WebFigure 1. Failure rate (dotted lines) and percent remaining (solid lines) versus time for two hypothetical products. Reliability is the rate of random failure during the useful life phase, which is slightly lower (better) for the product shown in red. Using a 50% remaining metric for determining lifetime, the blue product has a longer rated life. WebA beta equal to 1 models a constant failure rate, as in the normal life period. And a beta greater than 1 models an increasing failure rate, as during wear-out. There are several ways to view this distribution, including probability plots, survival plots and failure rate versus time plots. The bathtub curve is a failure rate vs. time plot. simon\\u0027s cat birthday ecard
