2 Day Comprehensive FaultTree+ Workshop

The course instructors have extensive experience in providing systems reliability training world-wide. Summary details for our popular Fault Tree Analysis Workshop are given below (workshop sessions are based on the FaultTree+ computer program):

• Introduction. System unavailability, unreliability and failure frequency, concept of risk, F-N curves.
• Fault Tree Construction. System and component events, construction rules, 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.
• Basic Probability Theory. Independence and exclusivity, addition law, multiplication law.
• Component Failure and Repair Models. Failure rate, constant failure and repair rate model, dormant failure model, application within a fault tree study.
• System Quantification. Calculating cut set unavailability and failure frequency, calculating TOP event unavailability and failure frequency, deriving other system parameters, modular fault trees.
• Initiating and Enabling Events. Addressing the sequence in which events can occur.
• Importance Analysis. Fussell-Vesely Importance, Birnbaum Importance, Barlow-Proschan Importance, Sequential Importance.
• Confidence Analysis. Taking account of uncertainties in failure data.
• Common Cause Failures. Common cause failure categories, applying the Beta Factor method.
• House Events. Re-configuring the fault tree, examining preventive maintenance options, real-time availability assessments.
• Non-Coherent Fault Trees. How to manage trees with NOT and EXCLUSIVE OR logic, Boolean algebra rules, computational options.
• Event Tree Analysis. Constructing an event tree, analysis methods, quantifying consequences, F-N curves.
