【摘要】：内陆集装箱多式联运是连接国际集装箱多式联运和内陆城市的重要环节,研究内陆集装箱多式联运的货流分配,以实现费用的节约和时间的节省,对于实现城市间合理的货物流向和社会综合经济效益都具有重要的意义。为了争夺更多的货源,港口之间的竞争也越来越激烈,面对这种无序竞争的局面,港口可以选择适当的合作。近年来,随着博弈论被大家广泛地熟知,对于博弈论的研究也越来越多,特别是对于合作博弈的研究,甚至一些国际上经济发展速度较快的国家试图研究将博弈论用在经济领域。所以将博弈论应用在集装箱多式联运货流分配上具有很重要的现实意义。针对各港口间激烈的货流竞争,本文阐述了港口腹地对港口间竞争的影响,从多次博弈的角度,分析说明了港口间采取适当合作的可能性。通过比较三类合作博弈的分配方法,即夏普利值法、核心法和核仁法,验证了夏普利值法用于货流分配的优越性。在此基础上,从定性的角度分析了港口自身条件对其吸引腹地货流的影响,依据各因素对吸引力的影响程度,提出了港口间货流分配的方法：在夏普利值中,考虑了合作博弈下影响港口间货流分配的因素,引入了投入因子、贡献因子、地位因子和风险因子四个关键因子,确定了四个关键因子的权重,修正了货流分配的系数,以此对夏普利值法进行了改进。结合改进的夏普利值法,通过考虑各节点的操作能力、各运输方式的运力约束,构建了以运输全过程总成本最小为目标的货流分配优化模型。通过算例验证与分析,得出了各种运输方式的货流量,及其在总货流量中所占的比重,算例结果证明了改进的夏普利值法用于港口间货流分配的合理性,能为集装箱多式联运货流分配提供决策参考。
[Abstract]:Inland container multimodal transport is an important link between international container multimodal transport and inland cities. The distribution of inland container multimodal transport is studied in order to realize cost saving and time saving.It is of great significance to realize the reasonable flow of goods between cities and the comprehensive economic benefits of society.In order to compete for more goods, the competition between ports is becoming more and more fierce. In the face of this kind of disorderly competition, the port can choose appropriate cooperation.In recent years, as game theory is widely known, there are more and more researches on game theory, especially on cooperative game theory.Even some countries with fast economic development have tried to apply game theory to the economic field.Therefore, the application of game theory in container multimodal cargo flow distribution has very important practical significance.In view of the fierce cargo flow competition among ports, this paper expounds the influence of port hinterland on port competition, and analyzes the possibility of appropriate cooperation between ports from the point of view of multiple games.By comparing the distribution methods of three kinds of cooperative game, I. e., Sharpley value method, core method and kernel method, the superiority of Sharpley value method in the distribution of cargo flow is verified.On this basis, from the qualitative point of view, the paper analyzes the influence of port's own conditions on the attraction of cargo flows in hinterland. According to the degree of influence of various factors on the attraction, the method of distribution of cargo flows between ports is put forward: in the Sharpley value,Considering the factors that affect the distribution of cargo flow between ports under cooperative game, the paper introduces four key factors: input factor, contribution factor, status factor and risk factor, determines the weight of four key factors, and modifies the coefficient of cargo flow distribution.In this way, the Sharpley value method is improved.Combined with the improved Sharpley value method, considering the operation capacity of each node and the capacity constraints of each transportation mode, a freight flow allocation optimization model with the goal of minimizing the total cost of the whole transportation process is constructed.Through the example verification and analysis, the cargo flow of various transportation modes and its proportion in the total cargo flow are obtained. The result of the example proves the rationality of the improved Sharpley value method in the distribution of cargo flow between ports.It can provide decision-making reference for container multimodal cargo flow distribution.
