Optimization Method of Reliability Allocation Based on Minimum CostGAO Jun-dong

摘要: 针对某型水下电视监视设备改型设计提出的要求, 利用专家分配法对该设备进行了可靠度分配, 提出了费用最小的最优化分配方法, 对设备各分系统的可靠度进行再排序和再分配, 并结合费用函数的约束, 得到了费用最优化条件下的分系统可靠度, 通过仿真分析验证了费用最优。此方法简单易行, 便于实际运用, 对水下产品改型设计中的可靠度分配工作具有借鉴作用。

Abstract: An optimization method of reliability allocation based on minimum cost is proposed by making use of the expert allocation method for the redesign of certain underwater television surveillance equipment. Considering the requirements of the redesign, the reliability of each subsystem is reordered and reallocated, and the reliabilities of the subsystems in the condition of minimum cost are achieved under the constraint of the cost function. Simulation result verifies the minimum cost. The proposed method is easy in practical application, and may facilitate reliability allocation in underwater product redesign
