  • 1.  MAINTENANCE STRATEGY

    Posted 06-25-2019 02:58 PM
    Maintenance strategy includes the following but not limited to the list below.
    1.break down or reactive  maintenance
    2. Preventive maintenance
    3. Condition monitoring maintenance
    4. Predictive maintenance
    5. Prescriptive maintenance 
    6. Run to failure and a lot more.

    Question: what factors are to be considered if you are to implement breakdown or reactive maintenance to your plant or facility.
    2. When is it appropriate to recommend breakdown maintenance as a maintenance strategy in your plant.

    Let share our experience and knowledge and grow.

    Joseph,

    Your questions are asked without regard to strategic hierarchy. Before the questions have answers, they must be preceded by detailing how the parent firm competes and wins returns and their chosen business competitive strategy. Thence, the maintenance strategy is formed as a fit to the business strategy. In other words, you would find that from the fit, the answers to your type of questions emerge around the mission of assets and facilities in business competitiveness. Furthermore, the financial ramifications of your maintenance strategies are tested up through the business strategy for their ramifications to business returns.

    Chapter3: Strategy for Competitiveness and Returns of the pdf-book, "Maintenance Reinvented and Business Success," explains the issues and process to arrive at the maintenance strategy from business strategy.

    The free pdf-book can be downloaded at https://analytics4strategy.com/mntcreinvented  A bound paperback copy can be purchased via Amazon.


    PS: There is not an issue of whether or not to introduce breakdown or reactive maintenance. The principle is to conduct all types of maintenance as an optimized for assets and facilities to fulfill their mission in the business strategy.

    One other source could be to refer to RCM strategies which have a category "run to failure" and rest could be some aspects of Preventive or Predictive Maintenance or re-design. Please refer to RCM decision tree as one source for this.

    In my understanding,

    Run To Failure as a Strategy depends on the following:

    1. Criticality of the Asset/Equipment to the Plant: Potential Candidates are Desirable (least Risk) Assets in the Asset Criticality and Classification
    2. There are no unacceptable Risks from Asset Failure ((HSEF Risks and Financial Risks (Production Impact/Consequential Damages to other Assets/Breakdown Maintenance Cost),
    3. When RTF is only the Option/Choice available based on the Asset, Nature of Failure, Failure Mode and Failure Mechanism (other Maintenance Strategies are n't effective)
    4. When the Cost of performing Proactive Maintenance (Preventive Maintenance or Condition Monitoring) exceeds the Cost of Repair/Replacement of the Asset on Failure
    Also, when RCM/FMEA is performed on Critical Systems/Assets and the Maintenance Task Selection as per Decision Tree leads to RTF as the Strategy for a particular Failure Mode

    Hope this helps

    All the advisements in strings such as these for maintenance strategy suggest that we are minimizing business strategy as the North Star to maintenance strategy which must be designed to fit business strategy.  A HUGE OMISSION!

    Chapter 3, Strategy for Competitiveness and Returns of the pdf-book (https://analytics4strategy.com/mntcreinvented), "Maintenance Reinvented and Business Success," was written to establish five principles of competitiveness that must be considered to establish business strategy and then maintenance strategy as a fit. The second part of the chapter provides a stepwise project procedure for applying the principles.

    The original intent of the field of availability engineering (earlier called integrated logistic support-ILS) was to be a process that extends business strategy to maintenance strategy. At some point "mission" is established for each asset in the grand scheme of the enterprise strategy. At the end of the analytical procedure, the asset-level reliability, maintenance and criticality scheme for some assets will be different when evaluated in context than if not.

    I'm with Richard Lamb on this one.   I will use different words to perhaps enhance understanding.

    Every maintenance strategy and tool deployment has the singular goal of eliminating waste.    Waste in: production downtime, inefficient maintenance resources, poor quality, not running at design rates, excessive outage duration, etc.     Understand the waste at your plant; link to the business case; then remove the waste using the appropriate strategy taking into account the long view.     All strategies are good and all are bad depending on the business case.

    By the way... waste at your plant is best known through personal observation.    Look up Chalk Circle Observation by Taichii Ohno.     Use extreme caution accepting KPIs, meeting discussions, and opinion as truth.     These are filled with bias to prevent embarrassment.
