Abstract Door system is a key subsystem of metro train, and conducting failure analysis to determine the failure modes which have great criticality on door system can be helpful for improving door reliability and perfecting maintenance decision. There being ambiguity in evaluating risk factors, the fuzzy theory is introduced into the TOPSIS to build the fuzzy TOPSIS method. Firstly, to conduct fuzzy evaluation on risk factors of each failure mode and to obtain weighted decision matrix, then the closeness coefficient of each failure mode could be obtained by the weighted decision matrix; finally, by conducting failure analysis on metro door system using this method, it can be concluded that the modes ‘EDCU function is broken’ ‘Nut component wears out’ and ‘Limit switch S1 wears out’ have great criticality on door system. The result is consistent with maintenance experts in the field and could provide technical support for design and maintenance of door system.
