    • 1. Reliability Engineering Fred Schenkelberg fms@fmsreliability.com
    • 2. EQUIPMENT SELECTION AND REVIEW Day 2 Session 4
    • 3. Objectives • Examining the lifecycle process • RAM modeling to evaluate designs • Conducting the Maintainability Design Review • Developing a MDR checklist
    • 4. Lifecycle Process Concept Design MFGUse End of life
    • 5. Concept & Design Concept • System Architecture • Reliable v Available • Goal setting Design • Selection of materials • Selection of components • Risk identification • Tradeoffs
    • 6. Production & Use Production (manufacture) • Process variation • Materials variation • Shipping variation • Installation variation Reliability only gets worse Use • Operation Stress • Environment Stress • Maintenance Plan • Failure Detection
    • 7. End of life Decommissioning • Lessons learned • Tear down and analysis • Reliability Differences with today’s model
    • 8. Discussion & Questions
    • 9. Reliability Modeling • Focus on function – Common – Perfect product • Focus on reliability – Uncommon – Imperfect product • CAD, FEA, Simulations
    • 10. Design Comparison • Reliability occurs in the design • Selecting the most robust options • DOE, Stress/Strength, Aging, Maintenance Costs, Failure Costs
    • 11. What if analysis • What could go wrong? • Explore changes to – Environment – Construction – Use profile – Materials Good designer do this naturally
    • 12. System Modeling • Simulate different – Maintenance policies – Maintenance practices – Supply chain changes • DOE to design the experiments • Output is cost of ownership and availability
    • 13. Discussion & Questions
    • 14. Design Reviews • Adversarial or Constructive • Formal or informal • Status update or detailed design check How do you approach reviews?
    • 15. Stages of Review • During design – Risk assessment – Options and benefits – Decisions • During review – Increase awareness – Identify errors (Petroski) – Celebrate failures • After review – Process improvement – Lessons learned
    • 16. Hosting a review • What is the purpose? • What decisions are being made? • What is desired outcome? Be clear on why
    • 17. Considerations • People – Knowledgeable – Stakeholder – Perspective • Timeline – Time for details – Time for action • Meetings – One on one – Group
    • 18. Discussion & Questions
    • 19. Review checklists • Avoid using a checklist or database – Detailed checks, i.e. keepouts, sizing, etc. – Goal is do the checklist • Do use the approach guided by checklist – Higher level – Range of stresses
    • 20. Review guidelines • Brainstorming approaches – Day in the life – Range of stresses – Change one thing • Make it safe to talk about failure – Not personal – No attacks – No solutions (take offline)
    • 21. Checklist cautions • Design checklists • Testing checklists • Review checklists Only works if you know everything and follow the spirit of the checklist
    • 22. Golden Nuggets • An example that has been very effective • Identify key failure patterns • Review before and after project – What will you do? – What did you do?
    • 23. Discussion & Questions
    • 24. Summary • Examining the lifecycle process • RAM modeling to evaluate designs • Conducting the Maintainability Design Review • Developing a MDR checklist Equipment Selection & Review
