Fault Tree Analysis (FTA) is a top-down, deductive system safety analysis method used to identify the possible causes of a specific undesirable event (called a Top Event) in a system.

Usage of Module

•  To analyze the causes of system failures and assess their probability, helping improve system safety and reliability.

• Starts with the Top Event  and works backward to identify all basic events that could cause it.

• The fault tree is a logic diagram using symbols (e.g., AND/OR gates) to show relationships between events.

• Quantitative or Qualitative:

  • Qualitative: Identifies root causes and failure paths.

  • Quantitative: Calculates the probability of failure using basic event failure rates.

• Applications: Widely used in aerospace, automotive (ISO 26262), nuclear, oil & gas, medical devices, and more.

ARE YOU FACING ANY OF THESE PROBLEMS:

• System safety
• Risk Assessment
• Unable to indefity the root cause analysis
• Unable to find out the critical system/components

HOW SIMCAD CAN HELP:

• Identifies critical failure paths.

• Supports risk mitigation and design improvements.

• Provides input to safety cases and risk assessments.
