In this research, the reliability and overall cost of unmanned aerial vehicle hangar were studied for two aspects: fault diagnosis and preventive maintenance. The maximum entropy ordered weighted average algorithm was adopted to predict the fault diagnosis of per module in the unmanned aerial vehicle hangar. The cost of preventive maintenance was controlled by adopting the optimal number of preventive maintenances under the object of minimum reliability. The optimization of maintenance cost could be achieved by repairing modules with excessive fault diagnosis rates under the determining preventive maintenance times and reliability. The reliability model of the unmanned aerial vehicle hangar was founded to the series–parallel structure of per module, and its reliability was compared between the regular maintenance and the irregular maintenance. The result showed that the reliability of the unmanned aerial vehicle hangar was more stable under the irregular maintenance. [ABSTRACT FROM AUTHOR]
