【摘要】：随着各行各业对集装箱运输这种方式的认识不断加深,“方便、快捷、安全、高效”的特点获得更多客户的认可,集装箱运输产业链蓬勃发展,其中专业化集装箱码头数量、规模迅速扩大。但随着全球经济形势发展持续低迷和国内大气候的变化,近几年各港口受市场化的发展须求,也为了生存,集装箱码头之间的竞争日渐激烈。为了控制集装箱运输的营运成本,各班轮公司也不得不考虑减少集装箱船周转时间,控制船舶在港作业时间来降低运作成本、提升运作效率。为提高码头综合实力、吸引更多船舶到港,集装箱码头正逐步改变经营管理策略,从传统的仅仅依靠提高码头固定资产投资、建新泊位、投新设备、加大资源配置创高效率等粗放外延生产增长方式,向优化装卸作业流程、优化码头物流系统内部资源配置等精细化内涵式生产增长方式转变。泊位—岸桥是整个码头装卸作业系统的关键环节和瓶颈。在泊位数量、作业岸桥数、码头前方堆场规模等有限的资源条件下,对船舶进行有效的泊位配置,能有效缩短船舶等待时间。本文通过了解集装箱码头的基本业务流程,构建了集装箱码头装卸系统优化的原则及关键影响因素,确定了集装箱码头装卸系统优化的运作流程,并结合新时代集装箱码头的实际情况,构建了以船舶总作业时间最短为目标的数学模型,采用遗传算法对其进行求解,并最终提出保障其协调运作的保障措施。
[Abstract]:With the deepening understanding of container transportation in various industries, the characteristics of "convenience, quickness, safety and efficiency" have been recognized by more customers, and the industrial chain of container transportation has developed vigorously, including the number of specialized container terminals. The scale is expanding rapidly. However, with the development of global economic situation and the change of domestic climate, in recent years, the development of various ports must be market-oriented, but also in order to survive, the competition between container terminals is becoming increasingly fierce. In order to control the operating cost of container transportation, the liner companies also have to consider reducing the turnaround time of container ships, controlling the working time of ships in Hong Kong to reduce the operating costs and improve the operational efficiency. In order to improve the comprehensive strength of the wharf and attract more ships to port, the container terminal is gradually changing its management strategy, from the traditional only relying on the increase of fixed assets investment, construction of new berths, new equipment, Increase resource allocation, create high efficiency and other extensive extension production growth mode, to optimize loading and unloading operation flow, optimize the internal resource allocation of logistics system of wharf, etc. Berth-shore bridge is the key link and bottleneck of the terminal loading and unloading system. Under the condition of limited resources such as the number of berths, the number of operating quayside bridges and the scale of yard in front of the wharf, the effective berth allocation of the ship can effectively shorten the waiting time of the ship. Through understanding the basic business process of container terminal, this paper constructs the principle of container terminal loading and unloading system optimization and key influencing factors, and determines the operation process of container terminal loading and unloading system optimization. Combined with the actual situation of the container terminal in the new era, a mathematical model aiming at the shortest total operation time of the ship is constructed, and the genetic algorithm is used to solve it. Finally, the guarantee measures to ensure the coordinated operation of the container terminal are put forward.
