| 摘 要： | 针对船舶系统可靠性设计问题,采用改进非支配排序遗传算法(NSGA Ⅱ)研究了可靠性指标分配中的多目标优化设计.根据Pareto最优解集形成决策矩阵,基于信息熵法得到属性权重,利用逼近理想解的排序方法(TOPSIS)进行多属性决策研究.对Pareto最优解给出排序.采用本文方法讨论了一个船舶系统可靠度的分配和预测算例,给出了可靠度和费用之间的拟合关系.数值算例表明,综合采用多目标优化和多属性决策技术,可以迅速、客观选择各部件的可靠度.这种综合方法还能用于可靠性研究的其他领域.

| Abstract: | Multi-objective optimization and multi-attribute decision making study of reliability allocation is evaluated in present study.A hybrid approach is proposed for reliability optimization.In the first stage,a Non-dominated Sorting Genetic Algorithm II(NSGA II)is employed to approximate the set of Pareto solution through an evolutionary optimization process.In the subsequent stage,a multi-attribute decision making(MADM)approach is adopted to rank these solutions from best to worst and to determine the best sol... |
