考虑腹地关系的内河港口竞争策略分析

针对上下游两个内河港口之间的竞争问题，考虑相邻港口同时选择单一定价、单一定价-差别定价、差别定价-单一定价和差别定价4 种竞争策略情形下，运用Hotelling 博弈方法，在考虑港口之间水运成本的情况下，对不同竞争阶段港口的均衡价格、市场份额和利润进行了比较. 研究表明：港口的均衡结果与两港的位置和水上、陆路单位运费率之比有关；只有单一港口选择差别定价时，其可以获取更高的市场份额和利润；分别以不同阶段的市场份额、利润作为支付函数，上下游港口的纳什均衡均为差别定价策略.     

Assessing greenhouse gas emissions from port vessel operations at the Port of Incheon

This paper measures greenhouse gas emissions from port vessel operations by considering the case of Korea’s Port of Incheon. It provides estimates of greenhouse gas emissions based on the type and the movement of a vessel from the moment of its arrival, to its docking, cargo handling, and departure. Taking a bottom-up approach based on individual vessels’ characteristics and using data on vessels processed by the port in 2012 estimate emissions. The results indicate that the level of emissions is five times higher than that estimated through the top-down approach. Among various types of vessels, international car ferries are the heaviest emitters, followed by full container vessels and car carriers. A vessel’s passage through lock gates and maneuver to approach the dock accounts for 96% of its emissions. Docking for cargo handling shows the lowest level of GHG emissions.     

集装箱港区后方陆域规划研究

随着集装箱港口吞吐量的快速增长以及港口海关监管模式改革在全国范围内的开展，特别是海关大通关和区港联动试点工作的顺利进行，使得集装箱港区后方陆域表现出了明显的不适应港口发展需求的态势。文章从影响港口发展因素入手，就港区后方陆域配用空间中的各功能区进行了分析，重点对后方陆域规划中的集疏港交通网络规划建设进行了研究。     

屏蔽双绞线抗电磁干扰研究及其在城轨车辆上的应用

针对城轨车辆上不同设备和子系统之间的电磁兼容问题,分析了用于设备和子系统互连的屏蔽双绞线的抗电磁干扰机理,并利用广义二端口网络,建立双绞线串扰简化模型。对屏蔽层不同端接方式进行了测试,并对测试数据进行分析,为屏蔽层合理接地提供了依据。最后给出了一个屏蔽双绞线应用于城轨车辆的实例。     

A simulation model for gate operations in multi-purpose cargo terminals

ABSTRACT

A multi-purpose cargo terminal in a seaport contains necessary infrastructure to handle different types of cargo, such as container, dry bulk, general bulk, and Ro-Ro. Since such terminals generally have dedicated areas and equipment for different types of cargo, berth, and yard operations for each type of cargo can be considered separate. On the other hand, trucks that carry all types of cargo use the same gate structure to enter and leave the terminal. Therefore, a method to superimpose the traffic that is caused by different types of cargo is needed for the planning of gate investments and operations. Consequently, this paper has developed a simulation model for a multi-purpose terminal to estimate the gate traffic and determine the necessary gate infrastructure, so that it can be used as a decision support tool for terminal planners and operational managers.     

Passengers’ Perceived Service Quality of City Buses in Taipei: Scale Development and Measurement

Abstract

To understand fully passengers’ perceptions and expectations of the bus service quality in Taipei, business managers and governmental agencies must seek a proper scale that can reflect passengers’ opinions accurately. This study develops and tests a service quality scale designed for a city bus transit system in Taipei. Churchill’s paradigm and a focus group interview were combined into a multistage scale development procedure. Based on the procedure, Taipei city buses were selected as the example, for which a service quality scale was developed. The final scale contains four dimensions and 20 items. These four dimensions are ‘interaction with passengers’, ‘tangible service equipment’, ‘convenience of service’ and ‘operating management support’. Finally, the results of scale development and the managerial applications of the service quality scale for the city transit system are discussed.

现代绿色物流系统的建设要求物流链上各环节按照绿色理念建设运营.本文将绿色物流的思想引入内陆港选址问题,建立了考虑噪声、事故、拥挤、碳排放等环境因素的广义费用函数,并根据内陆港建设决策方与货主之间的主从递阶决策关系,构建了可兼顾投资者与货主对成本要求的内陆港双层规划选址模型.模型上层目标为在允许的投资范围内确定内陆港地址,使得系统总成本最小;下层目标为货主在各内陆港之间分配运输需求量,使得总支出费用最低.并设计了基于遗传算法的求解方法.实例分析表明,本文建立的绿色理念下的内陆港双层规划选址模型是有效的,同时遗传算法可以产生稳定的最优解.

江苏港口高质量发展现状评价

为明确江苏港口高质量发展的环境条件与阻碍因素,采用数据分析法对江苏港口的发展现状进行综合分析,结果表明,江苏港口的传统优势较大,但仍处于粗放型发展阶段。构建了港口高质量发展评价指标体系,并采用R型因子模型法进行实证分析,结果表明,江苏港口除了在集装箱港口作业效率、集装箱在港作业成本、港口运作能力等个别指标上有较优表现外,其余大多指标均远落后于标杆港口。实证分析为江苏港口高质量发展指出了方向。
