基于动态规划算法的集装箱码头集卡优化调度模型

集卡是非自动化集装箱码头重要的水平运输设备,其作用是实现集装箱在码头前沿与堆场间的水平位移。集卡调度通常是根据岸吊作业顺序进行的。优化集卡调度能减少岸吊等待时间,提高码头装卸效率。目前国内外已有许多学者对集装箱码头装卸过程中的集卡分配和调度问题进行研究:BISH等[1]运用启发式算法建立基于车辆的集卡分配模型,从而使船舶在港时间最短;     

基于无人集卡的自动化集装箱码头仿真研究

随着汽车自动驾驶技术与港口应用场景的深度融合,自动化集装箱码头装卸工艺系统方案呈现多样性。本文依托无人集卡运输方式,通过建立自动化集装箱码头装卸工艺系统仿真模型,结合码头相关运营模块,从岸桥装卸效率、集卡运输能力、码头整体交通流和闸口通过能力等四个方面进行仿真,以验证装卸工艺方案的合理性。     

基于多智能体仿真的集装箱港口作业效率研究

集装箱港口生产作业系统是复杂的离散事件系统,数学建模方法难以构建针对整个系统的模型,而基于过程的仿真模型通常缺乏对设备调度的灵活性。为准确描述我国集装箱港口的作业流程,分析内卡配置数量对港口作业效率的影响,提出了基于事件驱动的集装箱港口多智能体(Multi-Agent)仿真模型。仿真结果表明:岸桥平均装卸效率(GCR)随着内卡数量的增加先急剧增加后缓慢增加,船舶平均等待时间(AWT)和平均在泊时间(AST)与岸桥平均装卸效率呈明显负相关关系。     

集装箱码头安全管理实践——以上海浦东国际集装箱码头为例

1集装箱码头作业特点(1)作业机械化现代集装箱码头的岸边装卸、水平搬运、堆场进提箱等作业均已全面实现机械化。通过岸桥、轮胎吊、集卡、正面吊等专用设备,集装箱码头可实现快速、高效、连续作业。通常情况下,3000~4000TEU集装箱船舶最快可在靠泊码头后的24h内完成装卸作业,装卸效率远远高于传统散货船的装卸效率。     

集装箱岸桥智能化防拖系统

集装箱码头作业中,吊具与集卡的交互过程是装卸作业的重点环节,也是事故高发区段,主要是易在交互过程未完成时集卡即启动运行,拖拽吊具造成设备和人员损伤。设计了一种集装箱岸桥智能化防拖系统,实现在交互过程中自动进行集卡锁定,预防误操作可能造成的事故,提高集装箱码头作业的安全性和效率。

集装箱码头物流路径优化研究

根据集装箱码头的工艺流程,提出了集装箱码头物流路径优化模型。该模型以集卡行走里程最短为目标,在满足集装箱堆场堆存要求和船舶装卸作业要求的情况下,求解集卡最优行走路径。算例计算表明,该优化模型可为码头管理者提供一定决策帮助。     

自动化岸边集装箱起重机模拟操作系统设计

作为码头前沿的关键装卸设备,岸边集装箱起重机(以下简称"岸桥")的装卸效率在一定程度上决定着集装箱码头的装卸效率.随着自动化集装箱码头建设在世界各地蓬勃兴起,自动化岸桥广泛应用于新建自动化集装箱码头.自动化岸桥应用于新建码头可能存在以下问题:一是岸桥司机和设备工程师对自动化岸桥不熟悉,需要实操培训后才能上岗,从而在无形中导致码头运营成本上升;二是自动化岸桥作业采用远程操作模式,不正确的操作流程和方法不仅会降低码头作业效率,而且存在极大的安全隐患.为了避免在应用自动化岸桥的过程中出现上述问题,鹿特丹港MV2自动化集装箱码头、丹吉尔港TM2自动化集装箱码头、上海港洋山深水港区四期自动化集装箱码头等均向岸桥设备生产商采购自动化岸桥模拟操作系统.

Recent progress on wave induced loading measurements in warships

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.
