摘　　要：针对复杂系统可靠性的冗余设计问题,从产品设计角度出发,证明了在系统组成单元中对可靠度最低并且初始冗余数最少的部件增加冗余设计使得系统总体可靠性水平的提高最快,给出了寻优计算算法,根据相关约束设计了方案筛选实验。以典型串并联系统为例,利用Anylogic仿真平台对求解过程进行了仿真实现,得到了系统最佳冗余设计方案,验证了方法的合理性和有效性。For the redundancy question of complex system reliability design, from the angle of product design, on the basis of sensitivity analysis of different design program, it has be proved to add redundancy design for subsystem with lower reliability and less redundancy will enhance the probability of reliability more for complex system. On the foundation of above research, the program screening simulation experiment was designed according the related restraint and optimization algorithm for redundancy design was proposed. An example of series-parallel connection system was given, obtaining the optimization design program based on Anylogic software to prove the rationality and effectiveness of the method.
