非串—並聯系統可靠性最優分配問題是一個具有多局部極值的非線性優化問題。使用遺傳算法求解該問題搜索到了其他算法未能得到的最優解,在遺傳算法的應用中,使用基于排名的選擇策略和最優保存策略,改善了遺傳算法的收斂性能。
An optimal apportionment of reliability problem of non serial-parallel systemis a nonlinear optimization problem with a large number of local extreme values.It is very difficult for traditional optimization techniques to search the global ornearly global optimal solution of such a problem.Here,genetic algorithm isadopted to solve the reliability optimization allocation problem,and obtains amore optimal solution than other algorithms.In the application of GA,rankingselection strategy and optimal preservation strategy are adopted,which improvethe convergence performance of GA.
