Abstract : In the paper, methods of obtaining lower confidence bounds on the reliability of non-maintained systems are surveyed, and numerical comparisons are given. It is assumed that failure data have been collected from life tests performed on prototypes of the various subsystems which make up the system, but that the system has not been tested as a whole, for some particular reason. The reason may be, for example, expense or simply that it is virtually impossible to test the entire system without destroying it. Methods applicable to series and/or parallel and more logically complex systems are discussed. (Author)
