Abstract

Protection systems are usually required to function in the case of specific demand events; they can have hidden failures, which can only be verified through inspection or during demand events. In many cases, inspections are subject to errors in the identification of the system’s state, and when it is not possible to reproduce the usual operating conditions during an inspection, such errors may even result in the identification of the failure state. A delay-time model for a hybrid inspection and preventive replacement policy applied to a protection system is presented, considering misclassification errors in inspections so that it is possible to estimate the expected cost rate in the long run and the expected rate of unmet demands. A multicriteria model based on the application of the multi-attribute value theory (MAVT) in the context of shut-off valves used in sewage collection systems is presented to show how the model can be used to define a maintenance policy that presents the best compromise relationship between those two criteria and to evaluate the best investment conditions in maintenance quality improvement.
