Abstract

In the modern logistics environment, effective cargo packing and stowage strategies are crucial to improving transportation efficiency and meeting customer needs. Improving cargo loading efficiency will help increase transportation capacity and reduce transportation costs. Freight EMUs are limited by the current small number of trains running, and domestic research on loading optimization of freight EMUs is insufficient. Therefore, in-depth research on cargo packing and stowage optimization methods in freight train units to improve transportation efficiency, reduce costs, and meet the needs of cargo transportation to the greatest extent has become an important plan for popularizing freight train units. This article first discusses the transportation characteristics of freight train units, reviews the current research status of cargo packing and stowage optimization at home and abroad, and summarizes various methods and algorithms used in existing research. Based on the analysis of the advantages and disadvantages of these methods, a useful reference is provided for this study. In view of the particularity of freight train unit transportation, through the idea of staged optimization, we discuss the constraints and optimization objectives for cargo loading containers and box car loading respectively, establish mathematical models for each, and use genetic algorithms, simulated annealing algorithms, and search trees etc., realized the optimization of cargo packing and container stowage in the EMU. Finally, through actual case analysis, the effectiveness and feasibility of the proposed method were verified, and improvement plans and prospects were proposed accordingly.
