【摘要】：近年来全球物流运输业的迅猛发展,更是给港口物流业带来了前所未有的机遇和挑战。考虑到运输过程中市场多样化的需求、码头吞吐量的不断增长以及保证码头物流生产运营系统高效率的运转等等因素，结合世界物流运输的发展趋势,在今后一段时期内,我国港口码头建设如能采用兼备集装箱和件杂货作业的综合码头则将是比较经济和现实的途径。面对日益增长的港口货物吞吐量,如何对港口物流系统进行更加合理有效的规划,以最大限度地发挥其作业能力,是目前急需解决的问题,开展这方面的研究势在必行,具有重大意义。本文以Em-plant软件为仿真平台，重庆港某综合码头为实例对其物流系统进行深入的仿真分析,使得本课题的研究具有理论及实际价值。论文主要工作包括以下内容：（1）阐述了课题研究的背景和意义，系统分析了国内外有关港口物流系统建模仿真技术的研究现状，并明确了本文主要研究内容。（2）研究分析了综合码头的基本组成，码头特征及布置原则、码头的进出口作业流程，在此基础上对其装卸工艺系统以及码头物流系统交通流量来源进行了分析，最后阐述了码头的物流系统性能评价指标的含义。（3）阐述了Em-plant软件的特点、仿真中软件提供的基本建模单元，，仿真建模步骤，并重点研究分析了码头仿真建模中的仿真策略以及码头随机事件变量，为其物流系统仿真分析做好了充分的理论准备。（4）以某综合码头为实例，结合码头的相关实际参数和仿真目标的要求，在Em-plant仿真环境下对它仿真建模，模型中对码头设施设备合理地简化，通过对装卸船、集疏运、堆场道路、性能统计参数四个主要模块仿真的实现，模拟了码头船舶到港靠泊、岸桥装卸船作业、集卡水平运输以及堆场作业的动态过程，仿真输出了码头吞吐量、泊位利用率、船舶在港停留总时间、港口主要干道交通流量等码头性能评价指标的值，最后基于仿真模型对码头物流系统中的岸桥设备配置、集卡调度策略等关键问题进行了研究，通过数据分析得出结论。
[Abstract]:In recent years, the rapid development of the global logistics industry has brought unprecedented opportunities and challenges to the port logistics industry. Considering the diversified demand of the market in the course of transportation, the increasing throughput of the terminals and the efficient operation of the logistics production and operation system of the wharf, and taking into account the development trend of the world logistics transportation, and in the coming period, It will be an economical and practical way to construct the port wharf in our country if it can adopt the integrated wharf with both container and groceries. Facing the increasing port cargo throughput, how to plan the port logistics system more reasonably and effectively so as to give full play to its operational capability is a problem urgently needed to be solved at present. It is imperative to carry out the research in this field. Of great significance. In this paper, the em-plant software is used as the simulation platform, and an example of Chongqing port is used to simulate and analyze the logistics system, which makes the research of this subject have theoretical and practical value. The main work of this paper is as follows: (1) the background and significance of the research are described, and the research status of modeling and simulation technology of port logistics system is analyzed systematically. The main research contents of this paper are defined. (2) the basic composition, the characteristics and layout principles of the integrated wharf, the operation flow of import and export of the wharf are studied and analyzed. On the basis of this, the paper analyzes the loading and unloading process system and the traffic flow source of the terminal logistics system. Finally, the meaning of the evaluation index of the logistics system performance of the wharf is expounded. (3) the characteristics of the Em-plant software are expounded. The basic modeling unit provided by the software, the simulation modeling steps, and the simulation strategy and random event variables of the wharf simulation are studied and analyzed. The simulation and analysis of the logistics system is well prepared. (4) taking a comprehensive wharf as an example, combining with the actual parameters of the wharf and the requirements of the simulation target, the simulation model is established under the em-plant simulation environment. In the model, the facilities of the wharf are reasonably simplified. Through the simulation of the four main modules of loading and unloading ship, collecting and distributing road, stacking yard road and performance statistics parameter, the dock ship berthing and loading and unloading operation on the shore bridge are simulated. The dynamic process of collecting card horizontal transportation and yard operation is simulated and outputted the terminal throughput, berth utilization ratio, the total stay time of the ship in port, the traffic flow of the main trunk roads of the port, and so on. Finally, based on the simulation model, the paper studies the key problems such as the equipment configuration of the quayside bridge and the card collection scheduling strategy in the logistics system of the wharf, and draws a conclusion through the analysis of the data.
