Path Selection for Fresh Products Multimodal Transportation with the Participation of High-Speed Rail Express
摘要
Abstract
To enhance the transportation efficiency and quality of fresh products,this paper incorporates high-speed rail express services into a multimodal transportation system for fresh products.Considering the distinctive transportation characteristics of fresh products and the limitations imposed by mixed time windows,a path selection model has been developed to minimize overall costs while simultaneously maximizing customer satisfaction.Furthermore,to solve this model,an improved non-dominated sorting genetic algorithm with elite selection strategy is employed.Finally,this paper validate the feasibility and effectiveness of both the model and algorithm using 11 hub cities along with 3 modes of transportation:road,high-speed rail,and air freight.Sensitivity analysis are conducted based on different multimodal transportation modes,node time windows,cargo volumes,and delivery deadlines.The simulation results indicate that the improved algorithm demonstrates superior performance in addressing multimodal path selection problems;additionally,the road-high-speed rail multimodal mode exhibits advantages in terms of both total cost and customer satisfaction for fresh product transportation.It is also observed that constraints related to node time windows increase overall transportation costs and influence path selection decisions.Therefore,it is essential to balance considerations regarding cargo volume and delivery deadlines to achieve optimal economic benefits alongside enhanced customer satisfaction.关键词
