In this paper, we present a new centralized shunting model based on the analysis of the relationship between the automatic commanding system and the shunting organizing model. The presented model uses the shunting equipment centrally to realize multiple shunting goals by full-batch and high-depth operation. We specify the conditions for centralized shunting operation and point out the main behaviors of blind dispersive shunting operation by discussing the difference between them. Then, we discuss the efficiency of the centraliced model and the necessity of pursuing centralized shunting. Finally, we put forward suggestions on how to realize centralized shunting in a automatic commanding system.
