台山核电厂重要厂用水系统纳潮取水口潮流及泥沙研究

文章研究了台山核电厂重要厂用水系统纳潮取水工程。根据实测资料分析了自然条件和岸滩演变。分别建立了工程海区二维波浪、潮流、泥沙数学模型,并根据实测资料对夏季和冬季全潮水文进行了验证。在经验证的数学模型基础上,研究了重要厂用水系统纳潮取水工程实施后的潮流变化及泥沙回淤情况。结果表明,重要厂用水系统纳潮取水工程实施后,流场变化仅局限于安全取水工程附近小范围海域,进水前池附近水域泥沙年冲淤和骤淤都不大。因此,从潮流、泥沙角度考虑,重要厂用水系统纳潮取水工程是可行的。     

基于B/S的船舶机务管理系统公共数据服务平台设计

为了改善传统船舶机务管理系统成本高、维护难、效率低的现状及适应当前计算机技术的迅速发展,采用云计算和Web技术,建立基于B/S架构的机务管理系统公共数据服务平台,采用模块化设计思想,在传统机务管理系统的基础上增加权限管理和能源管理模块,不仅提高了机务管理系统的可维护性、可扩展性、易开发性和安全性,也提高了船员的工作效率和船舶的适航能力.     

内河船舶交通流建模与仿真研究

为了更精确地模拟内河船舶交通流的运行状态,根据内河船舶相互影响特性,将航道作为交通流中为船舶提供通航服务的主要资源,将船舶行为及相互之间的耦合关系模型化,在此基础上构建基于通航服务资源的内河船舶交通流模型.利用仿真软件进行仿真实验,结合长江干线某断面流量数据进行实例验证.实验结果表明,该模型能较好地模拟内河宏观交通流.     

公务艇技术经济性评价指标分析及论证

根据公务艇的自身特性,参照GB11697—89的相关规定,建立了一套适用于公务艇技术经济性能分析的评价指标体系和计算方法。实践证明：此评价指标体系可对公务艇的技术经济性进行有效分析,并评估其是否达到目标要求,便于指导今后的设计工作;同时,此评价指标体系也是对有关船舶与海洋结构物性能水平等级评价体系国家标准的有益补充。

Advances in port studies: the contribution of 40 years Maritime Policy & Management

Port economics, management and policy have progressively emerged as a distinctive research field, and a core part of maritime economics. This paper provides an analysis of all the 267 port studies published in Maritime Policy & Management (MPM) since its inception in 1973. This paper provides a content analysis for seven interrelated research theme categories including main research topics and methods, authorship distribution and citation counts. It is demonstrated that MPM played, and continues to play, a key role in publishing research on seaports. The published research increasingly applies established analytical frameworks to ports. The paper concludes with a discussion on current challenges for port-related research.     

现行荷载规范船舶排水量和受风面积的曲线拟合

对港口工程荷载规范2010版中75%保证率下的船舶排水量和受风面积进行了曲线拟合,计算结果与规范计算结 果基本一致,表明了所提出的拟合曲线适用于不同船型的船舶排水量和受风面积计算,为规范中未包括的船型排水量和受 风面积的计算提供了一个更趋于合理、简便、精确的新方法。     

Regulation,trust and contractual incentives around transport contracts – Is there anything bus operators can learn from public air service contracts?

This paper compares recent experiences in contract negotiation and subsequent commitment in public air services with the bus industry. The heart of the paper is a survey of European and Australian regional airlines, which we mirror with revealed experiences of bus operators. We aim to identify a number of elements in the contracting regimes that have exposed ambiguity and significant gaps in what the principal (e.g., transport department) expected, and what the agent (airline or bus operator) believed they were obliged to deliver. Ultimately airline and bus services are similar in that public authorities procure transport services that are desirable for the society but would be unprofitable without government involvement. In both sectors (theoretically fairly similar) public transport contracts are used, and those usually include obligations and performance measurements. In terms of similarities, one of the surveyed contract details that had a perceived high clarity in both industries was “payment procedures” and amongst those with rather poor clarity was also in both industries “incentives to improve performance and grow patronage”. We also show differences between regional air services and bus operations with regard to performance measurement and pre-specified obligations. Because of the strong safety culture around air services we find that regulation and trusting partnerships are even more important to aviation than to the bus sector. Because of the high level of trust but also because of simpler and more complete contracts in aviation, there is much less (re-)negotiation going on compared to the bus operations.     

Evaluating the service requirements of dedicated container terminals: a revised IPA model with fuzzy AHP

The purpose of this article is to evaluate the service requirements of dedicated container terminals (DCTs). In this article, the service attributes (SAs) of DCTs were first discussed. A fuzzy analytic hierarchy process model was then constructed to measure the users’ perceived importance and dissatisfaction for each of the SAs. Based on these two measurements, a revised importance-performance analysis model was proposed to identify the SAs that should be improved. To validate the model, the dedicated container terminal of Evergreen Marine Corp. (EMC DCT) at Kaohsiung Port and its users were empirically investigated. With respect to the empirical results, managerial implications of the findings in improving service quality for the EMC DCT are discussed.
