摘　　要：在分析现有典型空车调配模型特点的基础上,基于路网结构,核心考虑区间通过能力和不同车种间代用因素,将空车调配相关的走行费用、车种代用费用,以及库存费用共同纳入目标体系,构建了多车种空车调配改进模型,使空车调配更加符合铁路运输实际。通过算例模拟分析,验证了模型的可行性。After analyzing the characteristics of typical empty car distribution models, and based on the railway network structure, the sectional passing capacity and the factors influencing the substitution among different types of cars are mainly considered, and the relative running cost, substitution cost of car type and storage cost are brought into the target system together, and finally the improved model of multi-type empty car distribution is established, which makes the empty car distribution better applicable with the actual situation of railway transportation. In the end, the feasibility of the model is validated through analyzing the calculation examples.
