【摘要】：当前，贵州省航运业正处于重要发展时期，乌江航道与枢纽通航设施的建设为区域经济发展提供了极大助力。随着沿江经济的快速发展以及乌江航运条件的大改善，乌江航运将翻开新的篇章，到2020年乌江年货运量将达到1500万t。然而，乌江梯级开发后，现有船舶货运组织方式单一低效以及枢纽通航设施通过能力不统一且不足等问题将与未来日益增长的运输需求极为不适应。为有效解决以上问题，提高通航设施的通过效率，实现乌江航运与经济的大发展，优化乌江船舶货运组织方式及船型已迫在眉睫。从未来的运输缺口分析可见，单一采用过枢纽运输组织方式，无法解决通过能力不足的问题，而建设乌江新通道的条件也尚不具备，翻坝运输将势在必行。本文首先对常规翻坝货运组织方式进行了综合分析；从提高乌江运能出发，提出将船上皮带运输作为乌江翻坝新型货运组织方式之一，选择自卸船作为该种货运组织方式下的翻坝专用船型。乌江目前还没有自卸船，作为乌江翻坝新型货运系统的关键要素，其船型主尺度论证至关重要，可为科学指导市场，促进乌江船型标准化奠定技术基础。为此本文重点围绕乌江自卸船船型论证展开研究工作。乌江自卸船作为一种新船型，有其特定的通航环境和船型特点。目前常用船型论证方法有层次分析法、模糊综合评判方法、主成分分析方法、灰关联度分析方法和DEA方法等。但现有船型论证方法在权重系数确定、评价指标相关性和论证结果信息量方面各有不足之处，为此本文提出一种改进DEA方法，，不仅能够解决主客观权重系数确定方法在权重系数确定过程中产生的不利影响，同时论证结果可以反馈更多的信息，为船型方案提出改进方向，并为船型论证方法的研究提供新思路。本文通过引入具体算例，分别采用改进DEA方法和层次分析法以及DEA方法进行船型对比论证，验证了该方法的可行性；并基于对自卸船船型特点和技术关键的分析，构建乌江自卸船综合评价指标体系；采用网络法结合改进DEA方法对乌江自卸船进行论证分析，最终得到乌江自卸船各载货吨级最优船型方案，经实例应用，验证了该方法的有效性。
[Abstract]:At present, Guizhou's shipping industry is in an important period of development. The construction of Wujiang waterway and navigation facilities provides a great help for the development of regional economy. With the rapid development of the economy along the Yangtze River and the great improvement of the shipping conditions along the Wujiang River, the shipping of the Wujiang River will open a new chapter, and the annual cargo volume of the Wujiang River will reach 15 million tons by 2020. However, after the development of Wujiang cascade, the problems of single and low efficiency of ship freight organization mode and the inconsistency and insufficiency of navigation facilities passing through the hub will be extremely unsuitable for the increasing transportation demand in the future. In order to solve the above problems effectively, improve the efficiency of navigation facilities and realize the great development of shipping and economy in Wujiang, it is urgent to optimize the organization and type of shipping in Wujiang. It can be seen from the analysis of the transportation gap in the future that it is impossible to solve the problem of insufficient passing capacity by adopting the single transportation organization mode of the hub, and the conditions for the construction of the new channel of Wujiang River are not yet available, so it will be imperative to carry over the dam. In this paper, a comprehensive analysis is carried out on the conventional freight transportation mode, and from the point of view of improving the transportation capacity of Wujiang River, it is put forward that the transportation of belt on board is one of the new types of freight transportation organization in Wujiang River. The self-unloading ship is chosen as the special ship type of overturning dam under this kind of freight organization mode. At present, Wujiang has not unloaded its ship. As the key element of the new type of freight system, the demonstration of the main scale of the ship type is very important, which can lay a technical foundation for guiding the market scientifically and promoting the standardization of Wujiang ship type. Therefore, this paper focuses on the Wujiang self-unloading ship type argumentation. As a new type of ship, Wujiang dump ship has its special navigable environment and characteristics. At present, the methods of ship type argumentation include Analytic hierarchy process, Fuzzy Comprehensive Evaluation, Principal component Analysis, Grey Relational degree Analysis and DEA, etc. However, the existing ship type demonstration methods have their shortcomings in the determination of weight coefficient, the correlation of evaluation indexes and the amount of information on the results of demonstration. Therefore, an improved DEA method is proposed in this paper. It can not only solve the adverse influence of subjective and objective weight coefficient determination method in the process of weight coefficient determination, but also can feedback more information from the result of demonstration, and propose the improvement direction for the ship type scheme. It also provides a new idea for the study of ship type demonstration method. In this paper, the feasibility of this method is verified by introducing concrete examples, adopting the improved DEA method, the analytic hierarchy process method and the DEA method, respectively, and based on the analysis of the characteristics and technical key points of the self-unloading ship, the feasibility of the method is verified. This paper constructs the comprehensive evaluation index system of Wujiang self-unloading ship, uses the network method combined with the improved DEA method to demonstrate and analyze the Wujiang self-unloading ship, and finally obtains the optimal ship form scheme for each cargo tonnage class of the Wujiang self-unloading ship, which is applied by an example. The effectiveness of the method is verified.
