This thesis analyses a maintenance optimization problem of a critical unit used in military systems. It is aimed to model the stochastic deterioration behavior of these units and develop some maintenance policies. For this purpose, periodic inspection times which maximize expected time to failure are proposed to be able to provide preventive maintenance before failures. In the scope of this work, resistance measurements from the field are gathered for ten months. First, functions representing the increase in resistance are obtained. Then they are transformed into the deterioration condition of the unit. Then optimal maintenance policies depending on these conditions are found for various objectives using Markov models.
