本文首先简要介绍重载运输在我国开行的现状 ,在此基础上建立一个重载列车去向模型。引进一个先进的算法——遗传算法求解模型 ,根据求得最终优化方案 ,比较普通直达列车和重载列车开行方案的不同。计算结果表明重载列车的开行应该重新调整现有编组计划 ,而不是仅仅加大原有开行方向上的编成辆数以实现重载 This article first briefly introduces the current situation of heavy-haul transport in our country, and then establishes a heavy-haul train destination model. The introduction of an advanced algorithm - genetic algorithm to solve the model, based on the final optimization program to find, compare the ordinary direct train and heavy-duty train to open different programs. The calculation results show that the opening of a heavy-haul train should readjust the existing marshalling plan instead of just increasing the number of marshals in the original maneuver to achieve overloading
