1集装箱码头堆场管理的重要性
集装箱码头堆场管理是指在堆场总体安排原则指导下,以确保码头正常作业为前提、提高码头作业效率为目标的一系列堆场策划工作。它是码头生产作业的一个重要环节,主要包括集装箱的交接(进提箱)、堆场整理以及装卸船等有关的堆场策划安排。 相似文献

集装箱码头堆场作业系数是堆场作业量与船舶装卸作业量之间的比例。该系数是反映堆场计划管理水平高低的主要指标之一,系数越高,堆场内无效作业越多,堆场作业成本越高,效率越低;因此,如何降低堆场作业系数已成为集装箱码头企业的重点研究课题。本文分析集装箱码头堆场作业系数影响因素,提出优化堆场作业系数的方法和措施,以便码头根据自身实际情况将堆场作业系数控制在科学、合理的水平。 相似文献

堆场作业效率是体现自动化集装箱码头海侧装卸船能力、陆侧收发箱水平的重要指标。针对自动化集装箱码头堆场作业过程中出现的堆场调度工况不合理、效率较低的问题,进行堆场调度规则研究。通过对堆场各工况实际作业需求进行分析,确立堆场海侧、陆侧作业调度原则,优化不同工况调度顺序,增加自动化堆场作业重进重出比例,改善自动化码头堆场调度逻辑,并对比调度规则优化前后的堆场作业效率。结果表明,优化后的堆场调度规则可以显著提升自动化码头堆场作业效率和对外服务水平,提高自动化码头核心竞争力。 相似文献

堆场计划管理在集装箱码头中的应用 总被引:2,自引:0,他引:2
集装箱码头生产计划主要有堆场计划、配载计划与船舶计划等三大块,堆场计划作为其中一项,具有重要的作用。 码头堆场是水陆集装箱的集散中转地,是码头的作业前沿,堆场管理是码头生产的重要环节。堆场管理合理与否极大地关系到码头装卸速度、码头堆场利用率、码头通过能力与码头生产成本。 堆场计划管理主要涉及进出口箱的堆存计划、进出场管理、移箱管理、进场时间管理和中控室指挥管理,面广点多。过去其一直是码头生产管理的薄弱环节,存在很多不规范的做法,给码头实现现代化管理带来很多障碍。因此。只有有效地改善堆场计划管理,完… 相似文献

正随着我国集装箱航运市场的快速发展,集装箱码头对堆场装卸效率的要求越来越高,而堆场的翻箱作业直接影响堆场的发箱速度和码头作业的整体流畅性;因此,降低集装箱码头堆场翻箱率是提高堆场作业效率、降低码头运营成本的关键,对提高港口竞争力有重要意义。本文以泉州港石湖港区(以下简称石湖港区)为例,分析产生堆场翻箱的原因,并提出降低内贸进口重箱堆场翻箱率的对策,以期为提升集装箱码头堆场服务质量提供参考。 相似文献

Container transportation plays a critical role in the global shipping network and container terminals need to improve their operations to increase efficiency. Storage yard of a container terminal is a temporary area where the containers stay until they are shipped to their next destination. We concentrate on increasing the efficiency of the storage yard by developing online stacking policies for each incoming container. An unproductive move of a container, performed to reach another container stored underneath, is called reshuffling. The objective in container stacking problem is to minimise the number of reshuffles, thereby increasing the efficiency of terminal operations. Additional weight-related operational constraints bring additional complexity to the online stacking decisions. We propose a mathematical model for the optimal online assignment of an incoming export, transit, import or empty container. We also propose an optimal online stacking policy and compare it with a random policy through simulation. Additionally, lower bounds for the performance measures are obtained through simulation by relaxing the operational constraints of the problem in a third stacking policy. We present and discuss the computational results in terms of four main performance measures. 相似文献

The impact of higher container stacking on yard operations has been treated as one of the major factors influencing the efficiency of terminal operations. For terminal operators who have to increase their storage capacity by way of higher container stacking, the consequences must be carefully measured. This paper examines the unproductive container movements undertaken in one high throughput terminal with high land productivity, and provides an example of how terminal operator handles the yard operations and the possible impact on areas of operation. 相似文献
