Web8 System Reliability: Preliminaries The Reliability, RF(t)of a System is the probability that no fault of the class F occurs (i.e. system survives) during time t. RF(t)= Pr[tinit≤ t < tffor all f ∈ F] where tinit is time of introduction of the system to service tfis time of occurrence of the first failure fdrawn from F Failure Probability,QF(t)is complementary toRF(t) WebThe hardware fault tolerance (HFT) of a safety system of N (either 0, 1, or 2) means that N+1 is the minimum number of faults that can lead to the loss of the safety function. If the hardware’s HFT = 1, the system maintains the safety function if one fault occurs. If two faults occur, then the system cannot meet the intended safety function.
