Incorporate quantitative Human Factors into a SIL analysis. Representative operating units at various stages of maturity in human factors an

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

Functional Safety Specialists May be Stuck in the Past – Do our SIL calculations Reflect Reality?

Functional safety specialists may be stuck in the past and doing industry a disservice. The current industry trend is to only consider rando

The use of Bayesian Networks in Functional Safety

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