摘要
多态系统可靠性能够更加详细地描述复杂系统在不同性能水平下的可靠性,其优化问题研究促进了多态系统可靠性理论在工程中的应用。对多态系统可靠性优化的相关研究工作做了阶段性总结,并分析了今后该领域的发展趋势。从多态系统可靠性冗余分配优化、维修/冗余策略优化、部件位置优化、可靠性增强优化、多目标优化以及优化算法等六个方面分析了目前的研究情况,展望了今后在模糊多态系统可靠性优化、考虑相关失效的多态系统可靠性优化、RAMS+C多态系统可靠性优化等方面需要开展的研究工作。
Multi-state system reliability is very important for complex systems which have a range of performance levels from perfect functioning to complete failure. The research works on reliability optimization of multi-state system promote the applications of multi-state system reliability. The paper provides a broad overview of recent research on reliability optimization of multi-state system, and discusses the further research directions. In particular, six issues are analyzed： redundancy allocation problem, maintenance/ redundancy allocation problem, optimal allocation of elements, optimal reliability enhancement, muhi- objective optimization, and optimization algorithms. The further research can be focused on fuzzy reliability optimization, reliability optimization in the presence of dependent failure, reliability optimization based on RAMS ＋ C, and so on.
