摘要
可靠性设计优化由于考虑了实际中广泛存在的不确定性信息而受到研究者的广泛重视,同时在提高产品可靠性和服役性能方面发挥了重要作用,因此一直是工程设计领域的研究热点之一。围绕概率解析和代理模型两个方面,面向随机不确定性场景,系统梳理和综述了可靠性设计优化领域的重要研究进展,并总结了时变可靠性设计优化的重要成果。探讨了可靠性设计优化所面临的问题和挑战,展望了未来的发展趋势。
Reliability-based design optimizationhas gained much attention due to the ability of considering the various uncertainty informations.Since reliability-based design optimization played a significant role in the improvement of product reliability and other performances in the full life cycle,it is one of the most popular research topics in the field of engineering design.The state-of-the-art achievements and contributions in the field of the reliability-based design optimization as well as the time-dependent reliability-based design optimization under aleatory uncertainties were reviewed from the perspectives of analytical strategies and surrogate models.Moreover,the existing problems and challenges were discussed,and some research directions in future were concluded.
