铁路同类适盘货物装载方案优化研究

Optimization of railway pallet-suited freight loading scheme

结合铁路货物装载约束条件,构建了使用托盘的同类长方体货物铁路货车装载优化模型,首先提出了改进二维布局优化算法求解托盘在车厢底面的布局方式,再确定托盘货件在车厢内的最佳堆码层数,得到货物的装车优化方案。实例分析结果表明,该算法是一种求解铁路同类适盘货物装载问题的有效方法。

We construct an optimization model for similar rectangular freights loaded freight trains with pallets based on railway freight loading constraints. We initially solve pallets layout of carriage bottom with improved two-dimensional layout optimization algorithm. We further determine optimal stacking pallet layers in a carriage, and obtain optimal loading scheme. Instance analytical results show that the model is effective for solving railway similar pallet applied freight loading problem.
