Joke Blom, Koen de Turck, Michel Mandjes

摘要:

本文研究了马尔可夫调制的M/M/ $\infty$队列,重点研究了系统中作业数的相关结构。主要结果描述了系统的渐近行为下的一个特定的缩放模型参数的功能中心极限定理。更具体地说,依赖于鞅中心极限定理,这一结果是成立的,覆盖的情况下,到达率由一个因素$N$和$N^α$的背景过程的转移率加快,一些$α>0$。结果揭示了一个有趣的二分法,$α>1$和$α<1$分别具有关键不同的行为。的限制高斯过程,这是Ornstein-Uhlenbeck型,明确确定,它是根据明确的结果的平均值,方差和协方差的系统中的工作数量。

英文摘要:

In this paper we study the Markov-modulated M/M/$\infty$ queue, with a focus on the correlation structure of the number of jobs in the system. The main results describe the system's asymptotic behavior under a particular scaling of the model parameters in terms of a functional central limit theorem. More specifically, relying on the martingale central limit theorem, this result is established, covering the situation in which the arrival rates are sped up by a factor $N$ and the transition rates of the background process by $N^α$, for some $α>0$. The results reveal an interesting dichotomy, with crucially different behavior for $α>1$ and $α<1$, respectively. The limiting Gaussian process, which is of the Ornstein-Uhlenbeck type, is explicitly identified, and it is shown to be in accordance with explicit results on the mean, variances and covariances of the number of jobs in the system.
