WebbThis function gives the probability of an item operating for a certain amount of time without failure. As such, the reliability function is a function of time, in that every reliability value has an associated time value. In other words, one must specify a time value with the desired reliability value, i.e. 95% reliability at 100 hours. Webb1.2 Failure Rate and Probability of Failure Bathtub curve The reciprocal value of the MTBF that is a measure for the reliability of a component is the failure rate λ. Plotting of the statistical failure rate λ over time t gives the bathtub function shown below (bathtub curve). Failure rate Failure rates have the dimension of 1/time unit.

WebbHowever, if the corrective action is not 100% effective, then the method above cannot be used to estimate reliability. In Synthesis Version 10, Weibull++ standard folios can perform fractional failure analysis, where one can account for the effectiveness of an assumed corrective action or product redesign in the analysis.
