文摘In this paper, we consider a transfer line with two unreliable machines and a single storage buffer, in which the second machine’s processing time and repair time have general distributions, and a piece processed by machine i will be reprocessed with probability q i (i=1, 2) because of uncompletely or not very well processed just before. At first, the exactly results of the reprocessed rate, the output rate and the blocked probability of machine 1, the reprocessed rate and the starved probability of machine 2, and the production rate of the system, are obtained when the first machine is reliable. And then, some approximating results of above indices are given when two machines are both unreliable.
