04 Common Distributions & Weibull Distribution

Module 2 Probability & Reliability Statistics

Lesson M02-04

Text: Section 3 pages 13 – 29

Duration: xx minutes

When analyzing non-repairable systems or components, we typically find probability distributions that best describe/fit the available time-to-failure data.  This lesson introduces some of the common models (distributions) used in practice.  Although the Weibull model is emphasized somewhat due to its popularity and convenient properties, we should also consider alternate models when estimating reliability statistics.
