n个部件和开关组成的时序转换系统的可靠性

Reliability analysis of time-ordered transformation system with n-components and a switch

针对一些部件交替工作的复杂系统的可靠性指标求解问题,给出了由n个部件和一个开关组成的时序转换系统的定义,并对此类转换系统的可靠性进行研究。当转换系统中的部件和开关的寿命都服从指数分布时,得到了转换系统的可靠度解析式,并将结果应用于空调的可靠度求解,在实践中检验结果的合理性。

To calculate the reliability of complex system with components alternatively working,the definition of time-ordered transformation system consisting of n-components and a switch was given in this paper.The reliability of the system was discussed accordingly.Suppose that the lifetime of the components and switch in the system were subj ect to some exponential distributions,we got the analytical expression of the systematical reliability.Furthermore,the reliability of air conditioner was calculated as well,based on our results,and the rationality of the results was tested through practice.
