In this paper, we solve the problem of finding interval estimate for system reliability via
\nthe CHA algorithm (Chaudhuri et al., 2001) following the Easterling (1972) approach. We
\nconsider a coherent system composed of independent components. No distributional assumption
\nis made for the component life times. A closed form expression for the standard
\nerror of the system reliability, for a given mission of duration, is obtained. The method of
\ncalculating the lower confidence limit for the system reliability is illustrated
\nfor a simple low-pressure coolant injection system (LPCI) with two pumps (Blischke and
\nMurthy, 2000). Both the CHA algorithm and the usual variance method are used for calculations.
\nSome simulation results are also reported. This paper basically extends the results
\nof Easterling to any coherent system.<\/p>\n
