摘　　要：提出并讨论了以下命题:对串联可修系统,系统稳态可用度等于各部件稳态可用度乘积;对并联可修系统,系统稳态不可用度等于各部件稳态不可用度乘积。基于 n 个不同部件串联可修系统和三个不同部件的并联可修系统模型,对上述命题进行了证明并确认了其适用范围,对多部件串联系统,一个修理工,考虑多部件同时故障的概率;对多部件并联系统,修理工数目与部件数目相等。最后尝试将该命题推广到可修系统瞬态可用度的计算,并举例进行了对比。Based on markov process,the proposition is put forward that steady state availability of series system is equal to the product of steady state availability of all units;steady state unavailability of parallel system is equal the product of steady state unavailability of all units.It has been proved for series system of n units and parallel system of 3 units.It is applicable to a series system of multi-units with a repairman and a parallel system of multi-units with repairmen that the unmber of them is same as that of units.It has been discussed that the proposition is extended for determining tran- sient state availability of repairable system.
