Research on large-scale train operation simulation;

Design of peripheral supporting environment for train operation and organization simulation based on railway network;

The paper defines a fuzzy time Petri net (FTPN) applied to the train operation system.

The basic thought and principle of Hungary s method are elaborated,combining the factual candition of the railroad train movement.

Based on the idea of Objected-Orientation and the conception of system theory, a design and an implementation of train movement calculation on urban rail system are presented.

It was firstly analyzed the necessity of system of weaving train running adjust plan by computer and introduced some foreign similar systems.

This paper describes line characteristic of urban railway with mathematics methods, with the same interval time of train running as target function to make mathematics model of urban railway.

On the basis of analyzing the relationship between train running and signaling system,a train running model based on agent technology(TRAC) was applied to solve train running problem under different pattern signaling system.

Satisfactory rate function is designed to represent the satisfactory rate of the performance specification in the model, in addition, the synthesis satisfactory rate function is constructed with the fairness law, and the satisfactory optimization model and solution of adjusting train diagram on double track railway are produced.
