In order to improving the vehicle equipment support capacity under the system operations based on information system, put forwards a standard system of vehicle equipment maintenance support based on standardization system engineering (SSE) theory. Around the two main tasks of establishing the standard system, it firstly simply introduces the SSE methodology, then, it gives its application methods, establishes the three-dimensional structures of standard system research, and at last, verifies and analyzes its application. The analysis result shows that the structure of the standard system is designed reasonable or not directly determined the system’s functions and its existence value.
