Abstract: System safety assessment is a technique aiming at identifying hazards for the system under analysis and showing the compliance with the safety requirements. In order to increase the safety of a system, one may select components in the system for preventive maintenance, under the constraints of maintenance cost, maintenance time and the availability of maintenance staff. In different maintenance policies, maintenance cost can differ. This paper proposes some measures for component preventive maintenance considering maintenance effectiveness, based on which the expected costs due to a component and the system are investigated, respectively. Three different maintenance cost scenarios are analyzed for different maintenance policies. Considering both cost and maintenance constraints, components are optimally chosen for preventive maintenance. An application of a hydraulic system for an aircraft is then used to illustrate the proposed method.
