![]() Its formula can is represented as:Īccording to the results, the series system overall reliability was 51.11%. The reliability of a serial system consists in the product of its individual components reliabilities. Step #4: Obtain probabilities - Obtain the probability of failure before a time t using the cumulative density function and the reliability after a time t using the survival function.Step #3: Obtain the distribution parameters - Obtain the location, scale and additional parameters for the selected distribution to determine its probability density function, cumulative distribution function and survival function.Step #2: Identify the distribution that best fits the data - Based on a histogram from the collected data, fit multiple probability distributions and identify the one that best describes the data.Step #1: Obtain failure times - Define a sample size and obtain the functional time for each component until its failure.The steps required to calculate a component reliability for a specific time are as follow: Where f( t) is the probability density function of the given distribution.
