The quantitative and qualitative analysis about the probability and reasons which result in incidents is proposed by the comprehensive demonstration for FTA,and by combining with finding and removing a failure of the carrier artillery to illustrate application of fault tree analysis in carrier arming maintenance.

With the request of the technical support of warship communication equipment,expert system is used to deal with the actual troubles of warship communication equipment fault diagnosis.

The damage risk of shipboard equipments subjected to the impulsive loads poses challenges to the combat capability of naval ships.

The requirements for maintaining and supporting navy vessels equipment will be updated due to increase in the intensity of destruction to warships equipment on the condition of information-based sea warfare.

With the development in warships equipment, control software has become a core of warships equipment, and the control software maintenance is more and more importance.

This paper focuses on the structure of the integrated diagnosing technology based on information model, and proposes the integrated diagnosing system framework, which is meaningful for the warship equipments maintenance and diagnosis.
