Abstract

Abstract Four theoretical methods providing total system reliability bounds from sub-system test data are numerically compared through a simulation study. The methods in question, Kramer, El Bawazini-Buehler, Grubts and Mann-Grubbs, are compared with respect to the observed coverage of the true reliability as well as to the (empirical) form of their statistical distribution. The effects of several factors (pre-specified confidence level, system structure, truncation procedure) on the performance of these bounds are also studied. Finally, based upon the experimental results, recommendations are given as to which bound to use.
