The market environment in which ports operate has changed dramatically, and this continuous process of change raises questions on the role of port authorities. This paper discusses the impact of some structural changes in international trade, transport and shipping on strategic and operational issues in the framework of port management. The central hypothesis put forward is that a successful port (authority), like a successful actor, must be prepared to constantly adopt new roles in order to cope with the changing market environment. The content and strategic scope of these new roles are highlighted, especially with regard to the European container port system. 相似文献

This paper reports the results of a scenario-based simulation study to explore mobility effects of an aging society in the
Netherlands. Four accumulative behavioral scenario variants, embedded in an economic and demographic scenario are used to
simulate possible future activity-travel patterns, using the Albatross system as the simulator. The variants account for likely
differences in activity-travel behavior between elderly today and elderly in the future. Trends ongoing over the last decade
in the Netherlands suggest that future elderly need to work longer, change their activity pattern with most growth occurring
in the social/leisure activity category, will try to avoid morning peak hours by rescheduling their activities and may introduce
more spatial diversity in terms of their residence location. Results show that these behavioral and spatial changes lead to
a significant increase in travel demands as well as temporal, spatial and modal shifts in mobility patterns. We discuss possible
policy implications of these predictions and evaluate the specific strength of activity-based models for studies of this kind.

Development and changes in port hinterlands have received considerable attention as they represent substantial opportunities to improve the efficiency of global freight distributions. Port regionalization was a concept brought forward by Notteboom and Rodrigue (2005) to articulate the emerging port hinterland dynamics in light of containerization, supply chain management and the setting of inland terminals. This paper expands this concept by focusing on a particular dimension of the regionalization paradigm concerning the evolving role of intermediate hubs. It is argued that, in addition to hinterland-based regionalization, there is also a foreland-based regionalization where intermediate hubs capture a maritime hinterland. This intensity and viability of processes of foreland-based regionalization depend on multiple geographical, technical and market-related factors, and this paper identifies and analyzes these underlying parameters. By doing so, it assesses whether foreland-based regionalization is simply a transitional phase in port development or, alternatively, represents emerging functional characteristics of contemporary freight distributions. 相似文献

This paper investigates the impact of a variety of travel information types on the quality of travel choices. Choice quality
is measured by comparing observed choices made under conditions of incomplete knowledge with predicted choice probabilities
under complete knowledge. Furthermore, the potential impact of travel information is considered along multiple attribute-dimensions
of alternatives, rather than in terms of travel time reductions only. Data is obtained from a choice experiment in a multimodal
travel simulator in combination with a web-based mode-choice experiment. A Structural Equation Model is estimated to test
a series of hypothesized direct and indirect relations between a traveler’s knowledge levels, information acquisition behavior
and the resulting travel-choice quality. The estimation results support the hypothesized relations, which provides evidence
of validity and applicability of the developed measure of travel-choice quality. Furthermore, found relations in general provide
some careful support for the often expected impact of information on the quality of travel choices. The effects are largest
for information services that generate previously unknown alternatives, and lowest for services that provide warnings in case
of high travel times only.

China plays an increasingly important role on the international economic scene and in global supply chains. Initially only coastal regions participated in global supply chains, but in recent years comparative cost advantages have led to an increased participation of inland destinations in China’s economic development. The growth of some inland regions has urged logistics players to revise and reconfigure their extensive logistics networks. This has been particularly the case in the Yangtze region. Upstream cities such as Chongqing are emerging as potential important production centres for the international markets. 相似文献

过去,偏重功能性的技术开发是可行的、甚至合理的。而时至今日,除价格、重量外,更多其它的标准变得日益重要,有时甚至能决定一个产品的市场成败。比如,盘式和鼓式制动器能造成许多噪声与振动现象,这些现象和声音可以描述为“颤抖”、“呜咽”、“尖叫” 相似文献

Logistics integration and network orientation in the port and maritime industry have redefined the functional role of ports in value chains and have generated new patterns of freight distribution and new approaches to port hierarchy. Existing models on the spatial and functional evolution of ports and port systems only partially fit into the new freight distribution paradigm. This paper aims to add to existing literature by introducing a port regionalization phase in port and port system development. It is demonstrated that the regionalization phase and associated hinterland concepts demand new approaches to port governance and a functional focus that goes beyond the traditional port perimeter. 相似文献

Annex VI of the MARPOL Convention aims for a reduction in sulphur oxide emissions from ships. The limits applicable at sea
in Emission Control Areas (ECAs) were reduced from 1.5% to 1% in 2010 and are planned to be further reduced to 0.1%, effective
from 1 January 2015. This paper analyses the impact of the International Maritime Organization’s Tier II/III standards introduced
by Annex VI amendments adopted in October 2008 on costs and prices of roro (roll on/roll off) traffic in the ECAs in North
Europe and on the competitiveness of roro shipping in the ECAs compared to trucking. We demonstrate that the new Annex VI
agreement may be quite costly for the participants in the shipping industry and will result in higher freight rates. Based
on a detailed price analysis on modal competition between the roro/truck option and the ‘truck only’ option on thirty origin–destination
routes linked to the ECAs, we conclude that the use of low sulphur fuel is expected to increase the transport prices particularly
on the origin–destination relations with a medium or long short sea section. The paper also presents the results of a survey
among leading short sea operators in the ECAs in view of providing more insight on expected modal shifts and price elasticity
in the short sea market. 相似文献

A submarine may have to operate for a period of time with local corrosion damage in the pressure hull if a suitable repair method is unavailable or too expensive for implementation. This paper describes collapse tests on twenty ring-stiffened aluminium cylinders, which were conducted to study the effect of corrosion damage on hull strength and stability. Artificial hull thinning was found to reduce the collapse strength of experimental models through high local stresses in the corroded region, leading to early onset of yielding and inelastic buckling. Bending associated with the eccentricity due to one-sided thinning was found to further increase the local stresses in the hull. Overall collapse pressures were more severely affected by corrosion damage than interframe collapse pressures. The percentage reduction in overall collapse pressure, compared with intact experimental models, was found to be closely related to the percentage depth of thinning. The accuracy of conventional collapse pressure predictions for the experimental models was significantly better for intact than for corroded cylinders. 相似文献
