It is obvious that in order to keep normal operation of a metro system, tremendous works are needed for its maintenance, nevertheless how to get optimum maintenance solution is still a critical problem to be solved. This paper presents a Fuzzy-Set based theoretical approach for verifying the reasonability of current methods in maintenance, determining whether a device or facility system should be removed from operation for repair while the “Failure Mode and Effects Analysis (FMEA)” is used. Under such case, fuzzy quantitative treatment is operated to the linguistic/semantic expression of the FMEA, which identifies the failure status of the sub-systems (or its components) with fuzzy quantitative information for evaluating its overall deterioration state. A case study of vehicles’ maintenance in a metro network system in Shanghai is presented to show the applicability of the fuzzy treatment strategy to FMEA in the optimization of metro maintenance management.
