货物作业车取送模型的优化

Optimization of Freight Cars°φ Placing-in and Taking-out Model

合理确定取送车作业顺序,有利于减少货车在站非生产时间,加速车辆周转。运用图论中的哈密尔顿图,建立取送及装卸作业的数学模型,从整体取送车作业过程来分析,将树枝型专用线的取送车问题,转化为寻求哈密尔顿图回路机车作业时间最短方案的最优问题。

Good operation order of car’ placing-in and taking-out is advantageous to reduce nonproductive time of freight cars at station and accelerate vehicles circulation. By adopting Hamilton Graph, the paper builds up a mathematical model for wagons’ placing-in and taking-out and goods loading & unloading operation. Taking into consideration of the whole placing-in and taking-out process, the paper turns the problem of wagons' placing-in and taking-out on branch-shaped sidings into the problem of seeking optimized plan for shortest operation time of locomotives on Hamilton Graph.
