石油公司检查演绎完美风暴

由于世界石油资源高度垄断,大型石油公司不仅可以支配石油资源,对石油运输也扮演着关键性角色.长久以来,世界各大油运公司都接受其严格的挑选和检查.然而,随着石油公司对油污事故所承担的责任不断加大,油公司不再满足于对船舶的检查,而转向同时对油轮船东的管理进行控制.2004年,油轮管理与自我评估体系(TMSA)问世,现已升级为第二版.目前,各油运公司都在积极地走上TMSA之路,但对于这一新的管理理论,在操作和理解上仍在不断探索,如何打开TMSA之门,使其理念不断提升?为此,本刊记者专访了香港海宏轮船公司副总张作勋先生,请他结合自身多年的经验对此作详细解读.

基于势流的水下滑翔机的飞行模拟器(英文)

Underwater gliders are recent innovative types of autonomous underwater vehicles (AUVs) used in ocean exploration and observation. They adjust their buoyancy to dive and to return to the ocean surface. During the change of altitude, they use the hydrodynamic forces developed by their wings to move forward. Their flights are controlled by changing the position of their centers of gravity and their buoyancy to adjust their trim and heel angles. For better flight control, the understanding of the hydrodynamic behavior and the flight mechanics of the underwater glider is necessary. A 6-DOF motion simulator is coupled with an unsteady potential flow model for this purpose. In some specific cases, the numerical study demonstrates that an inappropriate stabilizer dimension can cause counter-steering behavior. The simulator can be used to improve the automatic flight control. It can also be used for the hydrodynamic design optimization of the devices.     

How do ocean carriers organize the empty containers reposition activity in the USA?

The routing of empty containers is an unavoidable activity of the intermodal chain. In fact, import containers that arrive at a national port are sent toward a multiplicity of interior destinations. Then the empty containers must return to a port to accomplish an export voyage. The purpose of this paper is to analyse the organizational choice of ocean carriers to reposition their empty containers in the USA. Ocean carriers have four options to relocate their empty containers: the spot organization and the adoption of three different renewable contracts to frame the externalization. How do ocean carriers choose their organization form to relocate their empty containers?     

Some insights into competition between low-cost airlines

The phenomenon of the wide world growth in low-cost airlines has resulted in a focus on their pricing strategies, on issues of cost recovery and on their impact on the traffic and market shares of legacy carriers or other low-cost carriers when they are in competition, either directly or at adjacent airports.This paper provides a brief overview of the characteristics of these low-cost carriers as well as their history and geography. It goes on to outline ways in which these carriers compete and manage demand, ranging from price competition to advertising; some of these methods directly reflect their special characteristics. Some empirical evidence is presented which indicates a correlation in fare setting behaviour between competitors and insights are offered on cost recovery.The impact of the start-up of low-cost carriers is also analysed, focusing on their impacts on other low-cost carriers. The case of Ryanair competing with easyJet on London-Venice is examined along with Southwest and Frontier on Denver-Las Vegas.     

Round-the-world service: The rise of Evergreen and the fall of U.S. Lines

In the mid-1980s two very large steamship lines, Evergreen Marine Corporation and United States Lines, inargurated round-the-world (RTW) container ship service. The concept of tying together major transoceanic trade routes in a complete global network is feasible provided that the cargo volumes and freight revenues are sustainable. United States Lines employed enormous new container ships in their one-directional RTW service while Evergreen used frequent sailings of somewhat smaller vessels both eastbound and westbound in their RTW service. United States Lines, unfortunately, was unable to obtain sufficiently high load factors or enjoy sufficient economies of scale to survive whereas Evergreen, emphasizing their high quality service, not only survived but have continued their successful operations to this day.     

Computing airfare elasticities or opening Pandora's box

Airfare elasticities are crucial for policy instruments for the stakeholders of tourism industry. Modellers attempting to estimate these elasticities face several challenges in the absence of microeconomic data on consumer preferences. The aim of this paper is to offer a critical analysis of the practice of computing airfare elasticities from tourism demand studies. It identifies and discusses potential sources of measurement errors in the data and drawbacks that investigators face and assesses their implications for the estimated parameters in the respective models. The use of price of crude oil and distance between origin and destination as proxies for transportation costs are evaluated. It is recommended that authors be more systematic in reporting their results. They need to comment on the limitations of their elasticity estimates since these have repercussions on policy recommendations made based on their results.

Operational performance evaluation of major container ports in the Asia-Pacific region

If international container ports are to gain a proper appreciation of their various advantages, disadvantages and potential opportunities in a globally competitive environment, it is essential that they conduct effective evaluation of their operational performance. The present study applies five models of data envelopment analysis (DEA) to acquire a variety of complementary information about the operational efficiency of major container ports in the Asia-Pacific region and to identify trends in port efficiency. The study first establishes the causes of inefficiency on the basis of efficiency value analysis. Slack variable analysis is then used to identify potential areas of improvement for inefficient ports. This is followed by the utilization of return to scale analysis to assess whether each port is in a state of increasing, decreasing, or constant return to scale. Finally, a sensitivity analysis is conducted to identify which input or output variables have larger weights in terms of efficiency. The results provide valuable information for port managements in their attempts to establish competitive strategies for the future and to improve their resource utilization for ongoing improvements in operational efficiency.
