考虑箱流中转的高速铁路快捷货物运输方案优化
Optimization of Express Freight Transportation Plan with High Speed Railway Considering the Box Flow Transfer
摘要
Abstract
In order to make full use of the transport capacity and spillover effect of high speed railway trunk lines,this paper adopted the piggyback mode of high speed railway passenger EMUs,guided by the time-varying demand of box flows.The aim is to optimize the demand allocation for express delivery boxes while considering the transfer of such boxes.Based on the existing train timetable,this paper constrcuted an optimization model for the transport plan after establishing the train connection matrix.The model aimed to minimize the total travel time for express boxes,while accounting for constraints such as box flow conservation,train carrying capacity,and express box transfers.This paper designed a simulated annealing algorithm based on the characteristics of the model.Following the generation of an initial solution,a feasible algorithm was designed with the core purpose of resolving conflicts related to train capacity contraints.Finally,the effectiveness of the model and algorithms was further verified through numerical experiments,using the Nanjing-Hangzhou high speed railway as an illustrative example.The results show that the transportation plan derived from this model can eliminate express box delays and increase the average train load rate by 14%compared with the model that does not consider the transfer of express boxes.In addition,the reasonable estimation of train load capacity is important to obtain the optimal transport plan.关键词
