Discussion on the Logistics Construction of Railway Container Freight Stations

From the perspective of logistics, the article discusses some essential functions and service functions of railway container freight stations. Then it plans the construction of the logistics operation system of container freight stations, and designs five main operating yards such as deconsolidation and groupage yard, storage and distribution yard, container receiving-departure yard, container stack yard, and special cargo yard. The management pattern is discussed under the direction of modern business management theory. The ideas presented in this article is significant to the construction of railway container freight stations.     

Heuristic estimation of container stacking and reshuffling operations under the containership delay factor and mega-ship challenge

This paper addresses a highly researched area, the reshuffling problem in ports, using a new paradigm-modified containership service order in light of credit risk assessment. Container stacking and reshuffling operations can cause ship delays and additional risk. In deep-sea terminals, outbound containers are tightly stacked according to the retrieval sequence. Due to lack of space, terminals stack containers in multiple tiers. This means any delay in the arrival of a ship can impose extra handlings and reshuffling of containers delaying future cargo handling. This paper addresses the reshuffling problem with a concept similar to the credit scoring and rating of creditworthiness used in the banking industry. By utilizing this comparison to the banking credit risk concept, a heuristic estimation model is proposed that illustrates the side effects of unscheduled modifications in containership service order. Further, the mega-ship trend amplifies the reshuffling debate. Probability of delay, reshuffles given delay, and call size at delay are introduced as the three-point risk metrics of the model. Numerical simulations illustrate the functionality to develop terminal stacking strategies as well as emphasize the mega-ship phenomenon and its side effects on terminals (i.e. yard operation deadlock).     

Cranes scheduling in frame bridges based automated container terminals

This paper investigates crane scheduling problems for a new type of automated container terminal system, which is based on multi-storey frame bridges. For the new design concept, this paper studies how to schedule two types of cranes, i.e., quay cranes and bridge cranes that transfer containers between different storeys. The schedules of these two types of cranes impact the operation efficiency of the terminal system. Mathematical models are proposed for the two scheduling problems. Meta-heuristics are developed to solve them. Numerical experiments are conducted to validate the effectiveness of the proposed models and the efficiency of the proposed solution method.

基于仿真技术的集装箱海港港内锚地设置对航道通过能力的影响

通过分析沿海集装箱港区单向航道船舶进出港作业流程,提出航道资源有限时可通过建设港内锚地以提高航道通过能力的思路。基于计算机仿真技术,建立拥有港内锚地的沿海集装箱港区船舶航行作业系统仿真模型,研究港内锚地的锚位数对航道通过能力的影响。仿真结果表明:港内锚地锚位数与航道通过能力服从多项式的函数关系,且存在极值;在该极值范围内,建设港内锚地对提高航道通过能力效果显著,但当锚位数超过极值后航道通过能力将不再随锚位数的增加而增加;因而该极值可为确定港内锚地的建设容量提供参考。     

对中小城市总体规划中交通强制性内容的思考——以青海省平安县为例

通过分析城市总体规划的编制要求和存在的问题,研究城市总体规划中交通强制性内容的编制落实问题。对于中小城市而言,大城市市域轨道交通延伸线不宜作为中小城市总体规划的强制性内容,线路选线应以次干路和非骨架性主干路为主,所经道路红线宽度不小于40 m;城市总体规划文本不必将次干路及以上等级道路全部作为强制性内容,而应选择其中的骨干道路网络;交通枢纽布局的关键在于枢纽用地控制,客运交通枢纽用地可以根据客运交通枢纽构成按照＂分别计算、各项求和＂的方法进行估算,货运交通枢纽用地可以结合物流仓储用地、铁路和公路货运场站用地进行估算。最后,以青海省平安县城市总体规划为例进行说明。     

铁路综合客运枢纽静态导向标志版面设计方法

由于铁路综合客运枢纽静态导向标志系统设计缺乏相关规范、标准和指导方法,其标志版面设计存在不统一、系统性差等问题。首先对枢纽内旅客行为特性进行分析,总结旅客的视觉和认知特性,采用视频调查法调查分析旅客在公共换乘区和站台区域自由流状态下的步行速度分布特征。基于标志颜色理论、现有标志规范、文字字高计算模型以及国内外标志应用情况和研究成果,从标志版面的颜色、图形、文字、形状及布局5个方面展开探讨,提出铁路综合客运枢纽静态导向标志版面设计方法。     

广州市轨道交通枢纽用地开发模式研究

如何确定城市轨道交通枢纽的开发模式以获取最大的效益已成为对其进行合理开发需要探讨的重要课题。首先指出广州市现有轨道交通枢纽用地规划及开发模式不佳,缺乏明确的开发导向。在明确轨道交通枢纽范围和分类的基础上,分析居住、商业、办公三类用地在吸引客流、服务时间、土地增值方面的特性,提出广州市各类轨道交通枢纽用地开发的主导功能。同时,通过建立轨道交通枢纽用地开发投资平衡模型,给出广州市轨道交通枢纽用地开发强度建议。最后,从规划设计流程、建设模式、开发机制三方面提出后续研究方向。
