Civil Aeronautics Board data set, which is extensively
used in the literature to benchmark heuristics of hub location problems. To illustrate an example of a hub-and-spoke network
with shuttle services, a study case with 18 ports is analyzed. 相似文献

A hierarchized container ports network, with several super hubs and many multilevel hub ports, will be established, mainly serving transshipment and carrying out most of its business in the hub-spoke mode. This paper sums up a programming model, in which the elementary statistic units, cost and expense of every phase of any shipment are the straight objects, and the minimum cost of the whole network is taken as the objective. This is established based on a dynamic system to make out the hierarchical structure of the container ports network, i.e. the trunk hub and feeder hubs can be planned in a economic zone, then the optimal scale vector can also be obtained for all container ports concerned with the network. The vector is a standard measurement to decide a port's position and their scale distribution in the whole network. 相似文献

This paper investigates the centrality of cruise ports in the Asian cruise shipping market while proposing the hubs and authorities centrality (HACC) metric as a directional synthesis of the hubs centrality and authorities centrality to explore cyclical and directional features of centrality in the cruise shipping network. With the development of the cruise shipping industry, research has been actively conducted with a particular focus on identifying the characteristics of hub ports. This paper employs social network analysis to investigate the HACC which is originally developed for analyzing the cruise port centrality problem. Empirical study implies that Ho Chi Minh City, Hong Kong, Nagasaki, Penang, Phuket, Port Klang, Shanghai, and Singapore (in alphabetical order) reflects particulars of cruise hub ports. One of the exceptional results of this paper is Ho Chi Minh City, Penang, Phuket, and Port Klang have demonstrated high HACC (refers to hub ports) while limited degree and betweenness centrality. In contrast, Busan and Keelung are not classified as hub ports. 相似文献

<正>改革开放以来,现代港口建设取得长足进步,做出了历史性贡献,但与我国现代化和综合交通运输业战略发展要求相比,无须讳言,尚有相当的差距,特别是要建设有中国特色社会主义现代化,在加速“两个根本转变”中,当前港口内外面临着诸多深层次矛盾,困难和问题差距,其中包括: 1.货源不足 管理粗放 其直接原因:一是传统陆上腹地经济结构调整优化和国企改革到位,尚待时日,至少还需二、三年时间;二是港口对临港货源基地建设自觉性不高,货源自组、自协调供给能力不足;三是陆上货源不足,又缺少吸引海外中转货源政策支持力度;四是港口群体缺少功能互补, 相似文献
