Survey of stage plan for railway marshalling station

Abstract

The optimization of stage plan for railway marshalling station remains as a hot and difficult spot in research of railway transportation organization in China. The purpose of such research is to realize computer-aided dispatching and to construct the intelligent dispatching system for the marshalling station. Up to now, multiple results have been achieved on the theories and methods of stage plans. On the basis of analysis on the main contents of stage plans, this paper puts forward a brief survey of stage plans under certain and uncertain environments, and with computer-aided dispatching methods and systems. Then, the existing and unresolved problems in application of the current theories and methods, and the direction of future research of stage plan are investigated.
