Abstract:
Maintenance practices within the military have historically relied on two main practices, failure replacements, and schedule or usage based preventative maintenance replacements. However, the Department of Defense DoD mandated Condition Based Maintenance CBM with DoD Instruction 4151.221, These instructions indicate that CBM shall be used as the principal consideration for selection of proper maintenance concepts. The implementation of CBM measures in accordance with the policy is required of the program managers through requirements of the Secretaries of the Military Departments and the Directors of the Defense Agencies. The implementation of the program should be in accordance with the Condition Based Maintenance Plus DoD Guidebook 2. The guidebook breaks down maintenance into reactive and proactive. Reactive maintenance is performed on items that are run to failure. Proactive maintenance is broken down further into preventativescheduled maintenance or predictive maintenance. Preventative maintenance is either based on a schedule or based on a trigger that may lead to failure e.g. a visual oil leak. Predictive maintenance is either diagnostic or prognostic. Diagnostic identifies impending failure and prognostic adds a prediction of remaining useful life. The DoD intends to implement CBM to reduce maintenance costs and improve the readiness of their assets. Figure 1 provides a visual representation of the planned DoD transition.
