Abstract
We introduce the concept of inert customers in a generalized queue with signals. A signal interacts with the customers when it arrives in a non empty queue. Then, it disappears instantaneously. Ordinary customers wait for service and eventually receive service if they do not interact with a signal heforehand. An inert customer does not receive service. It stays in the queue until an interaction with a signal makes it disappear. As it is present in the queue, it has an effect on the service capacity. We consider multiple classes of ordinary customers and a symmetric queueing discipline for ordinary and inert customers. In this paper we consider two types of interaction between signals and inert customers: the deletion of one inert customer and the deletion of a group of inert customers. Despite this deep modification of the model, the queue is still quasi-reversible. Therefore we prove that such a network of queues have a steady-state product form solution.
We illustrate this approach with various examples consisting in PS and LIFO queues.
