该文研究两个修理工的M/M/2可修排队系统,系统有两个相同的服务台,服务台忙时与闲时故障率不同.文中给出系统的稳态状态概率,系统的稳态可用度及系统的稳态平均队长,并给出系统稳态概率存在的条件.
In this paper, we consider the M/M/2 queueing system with service interruptions. The rates of server breakdown are different between busy time and idle time,and there are two repairmen in the system. We obtain the steady-state probabilities of the states, the steadystate availability and the steady-state queueing length, give the condition for the existence of the steady-state probabilities.
