This chapter surveys the earlier results of imperfect preventive maintenance (pm) models which could be applied to actual systems; (i) the unit after pm has the same hazard rate as before pm, (ii) the age of the unit becomes x units of time younger at pm, and (iii) the age reduces to at when it was t before pm. The expected cost rates of each model as an objective function are obtained and optimal policies which minimize them are analytically discussed.
