| Abstract: | This paper deals with a two-dependent-unit parallel system where the repair facility is subject to failure and canbee replaced by a new one after it fails.Assume that the life lengthes of the two units obey a bivariate exponential distribution and the life length of the repair facility has an exponential distribution.The repair time and the repla- cement time of the facility are assumed to be arbitrary.By using Markov renewal theory,the reliability quantities of the system and the repair facility are obtained,respectively. |
