Performance Metrics Assessment Method on Aircraft Prognostics and Health Management

Targeting on the verification and validation of prognostic and health management functional design, the performance assessment metrics and methods are rare. Aiming at establishing an application-oriented metrics system model, a set of testability, diagnosis, prognosis and efficiency algorithm performance metrics for the PHM system is described on the basis of performance requirements. The analytic hierarchy process is used to compare and decide PHM performance metrics system, and the weights are computed. The fuzzy comprehensive assessment is used to generalize the specified metrics. A comprehensive assessment method on performance metrics is proposed by combining the above two methods and the assessment of PHM system function is achieved.
