Shunting operation is an important link in enterprise railway transportation,its working efficiency has decisive impact on railway transportation ability and enterprise’S scale of production. Not only can be verified the feasibility of route automatic selection strategy and simulation model,but also it’S a good way to improve the transport efficiency and reduce the cost of enterprise railway transportation for deeply researching shunting operation at enterprise railway by the extensive puter simulation
technology.
On the background of shunting operation of special railway in Zhuzhou Smelter pany,this paper mainly does research in the simulation method for route automatic selection of shunting operation and its application.
Firstly, based on analyzing puter simulation technology and corresponding fruits in railway transportation field, and considering the characteristics of shunting operation in enterprise railway—transportation,a thought which tries to implement its simulation in view of discrete—event is order to implement the shunting operation simulation,puter simulation model is built,and the simulation strategy is designed.
Secondly,to seek a reasonable security shunting operation route as the goal,according to the characteristics of enterprise railway transportation,the consisten
