【摘要】：交通运输是我国经济的基础产业,在国民社会经济发展中发挥了基础性、保障性和先导性的重要作用,进一步发展高效、协调的综合运输体系,是交通运输产业发展的必然趋势。运输通道是国家、地区交通运输系统的骨架和大动脉,承担着不同地区间运输联系的大部分或全部运输任务,运输通道交通资源配置的合理与否对于综合运输体系的建立至关重要。目前我国的运输通道正在飞速发展,但在通道资源消耗方面的理论研究还十分薄弱,没有形成完成的理论体系,难以指导通道的规划、建设和运营管理,所以系统全面的研究通道资源消耗构成、通道资源消耗与运输效率之间的互动关系、通道运输资源的优化配置等一系列重大问题,建立相应的研究框架和理论体系,对运输通道的规划、建设和运营管理具有重要的理论价值及实践指导意义。本文正是在此背景下,试图探索运输通道资源消耗与运输效率之间的关系,进而从运输效率的角度对通道的资源消耗进行测算和优化配置。文章首先在对大量相关文献进行总结的基础上,回顾了交通资源消耗测算及优化配置等相关研究成果,介绍了交通资源的界定、特性、配置途径,确定了运输效率的量化指标,重点分析了运输效率与通道资源消耗的关系;其次,详细剖析了单运输方式资源消耗构成和费用特性,把其资源消耗分为固定成本和变动成本两部分,将从其开始建设到废弃全过程的建设、运营、维护、人工、时耗、能耗、环境污染、交通事故等成本纳入目标函数,搭建了单运输方式全寿命周期的资源消耗测算模型,进而求得单位周转量运输通道系统成本计算公式;然后,重点研究两种交通方式组合的运输通道单位周转量系统成本,以通道单位周转量系统成本最小作为目标函数值,构建通道交通方式组合的资源消耗优化模型并提出相应的求解算法;最后,为了检验本文中通道资源优化配置理论方法的正确性和可行性,依据文中的理论方法体系,选取一个在我国具有代表性的运输通道进行实证研究分析,检验了该方法的科学性和可行性,为综合运输通道的建设及优化提供理论指导与技术支持。
[Abstract]:Transportation is the basic industry of our economy, which has played an important role in the development of national society and economy, and further developed an efficient and coordinated comprehensive transportation system. It is the inevitable trend of the development of transportation industry. Transport passageway is the skeleton and major artery of national and regional transportation system, which is responsible for most or all transportation tasks of transportation links between different regions. It is very important to set up a comprehensive transportation system for the rational allocation of transportation resources in transport passageways. At present, the transportation channel in our country is developing rapidly, but the theoretical research on the consumption of channel resources is still very weak, there is no complete theoretical system, and it is difficult to guide the planning, construction and operation management of the passage. Therefore, a series of important issues, such as the composition of channel resource consumption, the interaction between channel resource consumption and transport efficiency, the optimal allocation of channel transport resources, and so on, are studied systematically and comprehensively, and the corresponding research framework and theoretical system are established. It has important theoretical value and practical guiding significance to the planning, construction and operation management of transportation passage. Under this background, this paper attempts to explore the relationship between transport channel resource consumption and transport efficiency, and then calculates and optimizes the resource consumption of transport channel from the point of view of transport efficiency. On the basis of summarizing a large number of related literatures, this paper reviews the related research results such as calculation and optimization of traffic resource consumption, introduces the definition, characteristics and allocation approach of traffic resources, and determines the quantitative index of transportation efficiency. The relationship between transport efficiency and channel resource consumption is analyzed in detail. Secondly, the structure and cost characteristics of resource consumption in single mode of transportation are analyzed in detail, and the resource consumption is divided into two parts: fixed cost and variable cost. The whole process of construction, operation, maintenance, labor and time consumption will be completed from its beginning to abandonment. The cost of energy consumption, environmental pollution and traffic accidents is included in the objective function, and the calculation model of resource consumption in the whole life cycle of single mode of transportation is built, and then the calculation formula of the system cost of transportation channel per unit turnover is obtained. Then, the paper focuses on the study of the system cost of the unit turnover of the two combined modes of transportation, taking the minimum cost of the system of the unit turnover of the channel as the value of the objective function. The resource consumption optimization model of channel traffic mode combination is constructed and the corresponding solution algorithm is put forward. Finally, in order to verify the correctness and feasibility of the theoretical method of optimal allocation of channel resources in this paper, according to the theoretical method system in this paper, a representative transport channel in China is selected for empirical research and analysis. The method is proved to be scientific and feasible, which provides theoretical guidance and technical support for the construction and optimization of integrated transportation channel.
