Fault Tree Analyses (FTA)

The Fault Tree Analysis (FTA) is a qualitative or quantitative procedure that can be used to assess complex systems and failure events by looking at probability of occurrence and parameters of reliability and availability. The fault tree illustrates the cause and logic connections of failure events as a diagram.

Your benefit:

evidence of reliability/safety and availibility of mostly technical systems with the following factors taken into account: random external influences, operating conditions and maintenance
qualitative examination of structured systems
detection of weaknesses and hazards
systems assessment at an early stage, i.e. during development phase
successive systems design from the reliability perspective (including redundant features, change of reliability characteristics and inspection intervals…)
analysis in according with standards (DIN 25424/ IEC 61025/ IEC 61078)

For our analytical work we currently use a program called "SYSTEME". Other software can be applied at your discretion.
