Scheduling Model and Algorithm of Using Up-and-down Lines on Railway Marshalling Station
铁路编组站到发线运用的排序模型和算法

The key problem of how to make the plan of using up\|and\|down lines in the process of computer aided dispatching for railway marshalling station is studied in this paper. Scheduling model of using up\|and\|down lines is set up by analyzing the characteristics of time intervals set that train use up\|and\|down lines. The algorithm of this is given by construction method.
