This paper is concerned with maximizing a system reliability function
subject to nonlinear constraints. Numerical examples from the literatu
re are handled by a general nonlinear programming algorithm, which can
deal with the positive-integer variables of this reliability problem
without special difficulties. The computational results presented in t
his paper suggest that the computer program listed here can be useful
as a model for maximizing the system reliability function subject to t
he nonlinear constraints used here. In addition, because of the genera
l applicability of the nonlinear programming algorithm, other system r
eliability functions and nonlinear constraints different from the ones
used in this paper can also be accommodated.
