A two-queue polling model with two priority levels in the first queue
In this paper we consider a single-server cyclic polling system consisting of two queues. Between visits to successive queues, the server is delayed by a random switch-over time. Two types of customers arrive at the first queue: high and low priority customers. For this situation the following service disciplines are considered: gated, globally gated, and exhaustive. We study the cycle time dis...
متن کاملA two-queue polling model with priority on one queue and heavy-tailed On/Off sources: a heavy-traffic limit
We consider a single-server polling system consisting of two queues of fluid with arrival process generated by a big number of heavy-tailed On/Off sources, and application in road traffic and communication systems. Classj fluid is assigned to queue j, j = 1,2. Server 2 visits both queues to process or let pass through it the corresponding fluid class. If there is class-2 fluid in the system, it...
متن کاملOn the optimal control of a two-queue polling model
This paper deals with two M/M/1 queues served by a single server with threshold switching. Our main goal is to solve the Poisson equation and, as a result, give expressions for the long-run expected average cost of holding units and switching actions of the server, and the bias vector.
متن کاملOptimal routing in two-queue polling systems
We consider a polling system with two queues, exhaustive service, no switch-over times and exponential service times with rate μ in each queue. The waiting cost depends on the position of the queue relative to the server: It costs a customer c per time unit to wait in the busy queue (where the server is) and d per time unit in the idle queue (where no server is). Customers arrive according to a...
متن کاملA Finite Capacity Priority Queue with Discouragement
In this paper we report on a study of a two level preemptive priority queue with balking and reneging for lower priority level. The inter-arrival and the service times for both levels follow exponential distribution. We use a finite difference equation approach for solving the balance equations of the governing queuing model whose states are described by functions of one independent variable. H...
