【摘要】：随着世界经济的不断发展,全球贸易量的不断增加,集装箱贸易量也会持续增加,集装箱港口已经在全球贸易中成为不可或缺的一员。然而,集装箱港口的作业效率是制约港口运作成本的一项关键因素,为了满足船公司在港时间的要求,港口不能通过一味的增加设备的拥有量来实现,这样会极大的增加港口的投资成本,因此,为了满足船公司的在港时间要求,同时也为了降低港口的运作成本,对进口集装箱卸载设备资源的集成调度模型研究就显得尤为重要。本文在对国内外进口集装箱卸载设备资源调度现状和集成调度现状进行分析的基础上,明确了进口集装箱卸载设备资源集成调度的意义与目标,并确定了本文的研究方法和思路。在对影响进口集装箱卸载设备资源集成调度的因素进行分析的基础上,建立集成调度的概念模型,之后运用仿真软件Arena建立了进口集装箱卸载设备资源的集成调度仿真模型,运用该模型对集装箱港口一个调度期内将要到达的船舶进行了仿真运行,并运用数学模型对运行结果进行了评价与分析,之后利用OptQuest寻找到一组最优解,得出进口集装箱卸载设备资源集成调度的方案,即在满足船舶预计离港时间的范围内,使用最少的资源配置,使得港口的卸载成本尽量小。本文的创新点主要体现在如下三个方面:(1)本文建立了以港口集装箱卸载成本最小的资源集成调度模型,利用Arena软件仿真计算得到了最佳资源调度组合方式,并且对调度模型中的关键参数如单个岸吊服务的最少集装箱数,单个岸吊需要配备的集卡数量,调度期内开放的场吊数量等进行优化,同时利用软件还可以对设备资源总数如码头岸吊数量,码头集卡数量等进行优化,优化参数之多在以往的研究中尚未出现。(2)本文建立的集装箱设备资源集成调度模型中,考虑了卸载过程中资源的实时重新调度分配。即当码头出现空闲岸吊时,可以将其分配给已经开始卸载的船舶,从而提高卸载效率,这点在以往的仿真研究中并未涉及。(3)本文构建的仿真模型除可以用以分析码头最优集装箱最佳资源调度组合方式及资源配置外,还可以针对一个调度期内船舶到达实际情况,自动生成最优具体调度方案,节省了方案生成需要的时间成本及人力成本。
[Abstract]:With the development of the world economy and the increasing of the global trade volume, the container trade volume will continue to increase. Container port has become an indispensable member in the global trade.However, the efficiency of container port operation is one of the key factors that restrict the port operation cost. In order to meet the requirements of shipping company's time in port, the port can not be realized by blindly increasing the quantity of equipment.This will greatly increase the investment cost of the port. Therefore, in order to meet the requirements of the shipping company for the time spent in port, and also to reduce the operating cost of the port,It is particularly important to study the integrated scheduling model of the unload equipment resources for imported containers.On the basis of analyzing the present situation of resource scheduling and integrated scheduling of imported container unloading equipment at home and abroad, this paper clarifies the significance and goal of resource integration scheduling of imported container unloading equipment.The research method and train of thought of this paper are determined.Based on the analysis of the factors that affect the integrated scheduling of imported container unloading equipment resources, the conceptual model of integrated scheduling is established, and then the integrated scheduling simulation model of imported container unloading equipment resources is established by using the simulation software Arena.The model is used to simulate the ship that will arrive in a dispatch period of container port, and the mathematical model is used to evaluate and analyze the operation result. After that, a set of optimal solutions are found by using OptQuest.The scheme of integrated resource scheduling of imported container unloading equipment is obtained, that is, within the range of the expected departure time of the ship, the least resource allocation is used, which makes the unloading cost of port as small as possible.The innovation of this paper is mainly embodied in the following three aspects: 1) this paper establishes a resource integrated scheduling model with the minimum unloading cost of port container, and uses Arena software to simulate and calculate the optimal resource scheduling combination mode.And the key parameters in the dispatching model such as the minimum number of containers for single shore crane service, the number of collecting cards needed for single shore crane, the number of open field hoists during the dispatching period are optimized.At the same time, the software can be used to optimize the total equipment resources, such as the quantity of terminal shore crane, the quantity of wharf collecting card, and so on. The optimization parameters have not appeared in the previous research. 2) in the integrated dispatching model of container equipment resources established in this paper,The realtime rescheduling and allocation of resources in the process of unloading is considered.That is, when there is a free shore hoist at the wharf, it can be allocated to ships that have already begun unloading, thus improving the unloading efficiency.This point is not involved in the previous simulation research.) the simulation model constructed in this paper can be used not only to analyze the optimal container resource combination mode and resource allocation, but also to deal with the actual situation of ship arrival in a scheduling period.The optimal scheduling scheme is generated automatically, which saves the time cost and labor cost.
