摘要
针对目前可靠度分配方法中忽略了损失费用与可靠度之间的函数关系的问题,分析给出了损失费用与机械产品可靠度之间的函数关系。以机械产品的成本最小、损失期望最小及期望收益最大为目标,建立了基于投资—效益准则的机械系统可靠度分配的优化模型,最后给出的算例证明了方法的有效性。
Aimed at the function relationship between damage cost and reliability that is ignored in recently optimal allocation of system reliability, it derived this function relationship. Based on cost-benefit criterion and optimal allocation model of mechanical system reliability, the target functions were minimum for mechanical product cost, expectation of failure cost and expectation of benefit. A numerical example was given to illustrate the effectiveness of the method.
