【摘要】 系统的可靠性设计中经常使用的混合冗余备份策略可以提高系统的可靠性,温备份元件的转化通常在上一个热备份模式的元件失效后立即转化替换;在延迟转换混合备用系统中,经过一定的延迟时间后才会替换前一个备份元件,这些元件的初始化分布对系统可靠性和任务成本有较大影响。首次使用粒子群算法来处理这种可靠性系统的组合优化问题,找出最优元件排序组合和最佳延迟时间;通过这种算法处理找出的元件排序组合可以经济有效地应用于系统可靠性设计中。更多还原

【Abstract】 The reliability of the system is often used in the design of hybrid redundancy backup strategy, which can improve the reliability of the system. The transformation of warm backup element is usually immediately happened after a last hot backup mode component failure. In the delayed transformation hybrid backup systems, the new component will replace the previous backup components after a certain delay time. The initialize distribution of these components has a great influence on system reliability and task cost. Uses particle swarm opti-mization(PSO) algorithm for the first time to deal with this kind of system reliability of combinatorial optimization problem and find the optimal combination and the optimal delay time. The element combination through this algorithm processing can efficiently applied to the design of system reliability.更多还原
