摘要：Aiming at the shortage of the existing importance evaluation for multistate units and the empha-sis about units in maintenance,the concept of maintenance importance(MI)is introduced which balances three causes:risk degree,units importance to system reliability,detection difficulty.MI can provide maintenance pri-ority results for units at any given time quantitatively and offer units maintenance sequence for the follow-up ma-intenance.The general idea of system predictive maintenance is put forward combing MI and goal-oriented Methodology.A comprehensive predictive maintenance platform is built which contains reliability assessments, units importance estimation and maintenance strategy.Finally,the proposed algorithm is applied into some strap down inertial navigation system.The simulation results prove the proposed design ideas are feasible,and the evaluation results can provide support for the implementation and optimization of the following maintenance.
