Challenging Safety Metrics in Process Industries: A Bayesian Perspective on Layer of Protection Analysis (LOPA)

The process industry uses Layer Of Protection Analysis (LOPA) to document extremely small probabilities for catastrophic events....

Does Your Facility Have the Flu? Use Bayes Rule to Treat the Problem Instead of the Symptom

Is our industry addressing the problems facing it today? We idealize infinitesimally small event rates for highly catastrophic hazards,...

The use of Bayesian Networks in Functional Safety - Whitepaper

Functional safety engineers follow the ISA/IEC 61511 standard and perform calculations based on random hardware failures. These result in...

What is Truth? Do SIL Calculations Reflect Reality?

Are random hardware failures the only thing that cause a safety instrumented function (SIF) to fail? What if our assumptions are wrong? What
