| Abstract: | In terms of the Laplace transform expressions of the system state probability this paper discusses the reliability for a one-unit repairable system with a replaceable repair facility and multiple delay vacations of a repairman.With the help of system analysis and comparisons some new reliability indices for the system and repair facility are derived as follows:(1) the probability that the system is waiting for repairing,renewal frequency and mean renewal time of the system,(2) generalized busy period length... |
