The XML technical is introduced into the supportability analysis, and an oriented object-based XML knowledge presentation method of intelligent FMEA is built in this paper. This intelligent FMEA knowledge presentation method is analyzed amply with an example of failure mode selection knowledge presentation, which integrates the benefits of the oriented object method and XML technical. This method can effectively describe the complex product parts and failure modes and solve the general FMEA knowledge format requirement of the long-range distributed intelligent FMEA, it can also improve the shortage mat the traditional FMEA knowledge can't be used easily in the heterogeneous systems.
