A general methodology, based on algorithms developed by the Ad-Hoc Methodology Working Group on Nuclear Weapons Reliability Assessment, is described for evaluating 90 lower confidence bounds on system reliability for configurations of seriesparallel circuits. General configurations of non- repeated and repeated components are examined and a method for unpooling data is discussed. A technique is derived for representing m out of n decision logic gates. The methodology is applied to an example of the type of a sophisticated weapon fuzing system. Maximum likelihood estimates of reliability and 90 lower confidence bounds are calculated for the system and critical components are identified.
