【摘要】：交通运输是社会和经济发展的先决条件和重要保障,对促进区域间资源的合理配置和社会分工起到重要作用。湖北省地处长江中游,九省通衢,是我国中部地区重要的交通运输节点。优越的地理位置和良好的经济发展势头为长江干线湖北段综合货物运输通道的建设和发展创造了得天独厚的条件和稳定的货源,而随之引发的更为迫切的货物运输需求也对长江干线湖北段综合货运通道的进一步建设和完善提出了更高的要求。针对综合货物运输通道内不同种运输方式的情况进行准确评价与定位,既是提高综合运输体系效率的重要手段,也是对运输网络进行合理规划的有力保证。本文首先介绍了综合运输通道的内涵及类型,并对目前综合运输评价研究中选用的评价方法及其存在的不足进行了分析。其次,分析了长江干线湖北段综合货运通道的基础设施和运营情况,并指出了目前综合货运通道建设存在的问题。在建立评价模型时,先从货主企业、运输企业和政府部门三个角度阐述了综合货运通道评价的必要性,在经过对多种评价方法进行比较以后,选择了基于离散突变-模糊物元法的评价模型。在实证分析部分,结合长江干线湖北段综合货物运输通道的特性,选定铁路、公路及水路三种运输方式作为研究对象,从经济、技术、社会和可持续发展四个方面建立了多层次货物运输通道评价体系,并对定性和定量指标分别进行了评分和计算。针对现有运输方式评价存在的模糊性及不确定性,以及传统定权方法在客观性与准确性上的不足,本文采用模糊物元法对评价体系内各指标数据进行处理,并引入离散系数法计算各评价指标的权重。然后根据评价体系的结构和各评价指标的相对重要性与逻辑关系,并结合之前得到的权重数据,用突变评价法对模糊物元评价法得出的计算结果进行优化处理,计算出各种运输方式的贴近度,从而完成对各种运输方式的评价。根据贴近度的计算结果,运用1ogit模型计算出综合货运通道内三种运输方式的分担率。最后根据模型的评价结果,提出相应的综合货运通道协同发展的建设策略。
[Abstract]:Transportation is the prerequisite and important guarantee for the development of society and economy. It plays an important role in promoting the rational allocation of resources and the social division of labor. Hubei province is located in the middle reaches of the Yangtze River and the thoroughfare of the nine provinces. It is an important transportation node in the central region of China. The superior geographical position and good economic development trend are the Yangtze River main line Lake The construction and development of the northern section of the comprehensive cargo transport channel has created a unique and stable source of goods, and the more urgent demand for freight transport has also raised a higher requirement for the further construction and improvement of the Hubei section of the Yangtze River trunk line. Accurate evaluation and location are both important means to improve the efficiency of integrated transportation system, and also a powerful guarantee for reasonable planning of transportation network.
This paper first introduces the connotation and types of comprehensive transport channel, and analyzes the evaluation methods and shortcomings in the comprehensive transportation evaluation research. Secondly, it analyzes the infrastructure and operation of the comprehensive freight channel in the Hubei section of the Yangtze River, and points out the existing problems in the construction of the comprehensive freight channel. In the establishment of evaluation model, the necessity of comprehensive freight channel evaluation is expounded from three angles of cargo owners, transportation enterprises and government departments. After comparing a variety of evaluation methods, the evaluation model based on discrete catastrophe fuzzy matter element method is selected. In the empirical analysis part, combined with the Hubei section of the Yangtze River, the comprehensive goods are combined. The characteristics of the transport channel are selected as the research object of the three modes of transportation, such as railway, highway and waterway. From the four aspects of economy, technology, society and sustainable development, the multi-level transportation channel evaluation system has been established, and the qualitative and quantitative indexes are evaluated and calculated respectively.
In view of the fuzziness and uncertainty existing in the evaluation of existing modes of transportation, and the shortcomings of the objectivity and accuracy of the traditional method of weight determination, the fuzzy matter element method is used to deal with the index data in the evaluation system, and the weight weight of each evaluation index is calculated by the discrete coefficient method. Then, the structure of the evaluation system and the evaluation of the evaluation system are also evaluated. The relative importance of the index and the logical relation, combined with the weight data obtained before, with the mutation evaluation method to optimize the calculation results obtained by the fuzzy matter-element evaluation method, and calculate the close degree of various transportation modes, so as to complete the evaluation of various modes of transportation. The 1ogit model is used to calculate the result of the calculation of the root according to the close degree. Finally, according to the evaluation results of the model, the corresponding strategies for the coordinated development of the integrated freight corridor are put forward based on the evaluation results of the three models.
