The improvement of system reliability can be achieved by improving the reliabilities of its constituent components. This could be done through maintenance actions that are performed on the components. There are two extreme states in which a component could assume following a maintenance stage; bad-as-old (BAO) or good-as-new (GAN). For some components of the system, the maintenance actions may bring them to an in-between state. This in-between state is achieved under the assumptions of imperfect maintenance. This paper investigates the improvement in reliability of a component and system in the in-between state through imperfect preventive maintenance policy. Thus, it establishes a mathematical model for component reliability evaluation under assumptions of imperfect preventive maintenance.
