摘要
假定修理设备的失效分布为指数分布,一个部件的失效分布为Erlang分布,另一个部件的失效分布、两部件的维修分布和修理设备的更换时间分布均为连续型分布.利用补充变量法求得了修理设备可更换两部件串联可修系统的全部可靠性指标.
In this paper, a typical two-unit series repairable model of changeable repair facility is discussed. In the model, failure distribution of repair facility is assumed to be exponential distribution, failure distribution of one unit to be Erlang and other four distribution to be continuous. By using the supplementary variable method, explicit expressions are derived for the laplace transform of all reliability specifications of the system.
