Unavailability Optimization of a System Undergoing a Real Ageing Process Under Failure Based PM

Popis výsledku v původním jazyce

This chapter deals with the exploration of the system which acts on demand in case of emergency matter. To verify functionality the system must be regularly inspected with a given period and tested to find latent failures. A failure-based preventive maintenance is considered, in context with the imperfect corrective maintenance model. This means that preventive maintenance brings full renew which is realized after a prescribed number of failures. If a failure occurs, it is detected during the first follow-up inspection and the restoration process starts. The imperfect corrective maintenance model is intended where each restoration deteriorates the system lifetime whose probability distribution is gradually changed via step by step rising failure rate. Reliability mathematics for unavailability analysis is briefly outlined in this chapter. The new renewal process model, including the failure-based preventive maintenance, has been designated here as a real ageing process. The imperfect corrective maintenance as well as increasing period between inspections result in undesired rise of unavailability which can be corrected by the properly selected failure based preventive maintenance. This optimization process is demonstrated on a selected system adopted from references. (C) 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
