A method of distribution and optimization of reliability of complex systems was presented. The problem of distribution and optimization of reliability complex systems which were constructed on component level was reduced to the problem of nonlinear programming by building practical cost-reliability function and nonlinear programming model considering the effect of cost in the distribution and optimization of reliability. In order to gain feasible numerical solution in the nonlinear programming problem, an improved genetic algorithm having self-adaptation function was proposed. By using this method, distribution and optimization of reliability of more complex system can be solved.
