Fault Tree Analysis
Fault Tree Analysis (FTA) - is a graphical technique for Reliability and Safety Analysis of Systems. It is used:
a. to investigate potential faults.
b. its mode and causes and
c. quantify their contribution to system unreliability in the course of product design.
The basic constructs in a fault tree diagram are gates (conditions) and events (causes leading to failure).
Fault tree diagrams are logic block diagrams that display the state of a system (top event) in terms of the states of its components (basic or lower level events) using Boolean logic.
