A polling model with smart customers
In this paper we consider a single-server, cyclic polling system with switch-over times. A distinguishing feature of the model is that the rates of the Poisson arrival processes at the various queues depend on the server location. For this model we study the joint queue length distribution at polling epochs and departure epochs. We also study the marginal queue length distribution at arrival ep...
متن کاملA Polling Model with Retrial Customers
A polling model with n stations and switchover times is considered. The customers are of n different types, arrive to the system according to the Poisson distribution in batches of random size, and if they find the server unavailable, they start to make retrials until succeed to find a position for service. Each batch may contain customers of different types while the numbers of customers belon...
متن کاملPolling Systems with Positive and Negative Customers
We study Polling Systems (POLS) with both positive and negative customers, a direction not yet pursued in the literature on POLS. We analyze the Gated, Exhaustive and Globally-Gated service regimes and derive expressions for the Probability Generating Functions (PGFs) of the system’s states and for the Laplace-Stieltjes Transforms of the waiting times. Since the transforms depend on an unknown ...
متن کاملA Polling Model with Reneging at Polling Instants
In this paper we consider a single-server, cyclic polling system with switch-over times and Poisson arrivals. The service disciplines that are discussed, are exhaustive and gated service. The novel contribution of the present paper is that we consider the reneging of customers at polling instants. In more detail, whenever the server starts or ends a visit to a queue, some of the customers waiti...
متن کاملA Polling Model with Multiple Priority Levels
In this paper we consider a single-server cyclic polling system. Between visits to successive queues, the server is delayed by a random switch-over time. The order in which customers are served in each queue is determined by a priority level that is assigned to each customer at his arrival. For this situation the following service disciplines are considered: gated, exhaustive, and globally gate...
