多阶段决策算子法在串联工程大系统优化中的应用

Multistage Decision Operator Technique Applied to Optimization of Large Scale Series Engineering System

应用多阶段决策算子法 ,讨论了串联工程大系统的优化问题 ,给出了两种情况下工程大系统最优可靠度的决策方法 :( 1)在给定总系统可靠度条件下 ,使系统总造价和损失期望之和最小 ;( 2 )在给定总系统造价和损失期望之和情况下 ,使系统可靠度最大。算例表明 ,文中提出的方法简便。

By the multistage decision operator technique,the optimization of large scale series engineering system is discussed and the decision method for the optimal reliabilities of large scale engineering system is given under two cases:(1)The sum of total construction cost and loss expectation is minimized under predetermined reliability of the engineering system.(2)The reliability is maximized under given sum of total cost and loss expectation.The numerical examples show that the presented method is simple and efficient.
