    Evolution of RCM Evolution of RCM Presentation Transcript

    • Evolution of RCM The Aladon Network
    • The Evolution of RCM 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 BASIC RCM US aviation industry became uncomfortable with validity of existing maintenance practices FAA/industry task force formed to investigate capabilities of preventive maintenance Learned that scheduled overhaul has little effect on the reliability of complex systems and that scheduled maintenance has no effect on some items Rudimentary decision diagram developed Maintenance steering group refines the decision diagram into a process now called MSG1 and apply it to Boeing 747
    • The Evolution of RCM 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 First decision diagram MSG1 developed and applied to Boeing 747 MSG2 developed: applied to DC10 and TriStar US Department of Defence asks United Airlines for a report on how the airlines develop maintenance programs Nowlan and Heap report entitled “Reliability-centered Maintenance” Introduction of the term “Reliability-centered Maintenance”: it is not a generic term, but applies to the strategy formulation process described in the N&H report

    • The SAE standard JA1011/JA1012
      • “ Since the initial work done by Nowlan and Heap, RCM has been used to help formulate physical asset management strategies in almost every area of industry, in almost every industrialized country in the world.”
      “ However, the widespread use of the word RCM has led to the emergence of a number of processes that differ significantly from the original and that fail to achieve the goals of Nowlan and Heap. Some are counterproductive.” “ In response, there has been a growing international demand for a standard that sets out the criteria that any process must comply in order to be called RCM. The result is the SAE Standard JA1011/JA1012.”
    • Advantages to using a Standardized Approach
      • Focus on plant performance and reliability yields returns 10 to 100 times greater than achieved by focusing only on maintenance costs
      • Involves maintainers and users in applying RCM: high ownership of results and commitment to best practice throughout the organisation
      • Tries to identify all reasonably likely failure modes at appropriate levels of detail: results are less risky and much more defensible
    • Risks of using a Non-Standardized Approach
        • Financial returns lower
        • No ownership of results
        • Little or no change of behaviour and attitude of users/maintainers
        • Always miss many more significant failures than standardized methods, so results are more dangerous and less defensible
        • Often take longer and in fact cost more to apply
