Train Work Plan Formulation for Wagonload Freight Based on Double-Layer Dynamic Space-Time Network
摘要
Abstract
With the adjustment of industrial structure,studying the core technologies for organizing wagonload freight transportation to complete transportation of goods with high added value has great significance for guiding railway transportation production.This paper abstracted the train work plan formulation problem as a double-layer dynamic space-time service network design problem.By considering the actual production of railway transportation,the optimization objectives of minimizing the cost of train transportation,train operation,and non-transportation penalty were set.The paper analyzed constraints such as flow conservation,train formulation,and transfer operation time,constructed a model for the train work plan formulation for wagonload freight based on the double-layer dynamic space-time network,and designed an artificial bee colony algorithm to solve the model.The model and algorithm were verified by constructed cases based on the information of the actual railway network and train working diagram.The results show that the algorithm can effectively simulate two key links in the train work plan,which are the car flow combination and the train path selection.The model provides relevant assistance and decision support for the efficient formulation of the train work plan.It is of great practical significance for improving the organization efficiency of wagonload freight transportation.关键词
