轮询系统中的队列长度和工作负载

Queue lengths and workloads in polling systems

Onno Boxma, Offer Kella, Kamil Marcin Kosinski

摘要:

我们考虑一个轮询系统:一个具有泊松到达的$N\ge 1$队列的排队系统$Q_1,...,Q_N$由单个服务器以循环顺序(有或没有排队时间)访问。对于这个系统,我们推导出概率生成函数$\mathscr Q(\cdot)$的联合队长分布在一个平稳周期中的任意时刻,在没有假设的服务纪律。我们还推导了在任意时刻的联合工作负荷分布的Laplace- Stieltjes变换$\mathscr W(\cdot)$。我们表示$\mathscr Q$和$\mathscr W$的概率生成函数的联合队列长度分布在访问开始,${\mathscr V}_{b_i}(\cdot)$,和访问完成,${\mathscr V}_{c_i}(\cdot)$,在$Q_i$,$i=1,...,N$。众所周知,${\mathscr V}_{b_i}$和${\mathscr V}_{c_i}$可以在多种情况下计算。此外,我们建立了一个工作量分解结果。

英文摘要:

We consider a polling system: a queueing system of $N\ge 1$ queues with Poisson arrivals $Q_1,...,Q_N$ visited in a cyclic order (with or without switchover times) by a single server. For this system we derive the probability generating function $\mathscr Q(\cdot)$ of the joint queue length distribution at an arbitrary epoch in a stationary cycle, under no assumptions on service disciplines. We also derive the Laplace-Stieltjes transform $\mathscr W(\cdot)$ of the joint workload distribution at an arbitrary epoch. We express $\mathscr Q$ and $\mathscr W$ in the probability generating functions of the joint queue length distribution at visit beginnings, ${\mathscr V}_{b_i}(\cdot)$, and visit completions, ${\mathscr V}_{c_i}(\cdot)$, at $Q_i$, $i=1,...,N$. It is well known that ${\mathscr V}_{b_i}$ and ${\mathscr V}_{c_i}$ can be computed in a broad variety of cases. Furthermore, we establish a workload decomposition result.
