考虑班次差异影响下的东南亚中欧班列路径优化
Route Optimization of China Railway Express in Southeast Asia Considering Effect of Schedule Differences
摘要
Abstract
As the China-Laos-Thailand international freight train is put into service,the transportation and logistics system of China Railway Express is continuously improved,which provides new ideas for freight transportation in Southeast Asia.To explore the importance of transportation schedules in route optimization,this research was conducted from the perspective of multimodal transport operators.By considering the differences in the types of China Railway Express during actual transportation,the effect of different transportation schedules on transportation costs and time was analyzed.A dual-objective function for transportation costs and time was established based on transportation schedules,and the non-dominated sorting genetic algorithm II(NSGA-II)was used to solve the Pareto solution set.The analysis results of 15 transportation routes show that there are significant differences in transportation costs and time when freight is transported through the same nodes but with different schedules.In addition,due to the different preferences of freight transportation for transportation costs and time,different weight coefficients were set to analyze the optimal route,thereby providing a reference for transport operators to choose the optimal transportation plan.关键词
