Maintenance optimization under non-constant probabilities of imperfect inspections

In this research, we study a single-component system that is characterized by three distinct states, cf. the Delay Time Model: normal, defective, and failed. The system is maintained by an inspection policy with fixed time intervals, and preventive system replacement after a number of inspections. The inspections are imperfect, and the probability of an inspection error changes over the system’...

Repairable systems availability optimization under imperfect maintenance

This paper deals with the modeling of a preventive maintenance strategy applied to a single-unit system subject to random failures. According to this policy, the system is subjected to imperfect periodic preventive maintenance restoring it to ‘as good as new’ with probability p and leaving it at state ‘as bad as old’ with probability q. Imperfect repairs are performed following failures occurri...

Inspection and maintenance decisions based on imperfect inspections

The process industry is increasingly making use of Risk Based Inspection (RBI) techniques to develop cost and/or safety optimal inspection plans. This paper makes use of the gamma stochastic deterioration process to model the corrosion damage mechanism. This model is successfully extended to update prior knowledge over the corrosion rate with imperfect wall thickness measurements. This is very ...

Redundancy System Fault Sampling Under Imperfect Maintenance

When conducting simulation for evaluating complex system reliability or availability, method of random sampling is applied to simulate fault occasion of complex system. Current research of fault sampling generally assumes maintenance activity restores systems to “good-as-new” and “bad-as-old” without considering “partly good” situation. However, system usually keeps its function through imperfe...

Optimal maintenance decisions under imperfect inspection

The process industry is increasingly making use of Risk Based Inspection (RBI) techniques to develop cost and/or safety optimal inspection plans. This paper proposes an adaptive Bayesian decision model to determine these optimal inspection plans under uncertain deterioration. It uses the gamma stochastic process to model the corrosion damage mechanism and Bayes’ theorem to update prior knowledg...
