浅议黄河古贤水库的航运开发

黄河古贤水库是黄河干流在我省规划建设的一座特大型水库,本文根据水库规划资料和两岸经济、旅游资源情况,提出了水库航运发展设想,以及航道建设规模、港口码头布局、船舶运输方式。     

空重箱混合运输条件下集装箱海运网络优化研究

随着国际集装箱运量的迅速增加和国际贸易不平衡的加剧,集装箱供需矛盾日益突出,空箱调运优化问题亟待解决.文中以实现网络总成本最小为目标,建立了空重箱混合运输条件下的集装箱海运网络优化模型,同步优化国际集装箱海运网络的航线配置、空箱调运方案、集装箱船服务频率及船型配置,并通过算例分析,验证了该模型具有实用性和可操作性.

以复杂网络理论为基础,分析海运网络的拓扑结构具有无标度网络特性,可运用BA无标度网络模型构建演化海运网络.连接概率是BA模型中节点优先连接的重要依据,据此,针对海运网络港口节点进行研究,通过加权量化和MATLAB编程将影响节点间连接的因素组成节点吸引度,引入连接概率公式,改进了BA模型.分别选取2010年全球15个和25个主要集装箱港口的相关数据,运用上述改进BA模型分别得到不同规模的海运网络演化情况,演化结果验证了海运复杂网络具有无标度网络特征,呈现的特性与网络规模没有必然联系,规模大的网络平均路径更长、集聚性更强,度值相差更悬殊.进一步运用全球班轮航线实际网络进行验证,得到两者结构特性基本相同.     

Investor herding behaviour in globally listed shipping stocks

ABSTRACT

This study undertakes one of the first empirical attempts to investigate and contribute a set of innovative findings to investor herding behavior and herding spillover effects in globally listed shipping company stock returns. Distinguishing between OECD and Non-OECD markets, herding behavior is tested on a diversified set of shipping companies traded in international equity markets, over different business cycle phases, financial crises, and external shocks. A set of dynamic models, well established in the relevant behavioral finance literature, is implemented. Empirical evidence indicates investor herding behavior in shipping stock returns and herding spillover effects between different shipping sectors, albeit not robust in all cases. These challenging findings can have a material impact on efficient investment and financing decisions of shipping market players.

基于多层次模糊评价法的航运企业人力资源绩效综合评价

全球经济危机过后,远洋船舶运力过剩,航运企业普遍亏损,在这种态势下,人才无疑是企业最宝贵的财富。由于航运业的特殊性,其人力资源主要为船员和岸基工作人员两大类,船员的工作性质与岸基工作人员有很大的差别。文中主要研究建立航运企业针对两类人员的综合绩效评价指标体系和模型,运用多层次的模糊综合评价方法,获得各个指标权重及相应的评判值。并通过对某航运公司的人力资源进行评价证明了模型的有效性,为航运企业建立科学的人力资源绩效考评机制提供帮助。     

大扰动下的船舶电站暂态仿真分析

针对目前在船舶电站暂态稳定分析中普遍采用的仿真工具MATLAB/Simulink算法受限且仿真时间过长的不足,应用时域仿真法建立船舶电站的数学模型,再用基于隐式梯形积分法的C#.NET程序对其求解。通过对仿真结果的分析验证了仿真方法的有效性。     

Atmospheric Emissions from Shipping: The Need for Regulation and Approaches to Compliance

Shipping has traditionally been viewed as the least environmentally damaging mode of freight transport. Recent studies have increasingly questioned this perception, as attention has focused on both the greenhouse gas emissions (mainly CO₂) and the emission of health-damaging pollutants (such as sulphur, nitrogen oxides and particulates) by ships. This paper reviews the available evidence on the atmospheric emissions of shipping. It proposes that the profit objective has prompted the pursuit of greater fuel efficiency within the sector, but that reliance on market forces alone is insufficient to deliver on the environmental imperative. The paper outlines the current and planned regulatory regime for the atmospheric emissions from ships and posits that greater, and more diverse, market regulation is required. Alternative general approaches to regulatory compliance are categorised as ‘alternative sources of energy’ or ‘abatement technologies’ and the characteristics of a range of specific options are analysed. The paper concludes that although the shipping industry has been slow to improve its environmental credentials, a combination of regulation and technological innovation provides it with significant potential to dramatically reduce its environmental impact.     

Designing a decision support model for the LNG market

Abstract

As the Liquefied Natural Gas (LNG) market is supply-driven and subject to long-term contracts, both liquefaction companies and shipowners need to make strategic decisions on fleet chartering requirements. These planning decisions become ever more difficult in light of the transformations permeating the LNG market, propelling into a more competitive market with more flexible trades and expanding spot markets. The overcapacity of LNG ships during 2008–2009 triggered by massive overcontracting is a good case in point where the use of decision support models would have been beneficial, especially considering the fortunes and risks at stake. In this paper we present an LNG shipping model that effectively supports decision-making in practice. To demonstrate the value added of the model, we study the implications of LNG project delays and increased decommissioning of ships with respect to market balance and fleet requirements.
