A Mixed Integer Linear Progrom(MILP) model is established considering the number of arrival-departure tracks, the speed restriction for maintenance. The constraints are classified according to their characteristics, and some kinds of constraints, e.g. the number of arrival-departure tracks constraints are decomposed using row generation, then the model is solved by commercial software GUROBI. The model and algorithm is tested on a calculation example, in which different decomposition methods are compared, and a two-stage approach is applied to deal with the complex maintenance restriction constraints. The results show that decomposing the number of arrival-departure track constrains can improve the solving efficiency by 25%~45%, and whether it’s beneficial to decompose the headway constrains depen-ding on the solving scale. %K 铁路运输 %K 列车运行图 %K 行生成 %K 维修天窗 %K GUROBI< %K br> %K railway transportation %K train timetabling %K row generation %K maintenance skylight %K GUROBI %U http://jdxb.bjtu.edu.cn/CN/abstract/abstract3322.shtml
