The probability that the component will last more than 2,000 hours is 0.91 (cell B6). The mean of the Weibull distribution is the mean time to failure (MTTF) or mean time between failures (MTBF).įirst, we simplify the second equation and then we take the natural log of both sides of both equations to get. This happens if there is an aging process e.g. This might suggest random external events are causing mortality or failure. Maintain 95 of production so if there is 1 failure for Option A, we must repair immediately. The software performs life data analysis utilizing multiple lifetime distributions (including all forms of the Weibull distribution), with a clear and concise interface geared toward reliability engineering. The actual developer of the software is ReliaSoft Corporation.
