Analytical determination of reliability of a complex system is item dependent and setup dependent and a very
difficult task. In this paper we propose reliability approximation based on reliability bounds for one such
engineering item - a Resistor with independent components having the Weibull distribution. Earlier approach for
reliability approximation was discretization. We provide a different approach for reliability approximation so that
one not only gets a clear idea about the extent of error but also can adjust reliability in terms of distributional
parameters. This reliability approximation having the Weibull distribution can be of practical use and importance
as reliability approximation is developed in terms of distributional parameters.
