A previously published computer program is used as a model in this pap
er to deal with a reliability and replacement problem from a Published
article. The problem of interest is to determine the reliabilities an
d the replacements simultaneously. The minimization of the objective f
unction used in this problem corresponds to the maximization of the mi
ssion reliability. Presented here are solutions slightly better than t
he solution given in the original article. Modelled after a published
computer program, the complete computer program and the first Part of
its output are included in this paper. This BASIC computer program as
is can be run on IBM-compatible personal computers with or without com
pilers.
