Abstract

MTBF (Mean Time between Failure) is perhaps the most common indicator for reliability level used in the industries. This paper examines the statistical foundation of this indicator and investigates the limitation and risk of using it. Examples are provided to demonstrate the errors when misusing the MTBF. The examination is not trivial if the error is found significant. Some misconceptions on the MTBF are also discussed to raise the awareness of using this indicator correctly in the paper. Furthermore, the paper points out some results from the demonstration in the paper might be opposite to our intuition. Industrial engineers should avoid to make decision according to those unverified intuition. Upon the limitation and problems, the paper furthermore proposes some approaches to mitigate the limitation and the problem of the use of the MTBF.
