摘要: Abstract We are interested in the MUT (Mean Up Time) of a one out two system cold standby with preventive maintenance: maintenance occurs when working unit reaches given age. study details stationary distribution Markov chain describing state at beginning its periods. give exact analytical formulas from which we derive way to compute and compare results those Smith Decker [M.A.J. Smith, R. Decker, Preventive 1 n system: The uptime, downtime costs, European Journal Operational Research 99 (1997) 565–583] based on approximations. also investigate some discontinuities problems.
