Abstract: Reliability analysis of CNC machine tools needs mass data, which is various, correlative and distributed. It brings many challenges to the information system for reliability. This paper proposes an information model to organize and analyze the data efficiently. Information-exchange and information-sharing patterns during various stages of service life are formed according to users’ requirement and platforms adaptability. The XML Schema and XML documents are established to uniformly describe the reliability information. The reliability system is designed, so as to provide the solution to the reliability information management for machine tools’ enterprises.

Key words: machine tools, reliability management, information model, XML Schema view, XML index
