【摘要】 本文研究了在总费用指标约束下串联机械系统可靠度的优化分配问题,提出了以系统的损失期望最小化为目标函数的优化模型。该模型与以系统的总可靠度最大化为目标函数的优化模型相比,在一般情况下更为合理,而在某些特殊的情况下二者是一致的,因此本文所提优化模型更具普遍意义。更多还原

【Abstract】 This paper discusses optimum reliability allocation problem in series mechanicalsystems subject to the constraint under the index of overall cost. The optimization model using loss expectation minimization of the system as objective function is presented. In general cases, the model is more reasonable than the one using system reliability maximization as objective function, and in some special cases, both are identical, and therefore the former is of more unniversal significance.更多还原
