Abstract

Abstract| Preventive maintenance is applied to improvethe system availability or decrease the operational cost.Inthis paper the preventive maintenance with generally distributed parameters are discussed, and the steady-state solution is obtained by solving the underlying semi-Markovprocess (SMP).Specially, periodic preventive maintenancewith deterministically distributed repair time and maintenancetime is discussed in detail, and closed-form results are presented.The behavior of the preventive maintenance mechanism is evaluated by numerical examples.Usingour results, system operational cost can be reduced by theproper choice of optimal maintenance intervals.
