System Safety Analysis

(SSA)

30 May 2007

 

 

Course Description

 

This is a course in the practical application of system safety and reliability analysis tools and techniques.  It addresses in methods suggested by MIL-STD 882D and SAE ARP 4761 for safety assessment.  These include Hazard Analysis, FMECA, Fault Tree, Human Factors Analysis and Common Cause Analysis.

 

Who Should Attend

 

  • Any safety analyst/engineer or reliability engineer whose success depends on your ability to quantify and evaluate risk in the design process.

  • Any one who wishes a better understanding of FTA fundamentals and receive feedback from an experienced practitioner/instructor.

  • Managers of safety/reliability engineers who need to understand the methods available to improve system safety and reliability.

  • Those responsible for implementing the design review and/or reliability process.

 

How You Will Benefit

 

  • You will enhance your ability to identify and evaluate hazards early in the design and development process.

  • You will be able you to understand and explore how to use and apply quantitative and analytical methods.

  • Presentations are supplemented with case studies and problem solving to encourage understanding of the mathematical models which form the foundation for risk assessment and reliability analysis.
