摘要:

在本文中,我们利用在早期的研究中得到的结果,为整个批次的逗留时间$Ω$的$M^{[X]}/M/1$处理器共享(PS)队列中,以推导出这个随机变量的互补概率分布函数的渐近行为,即$P(Ω>x)$的行为时,$x$趋于无穷大。我们精确地表明,到一个乘法因子,大$x$的行为$P(Ω>x)$是相同的数量级的$P(ω>x)$,其中$ω$是一个任意的工作是系统的逗留时间。从实践的角度来看,这意味着如果系统必须被设计为保证工件的处理时间,那么系统也可以通过引入边际量的处理能力来保证整个批次的处理时间。

英文摘要:

In this paper, we exploit results obtained in an earlier study for the Laplace transform of the sojourn time $Ω$ of an entire batch in the $M^{[X]}/M/1$ Processor Sharing (PS) queue in order to derive the asymptotic behavior of the complementary probability distribution function of this random variable, namely the behavior of $P(Ω>x)$ when $x$ tends to infinity. We precisely show that up to a multiplying factor, the behavior of $P(Ω>x)$ for large $x$ is of the same order of magnitude as $P(ω>x)$, where $ω$ is the sojourn time of an arbitrary job is the system. From a practical point of view, this means that if a system has to be dimensioned to guarantee processing time for jobs then the system can also guarantee processing times for entire batches by introducing a marginal amount of processing capacity.
