【摘要】：复杂性研究是本世纪系统科学发展的方向,复杂系统往往由大量的元素组成,具有非线性、动态性、不确定性以及不断演化的特征,是一类非平衡的开放体系。现代大型专业集装箱码头物流系统就是这样一个复杂系统,存在许多工程技术难题。查阅学科前沿文献可知,过去几乎没有学者从现代复杂系统科学的思想系统地研究集装箱码头物流系统的复杂性问题,本论文的研究工作可为深入系统地研究和解决集装箱码头物流系统的复杂性问题奠定一定的学术基础,也是添补集装箱码头物流系统研究的一个学术空白,主要做了以下几个方面的研究： (1)集装箱码头物流系统复杂性的定性分析。描述集装箱码头物流系统的组成、动态行为与状态变量以及动态流程与反馈控制。分析码头环境作用、规模与平面布置形式以及生产组织和实施过程中的复杂性,包括生产信息输入、车辆与船舶输入、天气影响、码头泊位数、不同的平面布置结构以及装卸船和集疏运运作过程等因素对码头复杂性的影响。 (2)从宏观、中观、微观三方面分析集装箱码头物流系统复杂性特征,然后从平面布置的不同形式分析复杂性的来源,从集装箱种类复杂性、结构复杂性以及过程复杂性三个方面论述了其静态复杂性的具体影响因素。 (3)基于系统信息熵的基本理论,明确了集装箱码头物流系统复杂度的基本含义,建立了集装箱码头物流系统局部与整体结构复杂度的计算模型,可综合评价码头局部与整体的复杂度,比如,可用于计算堆场不同分块数的结构复杂度,评价堆场的平面布置方案,其值越大,表明物流系统越复杂。 (4)以码头路网结构为对象,基于信息熵理论提出了码头路网结构复杂性测度的计算方法。通过计算路网节点的复杂度,可分析比较各路网交叉口的复杂度,寻求道路节点复杂度的优化分布；通过对码头整体路网结构复杂性的计算,可比较不同码头设计方案的路网结构的优劣,进行方案评选。 论文在现代复杂系统科学思想的引领下,对集装箱码头物流系统复杂性进行了深入的研究,为提高集装箱码头规划设计水平拓展了理论分析空间,所取得的研究成果具有较重要的学术价值和工程意义。
[Abstract]:Complexity research is the development direction of systems science in this century. Complex systems are often composed of a large number of elements, with the characteristics of nonlinearity, dynamics, uncertainty and continuous evolution. Complex systems are a class of non-equilibrium open systems. Modern large-scale specialized container terminal logistics system is such a complex system, there are many engineering technical problems. According to the frontier literature of the subject, in the past, few scholars systematically studied the complexity of container terminal logistics system from the modern complex system science. The research work of this paper can lay a certain academic foundation for further and systematic research and solution of the complexity of container terminal logistics system, and it is also an academic blank in the research of container terminal logistics system. The main research is as follows: (1) qualitative analysis of the complexity of container terminal logistics system. Describes the composition of container terminal logistics system, dynamic behavior and state variables, dynamic process and feedback control. Analysis of the environmental role, scale and layout of the wharf, as well as the complexity of production organization and implementation, including production information input, vehicle and ship input, weather impact, berth number, The influence of different layout structure, loading and unloading ship and collecting and distributing operation process on the complexity of the terminal. (2) the complexity characteristics of container terminal logistics system are analyzed from macro, meso and micro aspects. Then analyze the source of complexity from the different forms of layout, from the complexity of container types, Three aspects of structural complexity and process complexity are discussed. (3) based on the basic theory of system information entropy, the basic meaning of the complexity of container terminal logistics system is defined. A computational model of the local and overall structural complexity of the container terminal logistics system is established, which can be used to evaluate the local and global complexity of the terminal. For example, it can be used to calculate the structural complexity of different blocks of the yard. The larger the value of the layout of the yard is, the more complex the logistics system is. (4) based on the information entropy theory, a calculation method of the complexity measure of the terminal road network structure is proposed based on the information entropy theory. By calculating the complexity of road network nodes, the complexity of road network intersections can be analyzed and compared, and the optimal distribution of road node complexity can be found. The network structure of different wharf design schemes can be compared and evaluated. Under the guidance of the scientific thought of modern complex system, this paper makes a deep research on the complexity of container terminal logistics system, and expands the theoretical analysis space for improving the level of container terminal planning and design. The research results obtained have important academic value and engineering significance.
