【摘要】：随着全球经济的飞速发展,各国之间贸易往来日益频繁,船舶已经成为国际间货物运输的主要交通工具,与船舶运输相关的港口航道、码头等各配套设施的安全性已经成为航运界研究的重点。目前,航运领域的众多专家学者针对港口航道通航安全的综合评价方法进行了广泛的探讨与研究,也都取得了良好的评价结果。但我们应该看到,每种方法都有各自的优势与不足。本文尝试采用新方法建立综合评价体系,对港口航道通航安全进行综合评价,为后续研究提供新思路。本文首先通过查阅国内外针对综合安全评价所做的方法研究,得到目前安全评价领域评价方法的研究现状,在此基础上深入探究集对分析与粗糙集理论的内容,并将其与前人成功运用的综合评价方法进行对比,以体现集对分析与粗糙集客观性强、理论直观、应用简洁等优势,并将两者有机结合,建立集对分析—粗糙集综合评价模型,以具体问题验证模型的可行性与适用性。针对港口航道系统的特性,基于前人的研究成果得到影响港口安全的所有主要因素。本文将港口航道作为一个系统进行综合考虑,将影响航道通航安全的环境因素、船舶因素、人为因素进行全面分析,得到最终所需的评价指标。接着将集对分析—粗糙集综合评价模型应用到航口通航安全评价中,其步骤为：利用粗糙集理论的区分矩阵对评价指标进行筛选,得到影响航道安全性的最重要指标,并利用粗糙集中的属性重要度思想确定指标权重,随后用集对分析评价机理通过处理后的指标对港口航道进行安全评价,得到最终评价结果。最后,本文以青岛港主航道为例,收集相关数据,运用集对分析和粗糙集理论对数据进行分析处理,得出青岛港主航道的安全等级,通过实例对本文建立的集对分析—粗糙集综合评价模型进行验证,以证明其适用性。
[Abstract]:With the rapid development of the global economy, trade between countries is becoming more and more frequent. Ships have become the main means of transport of international cargo, the port and waterway related to ship transport. The safety of various supporting facilities, such as wharves, has become the focus of research in the shipping industry. At present, many experts and scholars in the shipping field have carried out extensive discussions and studies on the comprehensive evaluation methods for the navigation safety of ports and waterways. But we should see that each method has its own advantages and disadvantages. This paper attempts to establish a comprehensive evaluation system by using new methods to evaluate the navigation safety of the port and waterway. To provide a new idea for the follow-up study. First of all, by referring to the domestic and foreign methods of comprehensive safety assessment, the present research status of safety evaluation methods in the field of safety evaluation is obtained, and on this basis, the content of set pair analysis and rough set theory is deeply explored. In order to reflect the advantages of set pair analysis and rough set analysis, the theory is intuitionistic and the application is simple, the comprehensive evaluation model of set pair analysis and rough set is established by combining the two methods. The feasibility and applicability of the model are verified by specific problems. According to the characteristics of the port channel system and based on the previous research results, all the main factors affecting the port safety are obtained. In this paper, the comprehensive consideration of the port channel as a system will affect the environmental factors of the navigation safety. The ship factor and human factor are analyzed comprehensively, and the final evaluation index is obtained. Then, the set pair analysis and rough set comprehensive evaluation model are applied to the evaluation of navigable safety at the port. The steps are as follows: using the distinction matrix of rough set theory to screen the evaluation index to obtain the most important index affecting the channel safety, and using the attribute importance of rough set to determine the index weight. Then the mechanism of set pair analysis and evaluation is used to evaluate the safety of the port and waterway through the treated indexes, and the final evaluation results are obtained. Finally, taking the main channel of Qingdao Port as an example, this paper collects relevant data, analyzes and processes the data by using set pair analysis and rough set theory, and obtains the safety grade of the main waterway of Qingdao Port. The set pair analysis-rough set comprehensive evaluation model established in this paper is verified by an example to prove its applicability.
