研究一类到达服从一阶离散自回归过程,服务器有可能中断的离散排队系统.着重考虑在到达流具有相关性的情况下,排队系统的性能表现.文章通过概率母函数的方法,得到了系统队长的概率母函数,并由此导出系统平均队长.最后通过数值实验可以看出系统的性能对到达过程的相关性非常敏感.
This paper considers a discrete-time queue with discrete autoregressive process of order 1 (DAR(1)) and server interruption. Close-form expressions for the prob- ability generating function and mean queue length are derived. Finally, some numerical results are given and it is shown that the system performance is quite sensitive to the correlation of the arrival process.
