Using the Weibull Distribution to Understand Component Reliability
Component Reliability Analysis Much of our work involves determining the reliability of components, where we want to understand how long they will last before failure. We use statistical analysis to predict these failures in terms of the expected number of hours used, miles driven, etc. Say we are given data on vehicle components and how […]
