稳态不可用度 meaning in English

steady-state unavailability

In this paper , the repairable queuing system with police is studied . some important queuing quantities and reliability quantities are in detail discussed as follows : ( 1 ) using the renewal process theory and the method of stochastic decomposition , both the transient and equilibrium distributions of the queue length from any state are discussed , and the recursion expression of the equilibrium distribution is given by furthermore , the generating function of equilibrium queuing length distribution is given by ( 2 ) the distribution of waiting time is discussed , and the mean waiting time is given by ( 3 ) the departure of the system is discussed , and the mean value of departure customers when is given by
具体如下： ( 1 )利用更新过程理论和随机分解方法,讨论了从任意初始状态出发队长分布的瞬态解和稳态解,得到了队长平稳分布的递推公式：并进一步求得了系统的稳态队长分布的母函数( 2 )讨论了稳态等待时间分布,求得了平均等待时间： ( 3 )讨论了系统的输出过程，求得了长期单位时间内离去顾客的平均数： ( 4 )讨论了服务台的不可用度，得到了稳态不可用度: ( 5 )讨论了内服务台平均故障次数，求得了长期单位时间内的平均故障次数
