具有单个共享服务器的排队网络中的等待时间

Waiting times in queueing networks with a single shared server

Marko Boon, Rob van der Mei, Erik Winands

摘要:

我们研究了一个排队网络,它有一个共享服务器,以循环顺序服务于队列。外部顾客到达队列服从独立的泊松过程。完成服务后,客户要么离开系统,要么被路由到另一个队列。该模型是非常通用的,并发现在计算机系统,通信网络,制造系统和机器人技术中的许多应用。所介绍的网络的特殊情况包括著名的轮询模型,串联排队,系统与一个等候室,多阶段模型与并行队列,以及许多其他。该模型的一个复杂因素是,内部重新路由的客户不根据泊松过程到达各个队列,导致标准技术找到等待时间分布失败。本文提出了一种新的方法,得到稳态等待时间分布的Laplace-斯蒂尔切斯变换的精确表达式。该方法可以应用于各种各样的模型,缺乏等待时间分布的分析,直到现在。

英文摘要:

We study a queueing network with a single shared server that serves the queues in a cyclic order. External customers arrive at the queues according to independent Poisson processes. After completing service, a customer either leaves the system or is routed to another queue. This model is very generic and finds many applications in computer systems, communication networks, manufacturing systems, and robotics. Special cases of the introduced network include well-known polling models, tandem queues, systems with a waiting room, multi-stage models with parallel queues, and many others. A complicating factor of this model is that the internally rerouted customers do not arrive at the various queues according to a Poisson process, causing standard techniques to find waiting-time distributions to fail. In this paper we develop a new method to obtain exact expressions for the Laplace-Stieltjes transforms of the steady-state waiting-time distributions. This method can be applied to a wide variety of models which lacked an analysis of the waiting-time distribution until now.
