Three-dimension train group operation simulation system based on Petri net with objects

The paper presents a three-dimension train group operation simulation system, which is designed depending on the existed definition of train operation Petri net with objects (TOPNO) and adopts some discrete event dynamic system, hybrid system theories and effective adjustment control mechanism. It has small scale and the advantages in flexibility, modularization and operability etc. Three-dimension modeling technique and inheritable storage organization manner realize train operation three-dimension visual simulation. Thus, compared the existed traditional two-dimension train group operation simulation system, the system is obvious, flexible and can be better operated and supply more information. The experiment in this paper demonstrates the feasibility and utility of this system.
