【摘要】：近年来,世界经济的回暖带动了航运业的发展,国家对港口的未来目标提出了诸多要求,特别是要进一步完善沿海港口的布局,提升优化港口码头,满足大型船舶的服务需求。港口的高速发展带来了可观的经济效益,同时也对港口系统的运营和维护提出了更高的挑战,不仅要增加泊位数量的增加,提高通过能力,更需要保持通航安全和拓展专业高效的服务功能。如何对现有的航道资源进行利用,如何更加准确的评估通过能力,这是港口部门亟需解决的问题。为应对不断增多的交通量和频发的安全事故,本文探讨了航运安全的主要影响因素,建立航道多指标评价体系,确定各因素的影响程度,并将其作为模型搭建的基础。采用模糊逻辑理论,构建航运安全评估模型。依托隶属度函数和逻辑语句进行建模,考虑交通量、航道宽度、能见度和航道深度等四个因素,并通过计算分析,重点研究交通量与安全等级之间的联系。本文分析港口航道作业系统,通过对港口航道系统的仿真建模,选取年通过船舶量、年通过货物量和服务水平三个指标,将安全因素作为约束条件来研究通过能力。本文主要考虑航运安全、单双航道、排队规则和港口的规模之间的关系,基于仿真结果,探讨不同因素对于通过能力的影响程度,为港口部门的航道管理提供理论支持,具有一定的现实意义。
[Abstract]:In recent years, the warming of the world economy has led to the development of the shipping industry. The state has put forward many requirements for the future objectives of the port, especially to further improve the layout of the coastal ports and to upgrade and optimize the port terminals. The rapid development of the port has brought considerable economic benefits. At the same time, it has also posed a higher challenge to the operation and maintenance of the port system, not only to increase the number of berths, but also to improve the capacity of passage. It is also necessary to maintain navigation safety and expand professional and efficient service functions. How to make use of the existing waterway resources, how to evaluate the passing capacity more accurately, In order to deal with the increasing traffic volume and frequent safety accidents, this paper discusses the main influencing factors of shipping safety, establishes the waterway multi-index evaluation system, and determines the influence degree of each factor. The model is based on fuzzy logic theory, which is based on membership function and logic statement, considering four factors, such as traffic volume, channel width, visibility and channel depth. Through calculation and analysis, the relationship between traffic volume and safety grade is studied emphatically. This paper analyzes the port channel operation system, through the simulation modeling of the port channel system, selects the annual ship volume. In this paper, the relationship between shipping safety, single and double channels, queuing rules and port size is considered, based on the simulation results. It is of practical significance to explore the influence of different factors on the capacity of the port and to provide theoretical support for the waterway management of the port department.
