FaultTree+ Training Course

The course instructors have extensive experience in providing systems reliability training worldwide. Summary details for our popular Fault Tree Analysis Workshop are given below:

  • Introduction. Definitions of reliability terminology, such as system unavailability, unreliability and failure frequency, concept of risk, F-N curves.
  • Fault Tree Construction. Definitions of gate and event symbols, system and component events, construction rules, and tutorial on constructing a simple fault tree.
  • Minimal Cut Sets. Converting the tree structure to a Boolean representation, eliminating redundant sets, evaluating sets with a computer program.
  • Component Failure and Repair Models. Introduction of the failure models used by FaultTree+ to calculate component unavailability from component failure characteristics.
  • System Quantification. Calculating cut set unavailability and failure frequency, then using that to calculate TOP event unavailability and failure frequency and other system parameters.
  • Importance Analysis. Introduction to Fussell-Vesely Importance, Birnbaum Importance, and others. Enables the user to see which component failure contribute the most to system failure.
  • Common Cause Failures. Taking into account failure modes which may affect multiple otherwise-independent systems.
  • Initiators, Enablers, and Sequencing. When order of failures is important. How to tell the program that system failure may occur only if component failures occur in sequence.
  • House Events. Re-configuring the fault tree to examine how preventive maintenance options may affect over-all reliability. Performing ‘what-if’ analysis on different design ideas.
  • Event Tree Analysis. Constructing an event tree, analysis methods, quantifying consequences, F-N curves.
  • Markov Analysis. Constructing a state diagram to model strong dependencies among a system of components, such as maintenance queuing, start-up delays, and repair phases.
  • Weibull Analysis. Using historical data to predict a failure rate curve for a given failure or repair process. The Weibull module integrates with Fault Tree to allow users to base block failure rates on real-world data.
  • Reporting. Using Isograph’s Report Designer to create and publish text column, text row, graph and diagram reports.
