| 中文摘要 |
| 基于目前装备系统中存在的新装备在投入使用初期出现瞬时可用度剧烈波动的现象, 分析了离散时间下单部件可修系统的瞬时可用度模型, 提出了可用度振幅的概念用以刻画这种系统瞬时可用度波动. 在此基础上, 建立了关于可用度波动振幅的最优模型. 然后针对装备工程大量存在离散Weibull分布的假定, 用粒子群算法解决了系统可用度最小波动的设计问题, 并用两组算例对最优设计模型的有效性给予了验证说明. |
| 英文摘要 |
| Based on the variation of instantaneous availability of new equipment in its early stage of application, we study the instantaneous availability model for a system with repairable assembly parts at discrete-time instances, and propose
the concept of availability amplitude to characterize the instantaneous availability variation of this system. On this basis, the optimal model of the availability amplitude for the system is built. The particle-swarm method is applied to minimize the availability variation of this system under the assumption of discrete Weibull distribution which is abundant in equipment engineering. Finally, two examples are given to illustrate the effectiveness of the proposed model. |
