Introduction:

Fault tree analysis is a logical, structured process that can help identify potential causes of system failure before the failures actually occur.  Fault trees are powerful design tools that can help ensure that product performance objectives are met.   Sandia has a tremendous depth and breadth of experience in applying fault tree analysis to analyze system safety and reliability.  Fault tree applications at Sandia include manufacturing equipment, automotive subsystems, aircraft,  nuclear  power plants, and weapons systems.

Benefits:

• Identify possible system reliability or safety problems at design time,
• Assess system reliability or safety during operation,
• Improve understanding of the system,
• Identify components that may need testing or more rigorous quality assurance scrutiny, and
• Identify root causes of equipment failures.

 Capabilities:

• Fault tree analysis and failure modes and effects analysis,
• Design for reliability,
• Design for safety.
