Optimum Maintenance Policy of a Periodically Inspected System under Imperfect Repair
This paper deals with the maintenance policy of a system subject to periodical inspections aimed at detecting the occurrence of failures. After the first N−1 failure, the system undergoes an imperfect repair that brings the system back to the operating condition while the Nth failure is followed by a perfect repair restoring the unit to an as-good-as-new condition. The limiting average availabi...
متن کاملCondition Based Maintenance of Periodically Inspected Systems
Condition based maintenance (CBM) is a powerful tool for improvement of system reliability and reduction of system downtime. This research considers CBM under which the system state is periodically observed with or without observational error, and maintenance is imperfect. System availability is maximized by determining the optimal maintenance threshold and the time interval between consecutive...
متن کاملCondition-based maintenance under an imperfect repair policy for a deteriorating production system
This paper presents a condition-based maintenance policy taking into account both maintenance cost and production capacity aspects for single unit deterioratin production system whose condition is periodically monitored. Imperfect preventive maintenance activities, which restore the production system to better states and might not be as good as new, are considered. We assume however that the sy...
متن کاملRedundancy 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...
متن کاملOptimal Periodic Maintenance Policy under the Arithmetic Reduction Age Imperfect Repair Model
This paper presents the preliminary results of a research work on procedures for the determination of optimal maintenace policies under imperfect repair assumption. The topic was motivated by a real data set on failures of off-road trucks used by a mining company. In particular, it is discussed the determination and practical implementation of an optimal preventive maintenance policy using the ...
