本文首次从系统可靠性的角度研究多级适应性延误休假M^x/G/(M/G)/1可修排队系统,讨论了服务台如下的一些可靠性问题:(1)在时刻t失效的概率;(2)在服务员忙期内失效的次数;(3)在[0,t]内的平均失效次数;(4)在服务员忙期内的失效时间.
In This paper we firstly study the MX/G(M/G)/1 repairable queueing model with adaptive multistage delay vacation from the angle of reliability and discuss the following reliability problems of the service station: (1) The probability that it fails at time t; (2) The failure number during the server busy period; (3) The expected failure number during [0, t] ; (4) The downtime during the server busy period.
