Service-oriented architecture on the Grid for integrated fault diagnostics

For industrial fault diagnostics, many model-based fault diagnosis approaches have been proposed so far and some of them have been put into practice. However, for modern complex processes, owing to the variable nature of faults and model uncertainty, no single method can diagnose all faults and meet different contradictory criteria. In this paper, the importance of integration of different fault detection and isolation schemes in a generic problem-solving environment is emphasized. A service-oriented architecture for the integration is proposed, based on Grid technologies. As an engineering implementation, a decision support system for the gas turbine engine fault diagnosis is presented and some deployed services are discussed. Copyright (c) 2006 John Wiley & Sons, Ltd.
