Controllability of Train Service Network

Abstract EN

Train service network is a network form of train service plan.

The controllability of the train service plan determines the recovery possibility of the train service plan in emergencies.

We first build the small-world model for train service network and analyze the scale-free character of it.

Then based on the linear network controllability theory, we discuss the LB model adaptability in train service network controllability analysis.

The LB model is improved and we construct the train service network and define the connotation of the driver nodes based on the immune propagation and cascading failure in the train service network.

An algorithm to search for the driver nodes, turning the train service network into a bipartite graph, is proposed and applied in the train service network.

We analyze the controllability of the train service network of China with the method and the results of the computing case prove the feasibility of it.
