It presents significant differences from redundant systems in previous studies on cold, warm or hot stand-by components. These are the dissimilarity between the filter and the bypass, as the latter can induce catastrophic damage after a long working period, and the stochastic dependence between the filter and the bypass valve. Inspection and testing is focused on the valve, and only if it fails to open on inspection, or it is found to be open, is the filter inspection triggered. Preventive maintenance is mainly concerned with the filter, which is replaced periodically and also when an inspection detects an open valve or a clogged filter. The sensitivity analysis reveals that the optimum policy depends more on the parameters defining the lifetime of the filter than on those of the valve. info:eu-repo/grantAgreement/ES/MICINN/PID2021-123737NB-I00 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 11.0 2024 OPERATIONS RESEARCH & MANAGEMENT SCIENCE 2 / 106 = 0.019 2024 Q1 T1 ENGINEERING, INDUSTRIAL 3 / 69 = 0.043 2024 Q1 T1 2.647 2024 Applied Mathematics 2024 Q1 Safety, Risk, Reliability and Quality 2024 Q1 Industrial and Manufacturing Engineering 2024 Q1 19.1 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Calvo, E.
