    Abstract
  • An availability analysis method for repairable system i.e. Dynamic Fault Tree Analysis(DFTA) was presented .To achieve high reliability and availability, redundant hardware and fault-tolerant software associated with dynamic process, time sequence, backup and failure recovery were adopted in the computer control system. Combing DFTA method and Markov model for repairable system, the dynamic process of a fault-tolerant system and the repairable process can be easily described. To calculate the equivalent failure rate, recovery rate and availability of top event of a complicated system, it is necessary to divide the system into several subtrees which can treated with Markov model. Recurrent, the availability parametes from top to down can achieve the availability analysis for the complicated system.
