摘要
本文给出了二种情况下串联工程系统各结构最优可靠度的决策方法:一种情况是在给定总系统可靠度条件下,使工程总造价和损失期望之和最小;另一情况是在给定总造价和损失期望条件下,使总系统可靠度最大.这是相互对偶的二个问题.本文所提的方法比我们在文献[1]中提出的工程系统全局优化方法更为合理,具有更大的应用价值,并且在计算上也更为简便.
In this paper,the decision method for the optimal reliabilities of the structureswhich are contained in a series engineering system is given in two kinds of cases.Inthe first case the total construction cost and loss expectation is miximized underpredetermined reliability of the engineering system.In the other case the reliability isoptimized under the condition that the total cost and loss expectation are given.They are dual problems in mathematical programming.The present mothod ismore reasonable than the one given in [1],and it is also more applicable andeasy to used.
