mean availability
1.In this paper, on the basis of the analysis method of the net list graph, we present a method for calculating the forward or backward link reliability of the net list graph to solve the reliability problem of dual ring net, and solve respectively reliability, mean time between failure (MTBF) and availability of dual ring netwith the different skip distance (8) in the light ofBoolean algebra.
2.In this paper, a n-unit series repairable system with delay repair is studied,assuming that the systematic unit?s life has exponential distribution, the dalay repair time and the repair time both have general distribution,some primary reliabilities indexes are obtained by using renewal process theory, such as reliability R(t), availability A, the mean time to first failure MTTFF and the mean times to failure of the system during (0,t],etc.
