Research on Network maintenance interoperability evaluation of maintenance support information system

In the network maintenance guarantee, the information interaction platform lacks the evaluation method of interoperability, and the interoperability evaluation is difficult. Interoperability is the foundation for acquiring information in a specific area of networked maintenance. This paper clarifies the interoperation connotation of network maintenance, according to the characteristics of maintenance information system, builds the network support needed for network maintenance interoperation platform, studies the applicable interoperability evaluation model and index system, and constructs the interoperability grade evaluation model of maintenance information system, which has guiding significance for the construction of maintenance guarantee information system.
