Introduction to Fault Tree Analysis

Duration: 2 Days | Lecture / Workshop

Fault Tree Analysis is one of the core techniques used in reliability, risk and safety analyses. A Fault Tree forms a logical representation of the manner in which combinations of basic events, often made up of failures at the component level, could lead to a hypothesized failure of a system.

This insightful and informative Fault Tree Analysis course offers an introduction to the subject and covers the following areas:

Introduction: Outlines the purpose of Fault Tree Analysis, and explains availability, reliability, failure frequencies, risk and F-N curves.

Fault Tree Construction: Explains the construction of fault trees, gate and event symbols, causal relations and workshops the building of an example fault tree using computer software (ITEM ToolKit).

Minimal Cut Sets: Explains minimal cut sets and the techniques for obtaining them, including a workshopped example.

Basic Probability Theory: Explains basic probability theory, including independent events, exclusivity, and the addition and multiplication laws.

Component Failure and Repair Models: Details component failure and repair models including the constant failure and repair rate, and dormant failure models. Workshopped examples.

System Quantification: Explains system quantification including minimal cut set unavailabilities and failure frequencies, calculating top event unavailabilities and frequencies, calculating other system parameters, and modularising fault trees. Workshopped examples.

Initiating and Enabling Events: Explains initiating and enabling events and the modification of expressions for calculating frequencies.

Importance Analysis: Explains importance analysis and details methods including Fussell-Vesely, Birnbaum, Barlow-Proschan and Sequential Importance. Workshopped examples.

Common Cause Failures: Explains common cause failures and details calculation models including Beta Factor, Multiple Greek Letter, Alpha Factor, and Beta Binomial Failure Rate. Workshopped examples.

House Events: Explains house events and how to use them to temporarily re-configure fault trees or to enable a single fault tree to represent a number of different operational phases.

Non-Coherent Fault Trees: Explains non-coherent fault trees and the use of NOT gates and Exclusive OR gates.
