With the rapid development of urban rail transit, huge metro systems have been built, which is the best choice for people due to the efficiency, safety and punctuality. Therefore, the quality of service (QoS) of metro systems has attracted the attention of operators especially when unexpected event happens. In the paper, based on the graph theory, a resiliency assessment method is proposed to quantitatively measure the performance of a metro network. We represent the metro network with an undirected graph where the metro stations are described using the nodes while tracks are demonstrated with the edges. The performance evaluation of a metro network is implemented through the resiliency assessment of one node, where weighted degrees and the weighted sum of reasonable routes to the other nodes in the network. The resiliency of a node can be obtained by the performance degradation of the original network with the corresponding node being removed. Shanghai Metro is taken as the example to perform the proposed approach which is verified through the numerical results in the paper.
