Calculation of failure criticality in Reliability - Centred Maintenance

Abstract

The paper presents methodology for calculation of criticality of failure of components of technical systems in reliability-centred maintenance. Criticality of failure is complex function that depends on the adopted criteria: safety, standstill duration, quality of system functions during the malfunction, total costs and frequency of failures. Depending on characteristics of the analyzed system, the criteria for calculation of criticality may be extended or reduced, and the degree of their influence may be increased or decreased. The proposed methodology is applied to the case of pump station for water supply.
