装车地直达列车编组计划的优化模型

The Optimal Model of the Direct Train Formation Plan for Loading Area

本文主要讨论了装车地直达列车编组计划的优化问题。在充分分析组织始发直达列车的必要条件及参数选择的基础上，构造了装车地编组计划的非线性０─１规划模型，与现有工作相比，该模型更全面地描述了始发车流的各种组合开行方案，从而避免丢失更好的始发直达方案。此外，文中还给出了模型的复杂性分析及构模实例。

This paper addresses the direct train formation plan problem for loading area. Theproblem has been formulated as a nonlinear 0-1 programming based on discussing the costparameter and block capacity constraints at loading station in great detail.Theobjective ofthis model is to determine a classification optimal strategy for alI O-D pairs in a loadingarea.Comparing with the previors reseach,this model is comprehensive and incorporating theessential features of the problem and avoids losing the optimaI train connections and blockingstrategy.The complexity and instance of the model are givin at the end.
