Subway bogie is an important part of subway. It plays a vital role in the safe and comfortable operation of the subway. Therefore, the reliability analysis of subway bogies has become the focus of attention. In order to solve the problem that different connections between components cannot be well reflected when using the network-based method to analyze the importance of the system, we propose an approach based on multiplex network to analyze the importance of the subway bogie system. After building a multiplex network, we consider the importance of the components by solving the values of degree, closeness centrality and eigenvector centrality. Then, for the problem of too many importance indicators, we use D-S evidential theory to fuse these indicators into a comprehensive importance indicator. Finally, we sort the components according to the comprehensive importance index. The result of the sort will become the basis for our daily maintenance.
