港口集装箱吞吐量的不平衡性

港口生产的不平衡性是港口规模、货源组织、车船运行、社会习惯、自然条件及生产管理等诸多因素综合作用的结果,隐含着与港口生产相关的多种信息,对港口码头的通过能力有较大影Ⅱ向。相关码头设计规范中用港口生产的不平衡系数衡量港口生产的不平衡性,定义港口生产不平衡系数为在一年内港口月最大货运量与港口月平均货运量的比值。本文根据相关统计数据,用港口月吞吐量与年内港口月平均吞吐量的比值（下称月不平衡性比值）分析考察国内外港口集装箱吞吐量的不平衡性。     

港口发展集装箱物流服务的优势和途径

现代物流发展水平是一个国家综合国力发展水平的重要标志之一,港口现代物流发展水平则是我国港口城市综合竞争力发展水平的重要指标之一,而集装箱物流服务水平是物流现代化的重要标志。改革开放以来,我国持续增长的国民经济带动港口集装箱运输快速发展,近年来,集装箱年吞吐量跃居世界第1。同时,我国集装箱运输呈现强劲的增长势头：2005年,我国港口集装箱吞吐量排名前10的港口的增长速度均在15％以上,其中,宁波港增长速度高达30．2％：内河长江主要港口之一的芜湖港集装箱运输量以年均33％的速度持续增长。我国集装箱运输迎来黄金时代,集装箱物流服务已成为港口跨越发展的强力助推器。如何使更多的港口从传统装卸彻底向现代物流转型,并促进港口跨越发展,已成为业界的热门话题。     

遗传算法在港口集装箱装卸顺序中的应用

船舶在执行航运作业时,集装箱的排放序列及配载管理是影响集装箱物流效率的关键因素之一。合理的集装箱放置规划可以减少船舶停港时的倒箱作业,充分利用龙门吊作业时序分配,提高航运物流效率。船舶港口集装箱装卸顺序本质是一个NP模型,模型复杂性与集装箱种类及停靠码头数量有关。遗传算法是NP模型重要解决方案,本文在研究了现代船舶港口集装箱装卸模型的基础上,设计了基于遗传算法的解决方案,极大提高了装卸效率。     

Optimal investment priority in container port development

The aim of this paper is to develop realistic and relevant investment planning models for inland container transportation systems. The models may be utilized to identify the most effective investment plan for inland transportation infrastructure development and to evaluate the inland container transportation system. The procedure enables determination of the optimal locations, sizes and time of container port developments as well as the optimal container cargo flows through transportation networks. A heuristic algorithm was developed for the purpose of evaluating alternative investment plans. Dynamic and linear programming methods are applied to each of the two planning problems: the former for the optimum container port capacity development problem and the latter for the optimal allocation of inland container traffic movements. The model has been applied to concrete inland container transportation system problems in Korea.

Determinants of container port choice in Spain

For the economic and financial evaluation of port investment projects, it is important to know the demand function of a port's services. The objective of this study is to establish such a demand choice function for the Spanish container port services. The function is derived from the coefficients of a port choice model, for which a multinomial logit model is used and of which the coefficients are estimated with regression analysis. The variables tested concern inland transport cost, ocean transport costs and broad proxy variables for quality of service. Information on container import and export flows for 2007 is obtained from the Spanish Treasury Department. The linear regression analysis is based on differences of utilities of alternative routings of containerised cargoes compared to those routed via the port of Valencia. The obtained results are satisfactory in terms of model fit. The estimated coefficients can be used to assess the impact of changes in costs of container flows routed via a port on a port's market share. A demand choice function for the port can be derived by systematically doing so. An example is presented for the port of Valencia.
