Modelling and optimizing sequential imperfect preventive maintenance [PDF]
Reliability Engineering & System Safety, 2009 Abstract This paper deals with the problem of scheduling imperfect preventive maintenance (PM) of some equipment. It uses a model due to Kijima in which each application of PM reduces the equipment's effective age (but without making it as good as new).
