Reliability Testing

Reliability testing is the cornerstone of a reliability engineering program. It provides the most detailed form of reliability data because the conditions under which the data are collected can be carefully controlled and monitored. Furthermore, reliability tests can be designed to uncover particular suspected failure modes and other problems. The type of reliability testing a product undergoes will change along different points of its life cycle, but the overriding goal is to insure that data from all or most of the tests were generated under similar enough conditions so that an "apples to apples" comparison can be made of the product's reliability characteristics at different points in the product's life. It is for this reason that consistent and thorough reliability specifications and a standard definition of failure are up-front requirements to implementing reliability testing.

Fielded Systems in Reliability Growth (Part II)

In last month's issue of the HotWire, we presented repairable system analysis for reliability growth in the article Fielded Systems in Reliability Growth (Part I). Fleet analysis will be presented in Part II of this article. Fleet analysis is similar to repairable system data analysis. However, the Power Law model is applied to the fleet failures rather than the system failures. In other words, in repairable system data analysis, the number of system failures versus system time is modeled. In fleet analysis, the number of fleet failures versus fleet time is modeled. Therefore, in both cases, the model is the same but the data are treated differently.
