China Railway Train Working Diagram Compilation System

In order to realize computer drawing with network and dynamic management, the passenger and freight train operation diagram, "China Railway Train Diagram Compilation System3.0" is developed, which is accessible to draw train diagrams with remote network and collaboration. With a brief related background introduction of drawing train diagram by computer in our country, system functions are highlighted. Key technologies of the system, for example, satisfaction optimization method of the train operation diagram based on hierarchical decision, train operation diagram data structure design method based on railway sections and technique based on group collaboration are studied.
