WebThe 1-parameter exponential reliability function starts at the value of 100% at =, decreases thereafter monotonically and is convex. The 2-parameter exponential reliability function remains at the value of … WebThus, at a constant rate of failure, h ( t) = λ. (6.26) The above equation indicates that the reliability R ( t) of a product under a constant rate of failure, λ, is an exponential function of time in which product reliability decreases exponentially with the passing of time. The parameter λ is related to the mean time between failures, T ...
