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 problem of redundant design of complex system reliability, from the viewpoint of product design, it is proved that adding redundant design to the system component unit with the components with the lowest reliability and the lowest initial redundancy makes the overall system reliability level increase fastest , Gives the optimization calculation algorithm, and designs the scheme screening experiment according to the related constraints. Taking the typical series-parallel system as an example, the simulation process is simulated by Anylogic simulation platform, and the optimal redundancy scheme of the system is obtained, which proves the rationality and effectiveness of the method.
