摘要: |
可用度是衡量系统可靠性、维修性水平的一个重要指标。提出一类基于gamma劣化过程的可修串联系统的可用度计算方法。该方法从构成系统部件的状态出发,用gamma过程刻画部件的退化失效规律,同时考虑系统维修效果的不完全性,在此基础上推导出系统可用度的表达式。最后用一个算例验证了研究模型的合理性。 |

Abstract: |
Availability, as a scale of the reliability and maintainability level, is an important parameter of repairable system. A method of calculating system availability for series repairable system is studied in the current research. From the states of components, the methodology presented uses a gamma distribution to model the material degradation, and the impact of imperfect maintenance actions on the system reliability is investigated. At last, a numerical example is presented to demonstrate the use of the model. |
Keywords: repairable series system imperfect repair availability gamma process |
