系统可靠性优化的离散多目标决策方法

Multi-Objective Decison-Making Method for System Reliability Optimization with Discrete Variables

工程实际中 ,人们往往在追求系统的可靠性达到最大的基础上 ,又追求系统的造价到达最小。另外 ,系统中单元的可靠性有时需从给定的离散集中选取。针对上述现象 ,提出了离散多目标决策方法 ,用于选取大型复杂系统中单元可靠性的最优值。

In practical engineering, on the one hand it is usually expected that the system's reliability attains the maximum at the minimum cost, on the other hand each unit's reliability is often constrained by a discrete set. To solve the above problem, a multi objective decision making method with discrete variables is presented. Many examples prove that the algorithm is very effective. \;
