Optimum Preventive Maintenance Policies for the AMRAAM Missile

<p>The overall objective of this research effort was to formulate a preventive maintenance strategy for AMRAAM missiles subject to extended captive carry flight time. A preventive maintenance policy is only applicable if the item in question is aging or deteriorating with time. Therefore a supporting objective of this research is to characterize the aging process of the missile system through a non-parametric analysis of its Mean Residual Life (MRL) function. Three non-parametric censored-data MRL function estimation techniques discussed in the literature are examined via a numerical example. All three estimation techniques provide MRL functions that exhibit greatly exaggerated decreasing trends compared to the MRL function of the underlying distribution in the example. A semi-parametric technique for estimating the MRL function is developed that shows dramatic improvement over the non-parametric results. Although the MRL analysis of the current AMRAAM failure data failed to provide evidence that the missile system is aging three preventive maintenance policies discussed in the literature are investigated.</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
