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
Difference between Availability, Reliability & SIL
We often come across the above terms, and others, when we are talking about equipment and systems. All of them
