Maintenance and Appraisal Expert System Design and Knowledge Library Construction for Electronic Recycled Equipment of Certain Missile

The electronic equipment recycling can effectively save the equipment guarantee cost and meanwhile improve the service efficiency of the equipment. The key point for electronic equipment recycling is the repairability and the repair cost of the equipment. Firstly, the paper aimed to analyze the fault characteristics and the basic maintenance and appraisal principle of the electronic recycled equipment of the guided missile; then, the paper aimed to determine the fault diagnosis method and establish the maintenance and appraisal model for the electronic recycled equipment of the guided missile; finally, the paper aimed to provide the method for constructing the expert system knowledge library, thus providing relevant reference for the electronic recycled equipment of other weapons.
