According to the expandability,utility and team-working mode,a Network Based multi-user Cooperative(NBC) train working diagram system was built by adopting three-layer application architecture which combined B/S mode and C/S mode.NBC system was composed of client(user service layer) and server(Web service layer/application service layer/data service layer),including many subsystems,such as user and cooperative control subsystem,base data management subsystem,site group management subsystem,train working diagram scheduling and modifying subsystem,locomotive routing management subsystem,indicator and capacity analysis subsystem,basic technology support and extended service subsystem,etc.Some models were proposed for NBC train working diagram system,such as model for programming the timetable,model for planning station technical operation and model for laying out locomotive routing.A network based multi-user cooperative mode was also presented.Through the development of the prototype system and the trial operation in Haerbin Railway Bureau,the constructed NBC train working diagram system is proved to be technically feasible.
