SIS PFD – Safety Instrumented System
The probability of Failure on Demand (PFD) calculation is carried out as part of the Safety Instrumented System (SIS) design after the LOPA/PHA study.
PFD
Probability of Failure on Demand (PFD)
Reliability, as previously defined, is the probability a component or system will perform as designed. Like all probability values, reliability
