摘要
复杂系统通常具有单元多 ,可靠度为非凸函数的特点 ,其冗余优化设计难度较大。为此 ,本文提出了一种新的冗余优化方法 ,即平衡优化方法。引入了平衡态、平衡优化的概念 ,说明了该方法的原理和数值算法 ,并通过举例与现有的方法进行了比较。
Since a complex system characterizes as multi component and unconvex reliability function, the optimization of its redundancy is very difficult. This paper develops a new algorithm method for redundancy optimization in complex systems, i.e., a balance method. The concepts of balance status and balance optimization are introduced. The effectiveness of the method is tested with an example of a bridge system.
