单OD对间集装箱多式联运最优路径选择研究

随着世界经济全球化和区域经济一体化的不断进步,特别是跨国公司的高速发展,国际贸易日趋频繁,极大地推动了集装箱多式联运的发展。为有效降低运输成本、减少不必要的运力浪费,提升集装箱运输效率,从集装箱多式联运的经济性角度出发,分析集装箱多式联运路径选择的影响因素及其相互关系,构建基于Petri网的运输径路优化模型,并以单OD对间集装箱多式联运为例,利用Petri网、库所中托肯概率密度等工具,以总成本最小为目标函数,确定最优的联运路径,从而达到节约人力、物力资源的目的,为实际的生产运输提供参考性建议。

A Research on the Optimal Path Selection between Single OD Pairs for Multi-modal Container Transportation

With the continuous progress of world economic globalization and regional economic integration, especially the rapid development of multi-national companies, international trade has become increasingly frequent, greatly promoting the development of container multi-modal transportation. To effectively reduce transportation costs as well as unnecessary waste of transportation capacity, and improve the efficiency of container transportation, this paper focuses on the analysis of the influencing factors and their mutual relations in the selection of container multi-modal transportation routes from the economic point of view of multi-modal container transportation. This paper establishes a Petri net-based transportation route optimization model,and takes the single OD pair multi-modal transportation as an example, using tools such as Petri net and TOKEN probability density in warehouse, the optimal path selection strategy for container multimodal transport between single OD pairs is determined with minimizing the total cost as the objective function, so as to save manpower and material resources and provide reference suggestions for actual production and transportation.
