Abstract: This paper proposes a predictive maintenance policy using modified failure mode effect and criticality analysis (Mod-FMECA) technique. FMECA is used to identify failure modes, reasons, effects and criticality of the system (machine/plant) but in Mod-FMECA in addition to the analysis carried for FMECA, system performance in terms of output is measured and is used as an indicator to predict the failure mode of the system. The methodology so developed is validated using an example of coal pulverising mill. The proposed methodology helps in minimising the use of costly predictive maintenance equipments. However, further research on the proposed predictive maintenance policy may be carried out in order to extend its applicability to other industrial systems.

Keywords: predictive maintenance; FMECA; failure mode effects and criticality analysis; failure mode and effects analysis; FMEA; productivity; reliability; coal pulverising mills.
