exida Presenting at System Safety and Cyber Security 2015
October 19, 2015
Iwan van Beurden, exida Chief Technology Officer will be presenting at the System Safety and Cyber Security 2015, to be held October 20-22, 2015 in Bristol, UK.
The presentation is titled: Predictive Analytics: Using Field Failure Data to Predict Failure Rates for SIS Verification.
Performance based functional safety standards like IEC 61511 offer many advantages including the opportunity to optimize and upgrade Safety Instrumented Functions (SIFs) designs. Performance calculations depend on realistic failure data for instruments used in SIFs. A predictive analytics technique based around the Failure Modes Effects and Diagnostic Analysis (FMEDA) has been developed along with a component failure rate database that can predict failure rates of instruments based on their design strength and the expected stress environment. This method has been calibrated with over 150 billion unit operating hours of field failure data over the last 15 years. This paper will discuss field failure data sources, the calibration of the predictive analytics methodology, and a comparison of collected field failure data with FMEDA predicted failure data.
