3 DISTRIBUTION A. Approved for public release: distribution unlimited. 33 What is Reliability Centered Maintenance? “RCM. A logical, structured process used to determine the optimal failure management strategies for any system, based on system reliability characteristics and the intended operating context. “ (DoDM M) “RCM. a process used to determine what must be done to ensure that any physical asset continues to do what its users want it to do in its present operating context. “ (Moubray) Doing the right maintenance, at the right time, for the right reason

4 DISTRIBUTION A. Approved for public release: distribution unlimited. 44 Who Conducts RCM and Why? Per MCO (GEMP) Commander, Marine Corps Systems Command (MARCORSYSCOM)/Program Executive Office (PEO) As the Marine Corps ground equipment asset (Class VII PEI) life cycle manager, develop, implement, document, assess, and refine program/product management strategies and maintenance support plans throughout materiel life cycle through RCM analysis to support CBM+ concepts and the performance of maintenance within a TPM strategy.

8 DISTRIBUTION A. Approved for public release: distribution unlimited. 88 What Can RCM Achieve? (WIIFM) Optimized Maintenance Strategy Maintenance Effectiveness and Efficiency Higher Achievement of Inherent Reliability and Availability Greater Safety and Environmental Integrity Improved Product Quality Longer Useful Life of Expensive Items Design Improvements A Maintenance Database and increased knowledge of your systems Typically Reduces Maintenance Man-Hours, Logistics Footprint, and Total Ownership Cost Ownership of the maintenance strategy

9 The “traditional view” of failure is based on the notion that everything has a “life” and most failures are age related and that periodic maintenance will improve reliability. Maintenance interval ConditionalProbability of Failure “Age” (Miles/Hours/Rounds/Days/Cycles etc.) "LIFE" The “Traditional View” of FailureWear-OutZone Random Failure

10 The Reality of Failure A C D E F 4% 2% 5% 7% 14% 68% 11% 89% “Reliability Centered Maintenance” 1978 Nolan and Heap for the U.S. DoD B LIFE Random Failure patterns reflecting NO RELATIONSHIP TO AGE Based on several industry and DoD studies, the vast majority of components do not exhibit a life.

11 The Waddington Effect (c. 1943) Flying hours since last scheduled maintenance Scheduled Maintenance * Dr. Jim Ignizio University of Texas, 2010 Unscheduled maintenance per 10 flight hours 11 Dr. Waddington discovered that B-24s were failing at a higher rate just after scheduled maintenance. As failures would taper off over time, scheduled maintenance was resulting in the destabilization of an otherwise stable system.

12 D E F A B C “If it ain’t broke, fix it till it is” 12 The Waddington Effect (c. 1943) For components that exhibit a life, scheduled maintenance makes sense. For components that do not exhibit a life, scheduled maintenance is UNWARRANTED and can be a waste of resources and even damaging.

13 Unwarranted Maintenance  Unwarranted maintenance tasks will result in: Decreased asset availability High repair costs with little or no benefit Maintenance-induced failures No change in safety or reliability A considerable loss in component life 13

14  Unwarranted maintenance tasks will result in: Decreased asset availability High repair costs with little or no benefit Maintenance-induced failures No change in safety or reliability A considerable loss in component life  Unwarranted maintenance tasks can be the result of: Maintenance program developed outside the RCM methodology Developed by the OEM Borrowed from similar equipment “This is the way we’ve always done it” “Good idea” maintenance 14 Unwarranted Maintenance Evidence of Need  RCM identifies alternatives to such tasks & applies the most appropriate maintenance approach based on the “Evidence of Need”. Solution

15 A scientific process used to determine what must be done to ensure that any system continues to do what its users want it to do in its present operating context: 1.What are the functions (or purpose) of the system?  Identify Functions 2. In what ways can the system fail?  Identify Functional Failures 3. What causes the system to fail?  Identify Failure Modes 4. What happens when the system fails?  Identify Failure Effects 5. Does it matter if the system fails?  Identify Failure Consequences 6. Can anything be done to predict or prevent the failure?  Identify proactive tasks 7. What if the failure cannot be predicted or prevented?  Identify default tasks Phase 1: Information Phase Phase 2: DecisionPhase RCM Questions

16 DISTRIBUTION A. Approved for public release: distribution unlimited. 16 RCM Analysis Outputs Proactive Tasks: Scheduled tasks designed to anticipate or prevent failures. - On condition tasks (CBM) - Scheduled Maintenance: (aka “Hard Time”) Rebuild / Overhaul Replacement - Lubrication/Service Default Actions: Actions taken if a proactive task cannot be found. - Failure Finding - Walk-around inspections - Age exploration - Redesign - Run to failure

19 DISTRIBUTION A. Approved for public release: distribution unlimited. 19 ProgramAnalysis Recommendations Assault Amphibious Vehicle (AAV) PMCS Recommended the reduction of 70% of the PMCS tasks on the AAV platform Assault Amphibious Vehicle (AAV) Deadline Criteria Recommended that operational checklists include new columns for deadline criteria and exceptions to non-use Multi-Band Radio II (MBR II) Recommended development of a mitigation strategy for HUB battery removal (bricking) Airtronic Burner Recommended the transition to full organic support at significant cost savings to the USMC Expeditionary Field Kitchen (EFK) Recommended the reevaluation of the upper temperature operating limit contained in MIL STD 810G (120 degrees F) Blue Force Tracker (BFT) Recommendation to investigate a possible redesign to incorporate a software change. If this software change and other recommendations were to be incorporated, the projected 10-year cost decrease to the BFT FoS would reflect a decrease of $464,773 in material costs and a net decrease of 4,863,072 maintenance man-hours at all maintenance levels. Notable Analysis Recommendations
