Research on Ontology Based Maintenance Knowledge Expressing of Power Plant
Zeng Hongtao · Water Resources and Power · 2007
Condition-based maintenance(CBM) is a system engineering,which involves the maintenance procedure in every stages.Aiming at the problems of knowledge expressing and information organizing in maintenance of power plants,the ontology used broadly in knowledge engineering is introduced to the conception modeling for maintenance of power plant.S-B-F-P maintenance knowledge expressing model of power plants based on ontology is proposed and the classification method of maintenance ontology is established.Then the method of knowledge description is standardized,which makes the knowledge reused,shared,commuted possibly and brings a effective settlement method for raising the swarm cooperative maintenance decision.
