Research on ontology-based maintenance knowledge expressing of power plants

As maintenance knowledge management is an important issue of maintenance of power plants, expresses and organizes the maintenance knowledge effectively is the key link in this field. Taking the ontology research results used in knowledge management field for reference, ontology technology is introduced to conception modeling for maintenance of power plants. S-B-F-P maintenance knowledge expressing model based on ontology is proposed and the classification method of maintenance ontology is created. It makes the knowledge reused and shared possible and brings an effective settlement method for increasing the swarm cooperative maintenance decision.
