摘　　要：针对桥式网络系统,提出子系统可靠度指标和冗余个数一体化并发设计问题,并建立优化模型,将Matlab遗传算法应用于复杂系统可靠度和冗余数的最优分配这类非线性连续变量和离散变量混合问题的求解,为实际问题中的网络系统提供设计方法,最后通过算例结果验证该模型的有效性和实用性.For bridge network system,the integration of concurrent design problems of subsystem＇s reliability index and the number of redundant was raised and the corresponding optimization model was established.Matlab genetic algorithm was applied to complex system optimal allocation of reliability and redundancy which was a mixed problem of nonlinear continuous variable and discrete variable to provide a design method for the network system in the actual problem.Finally,the example results verified the effectiveness and practicality of the model.
