| 摘 要： | 多阶段任务系统是一类普遍存在的复杂系统,研究其可靠性冗余优化对于该类系统设计具有重要的参考价值。针对多阶段任务系统的可靠性并联冗余优化问题,提出了采用冗余故障树和冗余BDD来描述系统冗余结构的方法。给出了冗余模块在多阶段任务系统中的可靠度计算方法,建立了整个冗余多阶段任务系统可靠度计算模型。在此基础上以费用最小为目标,构建多阶段任务系统可靠性冗余优化模型,并应用微粒群算法对模型进行求解。算例验证了模型的合理性及算法的有效性。 |

| Abstract: | Phased-mission system is a kind of broad exist complex system.The research of reliability optimization has important reference value for this kind of system. For reliability parallel redundancy optimization problem of phased-mission systems,a method is proposed for the redundancy fault tree and redundancy BDD to describe system’s redundancy structure.The reliability compute method of redundancy module in phased-mission systems is given,and it put forward the reliability compute model of the whole redundancy phased-mission systems.On this basis to build reliability redundancy optimization model of phased-mission systems by taken minimum cost as objective,and used particle swarm optimization to solve the model.The case validates the model’s rationality and the arithmetic’s validity. |
| Keywords: | phased-mission systems redundancy optimization BDD particle swarm optimization |
