摘要
考虑带关闭和启动期的休假可中止的Geom/Geom/1单重工作休假排队。服务员在休假期间并未完全停止工作而是以较低的速率为顾客服务。运用拟生灭链和矩阵几何解方法给出了该模型的稳态队长和逗留时间的概率母函数,并证明了队长和逗留时间的随机分解结构,可将所得到的结果用于光纤通信系统中网关路由器的性能分析。
The Geom/Geom/1 single-working vacation queue with set-up period and vacation interruption was considered.The server serves customers at a lower rate during the working vacation rather than stops serving customers.Using quasi-birth-death chain and matrix-geometric solution method,the probability generating function for queue size and sojourn time was obtained.Additionally,the structure of stochastic decomposition of the queue size and the sojourn time was proved.The obtained results can be applied in analysis of gateway router in fiber communication networks.
