摘要
为了提高系统可靠性,可以把多个相同的部件并联起来,共同降额使用,构成共载并联系统,这种办法极为有效而又简单易行。在对这种系统进行可靠性分析时,通常假设各个部件之间是独立的,但实际上,各个部件之间并不是独立的。根据这种情况,建立了两个高可靠性不独立共载并联系统的模型,进行了可靠性分析,并在失效时间服从指数分布的假设下计算出了系统的可靠度。
In this article, we study two models for unrepairable and repairable parallel system with n same dependent units. In the model for unrepairable parallel system, we obtain the expression of the reliability of the system. In the model for repairable parallel system, we give the steady results of the reliability. In addition, we study one example and successfully obtain the numerical value of the system reliability. This numerical result shows that the models in this paper are useful for calculating the reliability of practical parallel system.
