摘　　要：直达列车多点装卸取送顺序直接关系到铁路货车运用效率和列车运行线的良好接续 ,因而采用优化的取送顺序有利于提高铁路经济效益 .现行方案优化方法计算工作量大 ,在作业地点较多时难以实现 .提出了直达列车多点装卸取送顺序优化的数学模型 ,论述了表上移动法解算该数学模型的原理及方法 ,为取送顺序方案优化提供了直观、简捷 ,可以迅速得到最优方案的新途径 .Car group sending and fetching schedule for through trains distributed to several loading or unloading places is related directly to the car economic efficiency and the coordination of the train paths, so it is important to adopt an optimized car group sending and fetching schedule. But in order to select the best scheme a huge quantity of calculation should be fulfilled and it is even difficult when the number of the loading or unloading places is large using the traditional algorithm. Therefore the method should be improved. In this paper the mathematical model for optimization of car group sending and fetching schedules is put foreward for through trains, the principles and the method to resolve the model by moving the sending and fetching order on table are explained at some length which would be concise and intuitional, and the answer could be gotten quickly and easily in this way.
