Abstract
In order to reduce the terminal distribution cost of high speed rail express in the city and improve the efficiency of distribution,this paper studied the path planning of terminal distribution of high speed rail express in a"distribution center-free"mode from the perspective of"the last mile"of high speed rail express.Considering the constraints of high speed railway operation time,vehicle line capacity,and distribution time and taking the total transportation cost and time as the target,this paper constructed the optimization model of the terminal distribution path of high speed rail express and designed an improved genetic algorithm to solve it.With the high speed rail express in Shanghai station as an example,through the comparison of three algorithms,it is verified that the improved genetic algorithm has a better convergence effect and better solution performance.The results based on the improved algorithm show that the organic connection between high speed rail express and terminal distribution in cities can provide fast and accurate distribution services.Through the analysis of different truck load capacities,the best distribution scheme is obtained,which provides relevant guidance and decision support for the terminal distribution path planning of high speed rail express.关键词
