In this paper, we investigate the effect of the prolonged service time at the non-dedicated servers in a pooling system on the system performance. We consider the two-server loss model with exponential interarrival and service times. We show that if the ratio of the mean service time at the dedicated server and the mean prolonged service time at the non-dedicated server exceeds a certain threshold, pooling would become unfavourable. In particular, the threshold is explicitly provided. Moreover, when the degree of the prolonged service time is pre-specified, we show that the pooling system with prolonged service time at non-dedicated servers is not preferred when the work load in the system is greater than a certain threshold.

池化系统中非专用服务器的服务时间延长

在本文中,我们研究了池化系统中非专用服务器的服务时间延长对系统性能的影响。我们考虑具有指数间隔和服务时间的两服务器损失模型。我们表明,如果专用服务器的平均服务时间与非专用服务器的平均延长服务时间之比超过某个阈值,则池化将变得不利。特别是,明确提供了阈值。此外,当服务时间延长的程度是预先指定的时,我们表明当系统中的工作负载大于某个阈值时,在非专用服务器上延长服务时间的池化系统不是首选。
