Abstract

In this paper, we solve the problem of finding interval estimate for system reliability via
the CHA algorithm (Chaudhuri et al., 2001) following the Easterling (1972) approach. We
consider a coherent system composed of independent components. No distributional assumption
is made for the component life times. A closed form expression for the standard
error of the system reliability, for a given mission of duration, is obtained. The method of
calculating the 100(1
