【Abstract】 In this paper, the optimal planning problem for the selection and the redundancy of components of system is investigated. The formulation for integrated reliability-based design optimization problem for components ’selection and redundancy planning under the constraints on cost and weight of system is given, and the genetic algorithm (GA) is employed to solve this problem. The optimal planning of the selection and the redundancy of components for a serial-parallel mixed system is made. The results show that the model and the method are reliable and effective.更多还原
