A reliability optimization problem of multilevel serial systems and bridge network systems, with the constraints of cost, volume and weight, is a nonlinear mixed integer programming problem, which has a large number of local extreme values. GA is adopted to solve the system reliability optimization problem and a more optimal solution than other algorithms is obtained. In the application of GA, rank based model and elitist model are adopted, which improve the convergence performance of GA.
