Reliability Concepts

Twelve short articles on the ideas that underpin modern reliability, availability and maintenance engineering. Each piece explains one concept, why it matters, and how tools such as Isograph Availability Workbench and Reliability Workbench let you discover the benefit with your own data. Each article also points to the deeper resources on this site: our white papers, podcast episodes, services and training courses that take the concept further.

Written from decades of RAMS practice across Australian mining, rail, utilities, oil and gas, and manufacturing, in the same spirit as the rest of this site: no jargon for its own sake, and no method recommended without a reason.

Modelling Foundations

  • RBDs and Fault Trees: Two Lenses, One System. Success logic and failure logic are mathematically equivalent. Why fluency in both sharpens your modelling.
  • Your Risk Matrix Is a Model. Treat It Like One. Connecting the corporate risk matrix to live reliability models.
  • Monte Carlo Simulation: Run Your Plant a Thousand Times. Why complex systems demand simulation, and what the results are really telling you.

Working With Data (and Without It)

  • No Failure History? You Still Have Data. Structured elicitation, Weibull shape parameters and the greenfield project problem.
  • Suspended Data: Why the Survivors Must Testify. How ignoring censored data biases estimates and triggers replacement programs that were never needed.

Strategy and Economics

  • Lifecycle Cost: Where Reliability Meets the Boardroom. Translating MTBFs and betas into the financial anatomy of an operating strategy.
  • Spares Strategy Is a Reliability Problem. Holding cost versus risk cost, and why the answer depends on your failure distributions.
  • RCM Is Not Paperwork. It Is a Decision Engine. Consequence-driven maintenance and the cost-benefit ratio that ends workshop debates.
  • The P-F Interval: The Most Practical Curve in Maintenance. Inspection intervals, condition monitoring and failure on your schedule.
  • Do Not Model Everything. Model What Matters. Criticality-first analysis and the discipline that keeps models alive.

Safety and Integration

  • Functional Safety and SIL: Reliability Maths With Legal Weight. IEC 61508, voting architectures, common cause failure and the safety case.
  • Your Reliability Model Should Talk to Your CMMS. SAP, Maximo and the pipeline that turns a study into a living asset.

Go Deeper

These articles are deliberately short. The long-form treatments live in our white paper library, and many of the same themes are discussed in conversation on the Speaking of Reliability podcast episodes featuring Philip Sage. For hands-on capability, our training courses cover RAMS, availability simulation, RCM, fault tree analysis and root cause analysis. And for where these methods are heading as a connected platform, see the PeakAvenue software pages.
