MIL-STD-781C and Confidence Intervals on Mean Time Between Failures.

ADA069966

Publication Date	1979
Personal Author	Schmee, J.
Page Count	49
Abstract	Various realistic examples illustrate how to obtain confidence limits on the mean time between failures (MTBF) of an exponential distribution from data obtained from one of the fixed-size or sequential test plans of MIL-STD-871C. For fixed-length tests, the methods developed by B. Epstein and the modifications of H. L. Harter are briefly discussed. For the sequential tests simple charts for newly developed methods of Bryant and Schmee are given. (Author)
